Paristrion ( Greek : Παρίστριον , lit. 'beside the Ister '), or Paradounabon / Paradounabis ( Παραδούναβον / Παραδούναβις ), which is preferred in official documents, was a Byzantine province covering the southern bank of the Lower Danube ( Moesia Inferior ) in the 11th and 12th centuries.
202-577: Although Byzantine authors use the term to describe the lands along the Danube in general, the province of Paristrion seems to have comprised mostly modern Dobruja . It is not certain exactly when the province was established: the Romanian scholar Nicolae Bănescu considered that it was established immediately after the end of the Rus'–Byzantine War of 970–971 , while others, such as Vasil Zlatarski , thought it
404-642: A pivotal role in elevating the status of Christianity in Rome, decriminalizing Christian practice and ceasing Christian persecution in a period referred to as the Constantinian shift . This initiated the Christianization of the Roman Empire . Constantine is associated with the religiopolitical ideology known as Caesaropapism , which epitomizes the unity of church and state. He founded
606-568: A saint , she is traditionally credited for the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius . He began his career by campaigning in the eastern provinces (against the Persians ) before being recalled in the west (in AD ;305) to fight alongside his father in the province of Britannia . After his father's death in 306, Constantine
808-462: A sensational victory against Bulgaria and the Kievan Rus' in 971. John in particular was an astute administrator who reformed military structures and implemented effective fiscal policies. After John's death, Constantine VII's grandsons Basil II and Constantine VIII ruled jointly for half a century, although the latter exercised no real power before Basil's death in 1025. Their early reign
1010-511: A Christian, he waited to be baptised on his deathbed, believing that the baptism would release him of any sins he committed in the course of carrying out his policies while emperor. He supported the Church financially, built basilicas, granted privileges to clergy (such as exemption from certain taxes), promoted Christians to high office, and returned property confiscated during the long period of persecution. His most famous building projects include
1212-506: A collection of panegyrics from the late 3rd and early 4th centuries, provides valuable information on the politics and ideology of the tetrarchic period and the early life of Constantine. Contemporary architecture—such as the Arch of Constantine in Rome and palaces in Gamzigrad and Córdoba — epigraphic remains, and the coinage of the era complement the literary sources. Constantine
1414-415: A combination of external threats and internal instabilities caused the Roman state to splinter as regional armies acclaimed their generals as "soldier-emperors". One of these, Diocletian ( r. 284–305 ), seeing that the state was too big to be ruled by one man, attempted to fix the problem by instituting a Tetrarchy , or rule of four, and dividing the empire into eastern and western halves. Although
1616-645: A considerable increase in the size of urban settlements, together with a notable upsurge in new towns. Trade was also flourishing; the Venetians, the Genoese and others opened up the ports of the Aegean to commerce, shipping goods from the Crusader states and Fatimid Egypt to the west and trading with the empire via Constantinople. Manuel's death on 24 September 1180 left his 11-year-old son Alexios II Komnenos on
1818-464: A contested legacy to Roman identity and to associate negative connotations from ancient Latin literature. The adjective "Byzantine", which derived from Byzantion (Latinised as Byzantium ), the name of the Greek settlement Constantinople was established on, was only used to describe the inhabitants of that city; it did not refer to the empire, which they called Romanía —"Romanland". After
2020-542: A distinction between the earlier Roman Empire and the later Byzantine Empire . During the earlier Pax Romana period, the western parts of the empire became increasingly Latinised , while the eastern parts largely retained their preexisting Hellenistic culture . This created a dichotomy between the Greek East and Latin West . These cultural spheres continued to diverge after Constantine I ( r. 324–337 ) moved
2222-536: A grand adventus in the city which was met with jubilation. Maxentius' body was fished out of the Tiber and decapitated, and his head was paraded through the streets for all to see. After the ceremonies, the disembodied head was sent to Carthage, and Carthage offered no further resistance. Unlike his predecessors, Constantine neglected to make the trip to the Capitoline Hill and perform customary sacrifices at

The figure was otherwise rare and is uncommon in imperial iconography and propaganda before the 320s. It was not completely unknown, however, being an abbreviation of the Greek word chrēston (good), having previously appeared on the coins of Ptolemy III Euergetes in the 3rd century BC. Following Constantine, centuries of Christians invoked
2626-565: A large donative pledge to any who would support him as emperor, most of Constantine's army remained loyal to their emperor, and Maximian was soon compelled to leave. When Constantine heard of the rebellion, he abandoned his campaign against the Franks and marched his army up the Rhine. At Cabillunum ( Chalon-sur-Saône ), he moved his troops onto waiting boats to row down the slow waters of the Saône to

When order had been restored, the crusaders and the Venetians proceeded to implement their agreement; Baldwin of Flanders was elected emperor of a new Latin Empire , and the Venetian Thomas Morosini was chosen as patriarch. The lands divided up among the leaders included most of

It was governed by a katepano or a doux , and was probably based at Dorostolon (modern Silistra ), where a Byzantine strategia ("generalcy") is indeed attested in the 970s. In the aftermath of his victory over the Rus', Emperor John I Tzimiskes (r. 969–976) appointed general Leo Sarakenopoulos as commander over north-eastern Bulgaria , based at Pereyaslavets /Ioannopolis. Sarakenopoulos and his subordinates engaged in major fortification activities in
3232-512: A lengthy conflict against Sasanid Persia and ended in 363 with the death of his son-in-law Julian . The short Valentinianic dynasty , occupied with wars against barbarians , religious debates, and anti-corruption campaigns, ended in the East with the death of Valens at the Battle of Adrianople in 378. Valens's successor, Theodosius I ( r. 379–395 ), restored political stability in

This encompassed most of the Balkans , all of modern Greece, Turkey, Syria , Palestine ; North Africa, primarily with modern Egypt and Libya ; the Aegean islands along with Crete , Cyprus and Sicily , and a small settlement in Crimea . The landscape of the Empire was defined by the fertile fields of Anatolia , long mountain ranges and rivers such as
3636-487: A long evening of drinking, Galerius granted the request. Constantine's later propaganda describes how he fled the court in the night, before Galerius could change his mind. He rode from post-house to post-house at high speed, hamstringing every horse in his wake. By the time Galerius awoke the following morning, Constantine had fled too far to be caught. Constantine joined his father in Gaul , at Bononia ( Boulogne ) before
3838-460: A military support, which Maxentius accepted. According to Eusebius, inter-regional travel became impossible, and there was military buildup everywhere. There was "not a place where people were not expecting the onset of hostilities every day". Constantine's advisers and generals cautioned against preemptive attack on Maxentius; even his soothsayers recommended against it, stating that the sacrifices had produced unfavourable omens. Constantine, with
4040-490: A palace complex in the northeastern part of the city. To the south of his palace, he ordered the construction of a large formal audience hall and a massive imperial bathhouse. He sponsored many building projects throughout Gaul during his tenure as emperor of the West, especially in Augustodunum ( Autun ) and Arelate ( Arles ). According to Lactantius, Constantine followed a tolerant policy towards Christianity, although he
4242-453: A result of a debilitating sickness taken in the winter of 304–305, announced his resignation. In a parallel ceremony in Milan , Maximian did the same. Lactantius states that Galerius manipulated the weakened Diocletian into resigning and forced him to accept Galerius' allies in the imperial succession. According to Lactantius, the crowd listening to Diocletian's resignation speech believed, until

Maximinus mobilised against Licinius and seized Asia Minor . A hasty peace was signed on a boat in the middle of the Bosphorus . While Constantine toured Britain and Gaul, Maxentius prepared for war. He fortified northern Italy and strengthened his support in

He was finally overthrown when Isaac II Angelos , surviving an imperial assassination attempt, seized power with the aid of the people and had Andronikos killed. The reign of Isaac II, and more so that of his brother Alexios III , saw the collapse of what remained of the centralised machinery of Byzantine government and defence. Although
4848-417: A speedy and marked improvement. Gradually, however, Andronikos's reign deteriorated. The aristocrats were infuriated against him, and to make matters worse, Andronikos seemed to have become increasingly unbalanced; executions and violence became increasingly common, and his reign turned into a reign of terror. Andronikos seemed almost to seek the extermination of the aristocracy as a whole. The struggle against
5050-550: A spirit that left a deep impression on his followers, inspiring some to believe that he had some form of supernatural guidance, ignored all these cautions. Early in the spring of 312, Constantine crossed the Cottian Alps with a quarter of his army, a force numbering about 40,000. The first town his army encountered was Segusium ( Susa , Italy), a heavily fortified town that shut its gates to him. Constantine ordered his men to set fire to its gates and scale its walls. He took
5252-460: A temple to Aphrodite . Generations later there was the story that a divine vision led Constantine to this spot, and an angel no one else could see led him on a circuit of the new walls. The capital would often be compared to the 'old' Rome as Nova Roma Constantinopolitana , the "New Rome of Constantinople". Constantine was the first emperor to stop the persecution of Christians and to legalize Christianity, along with all other religions/cults in
5454-435: A tolerant and politically skilled man, Constantius advanced through the ranks, earning the governorship of Dalmatia from Emperor Diocletian, another of Aurelian's companions from Illyricum , in 284 or 285. Constantine's mother was Helena , a Greek woman of low social standing from Helenopolis of Bithynia . It is uncertain whether she was legally married to Constantius or merely his concubine . His main language

The final Byzantine emperor, Constantine XI Palaiologos , was last seen casting off his imperial regalia and throwing himself into hand-to-hand combat after the walls of the city were taken. The Empire was centred in what is now Greece and Turkey with Constantinople as its capital. In the 5th century, it controlled the eastern basis of the Mediterranean running east from Singidunum (modern Belgrade ) in
5858-415: A year, rejected it. Constantine sent Galerius an official notice of Constantius' death and his own acclamation. Along with the notice, he included a portrait of himself in the robes of an augustus. The portrait was wreathed in bay . He requested recognition as heir to his father's throne and passed off responsibility for his unlawful ascension on his army, claiming they had "forced it upon him". Galerius
6060-541: Is evidence that some Komnenian heirs had set up a semi-independent state in Trebizond before 1204. According to the historian Alexander Vasiliev , "the dynasty of the Angeloi, Greek in its origin, ... accelerated the ruin of the Empire, already weakened without and disunited within." In 1198, Pope Innocent III broached the subject of a new crusade through legates and encyclical letters. The stated intent of
6262-547: Is impossible to precisely date the foundation of the Byzantine Empire. In a series of conflicts between the third and first centuries BC, the Roman Republic gradually established hegemony over the eastern Mediterranean , while its government ultimately transformed into the one-person rule of an emperor . The Roman Empire enjoyed a period of relative stability until the third century AD , when

Eventually, however, Constantine decided to work on the Greek city of Byzantium , which offered the advantage of having already been extensively rebuilt on Roman patterns of urbanism during the preceding century by Septimius Severus and Caracalla , who had already acknowledged its strategic importance. The city was thus founded in 324, dedicated on 11 May 330 and renamed Constantinopolis ("Constantine's City" or Constantinople in English). Special commemorative coins were issued in 330 to honor
6666-449: Is no consensus on a "foundation date" for the Byzantine Empire, if there was one at all. The growth of the study of "late antiquity" has led to some historians setting a start date in the seventh or eighth centuries. Others believe a "new empire" began during changes in c. 300 AD. Still others hold that these starting points are too early or too late, and instead begin c. 500 . Geoffrey Greatrex believes that it

He also adopted the name "Valerius", the nomen of emperor Diocletian , following his father's ascension as caesar . Constantine probably spent little time with his father who was an officer in the Roman army, part of Emperor Aurelian 's imperial bodyguard. Being described as
7070-466: Is somewhat doubtful, the fact is that he seems to have been far less open in his support of Christianity than Constantine. Therefore, Licinius was prone to see the Church as a force more loyal to Constantine than to the Imperial system in general, as the explanation offered by the Church historian Sozomen . This dubious arrangement eventually became a challenge to Constantine in the West, climaxing in
7272-518: Is the anonymous Origo Constantini , a work of uncertain date which focuses on military and political events to the neglect of cultural and religious matters. Lactantius ' De mortibus persecutorum , a political Christian pamphlet on the reigns of Diocletian and the Tetrarchy , provides valuable but tendentious detail on Constantine's predecessors and early life. The ecclesiastical histories of Socrates , Sozomen , and Theodoret describe

The age of Constantine marked a distinct epoch in the history of the Roman Empire and a pivotal moment in the transition from classical antiquity to the Middle Ages .

During most of its existence, the empire remained

The inhabitants of the empire, now generally termed Byzantines, thought of themselves as Romans ( Romaioi ). Their Islamic neighbours similarly called their empire the "land of the Romans" ( Bilād al-Rūm ), but the people of medieval Western Europe preferred to call them "Greeks" ( Graeci ), due to having

Although she was a capable administrator who temporarily resolved the iconoclasm controversy, the empire was destabilized by her feud with her son. The Bulgars and Abbasids meanwhile inflicted numerous defeats on the Byzantine armies, and the papacy crowned Charlemagne as Roman emperor in 800. In 802,

However, he did visit the Senatorial Curia Julia , and he promised to restore its ancestral privileges and give it a secure role in his reformed government; there would be no revenge against Maxentius' supporters. In response, the Senate decreed him "title of the first name", which meant that his name would be listed first in all official documents, and they acclaimed him as "the greatest augustus". He issued decrees returning property that

The empire was able to expand once more under the Macedonian dynasty , experiencing a two-century-long renaissance .

The Roman army was reorganised to consist of mobile units ( comitatenses ), often around the Emperor, to serve on campaigns against external enemies or Roman rebels, and frontier-garrison troops ( limitanei ) which were capable of countering barbarian raids, but less and less capable, over time, of countering full-scale barbarian invasions . Constantine pursued successful campaigns against

Justinian took advantage of political instability in Italy to attempt the reconquest of lost western territories. The Vandal Kingdom in North Africa was subjugated in 534 by the general Belisarius , who then invaded Italy ; the Ostrogothic Kingdom was destroyed in 554.

The epitomes of Aurelius Victor ( De Caesaribus ), Eutropius ( Breviarium ), Festus ( Breviarium ), and the anonymous author of the Epitome de Caesaribus offer compressed secular political and military histories of the period. Although not Christian, the epitomes paint a favourable image of Constantine but omit reference to Constantine's religious policies. The Panegyrici Latini ,

By 1025, the date of Basil II's death, the Byzantine Empire stretched from Armenia in

His early support dissolved in the wake of heightened tax rates and depressed trade; riots broke out in Rome and Carthage ; and Domitius Alexander was able to briefly usurp his authority in Africa. By 312, he was a man barely tolerated, not one actively supported, even among Christian Italians. In

Constantine recognised the implicit danger in remaining at Galerius' court, where he was held as a virtual hostage. His career depended on being rescued by his father in the West. Constantius was quick to intervene. In the late spring or early summer of 305, Constantius requested leave for his son to help him campaign in Britain. After

The division was merely pragmatic: the empire was called "indivisible" in official panegyric, and both emperors could move freely throughout the empire. In 288, Maximian appointed Constantius to serve as his praetorian prefect in Gaul . Constantius left Helena to marry Maximian's stepdaughter Theodora in 288 or 289. Diocletian divided the empire again in 293, appointing two caesars to rule over further subdivisions of East and West. Each would be subordinate to his respective augustus but would act with supreme authority in his assigned lands. This system would later be called
14140-415: The Empire by land, with the Via Egnatia running from Constantinople to the Albanian coast through Macedonia and the Via Traiana to Adrianople (modern Edirne ), Serdica (modern Sofia ) and Singidunum. By water, Crete, Cyprus and Sicily were key naval points and the main ports connecting Constantinople were Alexandria, Gaza, Caesarea and Antioch. The Aegean sea was considered an internal lake within

The emperor was the centre of the whole administration of the Empire, who the legal historian Kaius Tuori has said was "above the law, within the law, and the law itself"; with a power that is difficult to define and which does not align with our modern understanding of the separation of powers.

He then left for Augusta Treverorum ( Trier ) in Gaul, the Tetrarchic capital of the northwestern Roman Empire. The Franks learned of Constantine's acclamation and invaded Gaul across the lower Rhine over
15554-690: The Praetorian Guard and Imperial Horse Guard . The tombstones of the Imperial Horse Guard were ground up and used in a basilica on the Via Labicana , and their former base was redeveloped into the Lateran Basilica on 9 November 312—barely two weeks after Constantine captured the city. The Legio II Parthica was removed from Albano Laziale , and the remainder of Maxentius' armies were sent to do frontier duty on
15756-470: The Rhine. In the following years, Constantine gradually consolidated his military superiority over his rivals in the crumbling Tetrarchy. In 313, he met Licinius in Milan to secure their alliance by the marriage of Licinius and Constantine's half-sister Constantia. During this meeting, the emperors agreed on the so-called Edict of Milan , officially granting full tolerance to Christianity and all religions in
15958-533: The Roman Empire. In February 313, he met with Licinius in Milan and developed the Edict of Milan, which stated that Christians should be allowed to follow their faith without oppression. This removed penalties for professing Christianity, under which many had been martyred previously , and it returned confiscated Church property. The edict protected all religions from persecution, not only Christianity, allowing anyone to worship any deity that they chose. A similar edict had been issued in 311 by Galerius, senior emperor of
16160-680: The Sassanids occupied the Levant and Egypt and pushed into Asia Minor, while Byzantine control of Italy slipped and the Avars and Slavs ran riot in the Balkans. Although Heraclius repelled a siege of Constantinople in 626 and defeated the Sassanids in 627, this was a pyrrhic victory . The early Muslim conquests soon saw the conquest of the Levant , Egypt , and the Sassanid Empire by
16362-413: The Tetrarchy system quickly failed, the division of the empire proved an enduring concept. Constantine I ( r. 306–337 ) secured sole power in 324. Over the following six years, he rebuilt the city of Byzantium as a capital city , which was renamed Constantinople . Rome , the previous capital, was further from the important eastern provinces and in a less strategically important location; it
16564-560: The Tetrarchy, which granted Christians the right to practise their religion but did not restore any property to them. The Edict of Milan included several clauses which stated that all confiscated churches would be returned, as well as other provisions for previously persecuted Christians. Some scholars think that Helena adopted Christianity as an adult, and according to Eusebius she was converted by Constantine, but other historians debate whether Constantine adopted his mother Helena's Christianity in his youth or whether he adopted it gradually over
16766-417: The Tetrarchy. Diocletian's first appointee for the office of Caesar was Constantius ; his second was Galerius , a native of Felix Romuliana . According to Lactantius , Galerius was a brutal, animalistic man. Although he shared the paganism of Rome's aristocracy, he seemed to them an alien figure, a semi-barbarian. On 1 March, Constantius was promoted to the office of Caesar, and dispatched to Gaul to fight
16968-481: The Turkish invaders at the Battle of Hyelion and Leimocheir , brought troops from the capital and was able to gather an army along the way, a sign that the Byzantine army remained strong and that the defensive program of western Asia Minor was still successful. John and Manuel pursued active military policies, and both deployed considerable resources on sieges and city defences; aggressive fortification policies were at
17170-544: The Veronese forces and Maxentius' praetorian prefect, was in a strong defensive position since the town was surrounded on three sides by the Adige . Constantine sent a small force north of the town in an attempt to cross the river unnoticed. Ruricius sent a large detachment to counter Constantine's expeditionary force but was defeated. Constantine's forces successfully surrounded the town and laid siege. Ruricius gave Constantine
17372-610: The West, Khosrow I of the Sasanian Empire invaded Byzantine territory and sacked Antioch in 540. Meanwhile, the emperor's internal reforms and policies began to falter, not helped by a devastating plague that killed a large proportion of the population and severely weakened the empire's social and financial stability. The most difficult period of the Ostrogothic war, against their king Totila , came during this decade, while divisions among Justinian's advisors undercut
17574-401: The West. Zeno ( r. 474–491 ) convinced the problematic Ostrogoth king Theodoric to take control of Italy from Odoacer, which he did; dying with the empire at peace, Zeno was succeeded by Anastasius I ( r. 491–518 ). Although his Monophysitism brought occasional issues, Anastasius was a capable administrator and instituted several successful financial reforms including
17776-596: The Western provinces to achieve an economic revival that continued until the close of the century. It has been argued that Byzantium under the Komnenian rule was more prosperous than at any time since the Persian invasions of the 7th century. During the 12th century, population levels rose and extensive tracts of new agricultural land were brought into production. Archaeological evidence from both Europe and Asia Minor shows
17978-522: The abolition of the chrysargyron tax . He was the first emperor to die with no serious problems affecting his empire since Diocletian. The reign of Justinian I was a watershed in Byzantine history. Following his accession in 527, the law-code was rewritten as the influential Corpus Juris Civilis and Justinian produced extensive legislation on provincial administration; he reasserted imperial control over religion and morality through purges of non-Christians and "deviants"; and having ruthlessly subdued
18180-590: The administration's response. He also did not fully heal the divisions in Chalcedonian Christianity , as the Second Council of Constantinople failed to make a real difference. Justinian died in 565; his reign saw more success than that of any other Byzantine emperor, yet he left his empire under massive strain. Financially and territorially overextended, Justin II ( r. 565–578 )
18382-568: The aristocracy turned into wholesale slaughter, while the emperor resorted to ever more ruthless measures to shore up his regime. Despite his military background, Andronikos failed to deal with Isaac Komnenos of Cyprus, Béla III of Hungary who reincorporated Croatian territories into Hungary, and Stephen Nemanja of Serbia who declared his independence from the Byzantine Empire. Yet, none of these troubles compared to William II of Sicily 's invasion force of 300 ships and 80,000 men, arriving in 1185 and sacking Thessalonica . Andronikos mobilised
18584-558: The beginning of the Renaissance , there were more critical appraisals of his reign with the rediscovery of anti-Constantinian sources. Trends in modern and recent scholarship have attempted to balance the extremes of previous scholarship. Constantine was a ruler of major importance and has always been a controversial figure. The fluctuations in his reputation reflect the nature of the ancient sources for his reign. These are abundant and detailed, but they have been strongly influenced by
18786-403: The capital to Constantinople and legalised Christianity . Under Theodosius I ( r. 379–395 ), Christianity became the state religion , and other religious practices were proscribed . Greek gradually replaced Latin for official use as Latin fell into disuse. The empire experienced several cycles of decline and recovery throughout its history, reaching its greatest extent after the fall of
18988-495: The capital, and Alexios Angelos was elevated to the throne as Alexios IV along with his blind father Isaac. Alexios IV and Isaac II were unable to keep their promises and were deposed by Alexios V . The crusaders again took the city on 13 April 1204 , and Constantinople was subjected to pillage and massacre by the rank and file for three days. Many priceless icons, relics and other objects later turned up in Western Europe ,
19190-429: The cipher of Christ. Having this sign (☧), his troops stood to arms." Eusebius describes a vision that Constantine had while marching at midday in which "he saw with his own eyes the trophy of a cross of light in the heavens, above the sun, and bearing the inscription, In Hoc Signo Vinces " ("In this sign thou shalt conquer"). In Eusebius's account, Constantine had a dream the following night in which Christ appeared with
19392-469: The city had collapsed so severely that it was now little more than a cluster of villages separated by fields. On 2 April 1453, Sultan Mehmed 's army of 80,000 men and large numbers of irregulars laid siege to the city. Despite a desperate last-ditch defence of the city by the massively outnumbered Christian forces (c. 7,000 men, 2,000 of whom were foreign), Constantinople finally fell to the Ottomans after
19594-634: The city of Constantinople and made it the capital of the Empire, which remained so for over a millennium. Born in Naissus , in Dardania within Moesia Superior (now Niš , Serbia), Constantine was the son of Flavius Constantius , a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy . His mother, Helena , was a Greek woman of low birth, probably from Asia Minor in modern Turkey . Later canonised as
19796-413: The coinage of Constantine advertised Mars as his patron. From 310 on, Mars was replaced by Sol Invictus , a god conventionally identified with Apollo. There is little reason to believe that either the dynastic connection or the divine vision are anything other than fiction, but their proclamation strengthened Constantine's claims to legitimacy and increased his popularity among the citizens of Gaul. By
19998-527: The continuous raids of the Pechenegs . The population was withdrawn to a few large fortified centres, and the Pechenegs were allowed to settle in the province as allies and colonists (termed mixobarbaroi by contemporary authors) and kept pacified through subsidies and through a vibrant trade . It was not until the early 1070s that the Pechenegs launched an open rebellion , and posed a constant threat to
20200-490: The course of his life. Constantine possibly retained the title of pontifex maximus which emperors bore as heads of the ancient Roman religion until Gratian renounced the title. According to Christian writers, Constantine was over 40 when he finally declared himself a Christian, making it clear that he owed his successes to the protection of the Christian High God alone. Despite these declarations of being
20402-550: The crusade was to conquer Egypt , the centre of Muslim power in the Levant. The Crusader army arrived at Venice in the summer of 1202 and hired the Venetian fleet to transport them to Egypt. As a payment to the Venetians, they captured the (Christian) port of Zara in Dalmatia , which was a vassal city of Venice, it had rebelled and placed itself under Hungary's protection in 1186. Shortly afterward, Alexios IV Angelos , son of
20604-430: The demotion and continued to style himself as augustus on his coinage, even as other members of the Tetrarchy referred to him as a caesar on theirs. Maximinus was frustrated that he had been passed over for promotion while the newcomer Licinius had been raised to the office of augustus and demanded that Galerius promote him. Galerius offered to call both Maximinus and Constantine "sons of the augusti", but neither accepted
20806-504: The deposed and blinded Emperor Isaac II, made contact with the Crusaders. Alexios offered to reunite the Byzantine church with Rome, pay the Crusaders 200,000 silver marks, join the crusade, and provide all the supplies they needed to reach Egypt. The crusaders arrived at Constantinople in the summer of 1203 and quickly attacked , starting a major fire that damaged large parts of the city, and briefly seized control. Alexios III fled from
21008-487: The earlier rupture in their relations, Maxentius was eager to present himself as his father's devoted son after his death. He began minting coins with his father's deified image, proclaiming his desire to avenge Maximian's death. Constantine initially presented the suicide as an unfortunate family tragedy. By 311, however, he was spreading another version. According to this, after Constantine had pardoned him, Maximian planned to murder Constantine in his sleep. Fausta learned of
21210-475: The east by allowing the Goths to settle in Roman territory; he also twice intervened in the western half, defeating the usurpers Magnus Maximus and Eugenius in 388 and 394 respectively. He actively condemned paganism , confirmed the primacy of Nicene Christianity over Arianism , and established Christianity as the Roman state religion . He was the last emperor to rule both the western and eastern halves of
21412-433: The east to Calabria in southern Italy in the west. Many successes had been achieved, ranging from the conquest of Bulgaria to the annexation of parts of Georgia and Armenia, and the reconquests of Crete , Cyprus , and the important city of Antioch . These were not temporary tactical gains but long-term reconquests. At the same time, Byzantium was faced with new enemies. Its provinces in southern Italy were threatened by
21614-408: The eastern front by the spring of 303, in time to witness the beginnings of Diocletian's " Great Persecution ", the most severe persecution of Christians in Roman history. In late 302, Diocletian and Galerius sent a messenger to the oracle of Apollo at Didyma with an inquiry about Christians. Constantine could recall his presence at the palace when the messenger returned and Diocletian accepted
21816-475: The ecclesiastic disputes of Constantine's later reign. Written during the reign of Theodosius II (r. 402–450), a century after Constantine's reign, these ecclesiastical historians obscure the events and theologies of the Constantinian period through misdirection, misrepresentation, and deliberate obscurity. The contemporary writings of the orthodox Christian Athanasius and the ecclesiastical history of
22018-400: The economy and the arts. His refusal to participate in the war increased his popularity among his people and strengthened his power base in the West. Maximian returned to Rome in the winter of 307–308 but soon fell out with his son. In early 308, after a failed attempt to usurp Maxentius' title, Maximian returned to Constantine's court. On 11 November 308, Galerius called a general council at
22220-471: The elder Emperor Maximian and needed a new source of legitimacy. In a speech delivered in Gaul on 25 July 310, the anonymous orator reveals a previously unknown dynastic connection to Claudius II , a 3rd-century emperor famed for defeating the Goths and restoring order to the empire. Breaking away from tetrarchic models, the speech emphasizes Constantine's ancestral prerogative to rule, rather than principles of imperial equality. The new ideology expressed in
22422-537: The emperor's role as the leader of the Christian world, John marched into the Holy Land at the head of the combined forces of the empire and the Crusader states; yet despite his efforts in leading the campaign, his hopes were disappointed by the treachery of his Crusader allies. In 1142, John returned to press his claims to Antioch, but he died in the spring of 1143 following a hunting accident. John's chosen heir
22624-457: The emperor's traditional purple robes . Constantine accepted the decision, knowing that it would remove doubts as to his legitimacy. Constantine's share of the empire consisted of Britain, Gaul, and Spain, and he commanded one of the largest Roman armies which was stationed along the important Rhine frontier. He remained in Britain after his promotion to emperor, driving back the tribes of
22826-533: The empire's eastern defences. The emergency lent weight to the military aristocracy in Anatolia, who in 1068 secured the election of one of their own, Romanos Diogenes , as emperor. In the summer of 1071, Romanos undertook a massive eastern campaign to draw the Seljuks into a general engagement with the Byzantine army. At the Battle of Manzikert , Romanos suffered a surprise defeat against Sultan Alp Arslan and
23028-496: The empire's fall, early modern scholars referred to the empire by many names, including the "Empire of Constantinople", the "Empire of the Greeks", the "Eastern Empire", the "Late Empire", the "Low Empire", and the "Roman Empire". The increasing use of "Byzantine" and "Byzantine Empire" likely started with the 15th-century historian Laonikos Chalkokondyles , whose works were widely propagated, including by Hieronymus Wolf . "Byzantine"
23230-499: The empire, gaining only short-term success. To avoid another sacking of the capital by the Latins, he forced the Church to submit to Rome, again a temporary solution for which the peasantry hated Michael and Constantinople. The efforts of Andronikos II and later his grandson Andronikos III marked Byzantium's last genuine attempts to restoring the glory of the empire. However, the use of mercenaries by Andronikos II often backfired, with
23432-442: The empire. The document had special benefits for Christians, legalizing their religion and granting them restoration for all property seized during Diocletian's persecution. It repudiates past methods of religious coercion and used only general terms to refer to the divine sphere—"Divinity" and "Supreme Divinity", summa divinitas . The conference was cut short, however, when news reached Licinius that his rival Maximinus had crossed
23634-468: The empire; after his death, the West would be destabilised by a succession of "soldier-emperors", unlike the East, where administrators would continue to hold power. Theodosius II ( r. 408–450 ) largely left the rule of the east to officials such as Anthemius , who constructed the Theodosian Walls to defend Constantinople, now firmly entrenched as Rome's capital. Theodosius' reign
23836-522: The end of the Norman threat during Alexios' reign. Alexios's son John II Komnenos succeeded him in 1118 and ruled until 1143. John was a pious and dedicated emperor who was determined to undo the damage to the empire suffered at the Battle of Manzikert half a century earlier. Famed for his piety and his remarkably mild and just reign, John was an exceptional example of a moral ruler at a time when cruelty
24038-679: The enemies that surrounded it. To maintain his campaigns against the Latins, Michael pulled troops from Asia Minor and levied crippling taxes on the peasantry, causing much resentment. Massive construction projects were completed in Constantinople to repair the damage of the Fourth Crusade, but none of these initiatives were of any comfort to the farmers in Asia Minor suffering raids from Muslim ghazis. Rather than holding on to his possessions in Asia Minor, Michael chose to expand
24240-640: The event. The new city was protected by the relics of the True Cross , the Rod of Moses and other holy relics, though a cameo now at the Hermitage Museum also represented Constantine crowned by the tyche of the new city. The figures of old gods were either replaced or assimilated into a framework of Christian symbolism . Constantine built the new Church of the Holy Apostles on the site of
24442-402: The field bearing unfamiliar symbols on their standards and their shields. According to Lactantius "Constantine was directed in a dream to cause the heavenly sign to be delineated on the shields of his soldiers, and so to proceed to battle. He did as he had been commanded, and he marked on their shields the letter Χ, with a perpendicular line drawn through it and turned round thus at the top, being
24644-420: The first charge. His horse guards and praetorians initially held their position, but they broke under the force of a Constantinian cavalry charge; they also broke ranks and fled to the river. Maxentius rode with them and attempted to cross the bridge of boats ( Ponte Milvio ), but he was pushed into the Tiber and drowned by the mass of his fleeing soldiers. Constantine entered Rome on 29 October 312 and staged
24846-523: The former Byzantine possessions. Although Venice was more interested in commerce than conquering territory, it took key areas of Constantinople, and the Doge took the title of " Lord of a Quarter and Half a Quarter of the Roman Empire ". After the sack of Constantinople in 1204 by Latin crusaders, two Byzantine successor states were established: the Empire of Nicaea and the Despotate of Epirus . A third,
25048-554: The fort, allowing the Ottomans (who were hired as mercenaries during the civil war by John VI Kantakouzenos ) to establish themselves in Europe. By the time the Byzantine civil wars had ended, the Ottomans had defeated the Serbians and subjugated them as vassals. Following the Battle of Kosovo , much of the Balkans became dominated by the Ottomans. Constantinople by this stage was underpopulated and dilapidated. The population of
25250-414: The great civil war of 324. Constantine's Christian eulogists present the war as a battle between Christianity and paganism; Licinius, aided by Gothic mercenaries, represented the past and ancient paganism, while Constantine and his Franks marched under the standard of the labarum . Outnumbered but fired by their zeal, Constantine's army emerged victorious in the Battle of Adrianople . Licinius fled across
25452-431: The heart of their imperial military policies. Despite the defeat at Myriokephalon, the policies of Alexios, John and Manuel resulted in vast territorial gains, increased frontier stability in Asia Minor, and secured the stabilisation of the empire's European frontiers. From c. 1081 to c. 1180 , the Komnenian army assured the empire's security, enabling Byzantine civilisation to flourish. This allowed
25654-598: The honours that he had granted to leaders of the Senate were also invalidated. Constantine also attempted to remove Maxentius' influence on Rome's urban landscape. All structures built by him were rededicated to Constantine, including the Temple of Romulus and the Basilica of Maxentius . At the focal point of the basilica, a stone statue was erected of Constantine holding the Christian labarum in its hand. Its inscription bore
25856-404: The imperial court's demands for universal persecution. On 23 February 303, Diocletian ordered the destruction of Nicomedia' s new church, condemned its scriptures to the flames, and had its treasures seized. In the months that followed, churches and scriptures were destroyed, Christians were deprived of official ranks, and priests were imprisoned. It is unlikely that Constantine played any role in
26058-403: The last moment, that Diocletian would choose Constantine and Maxentius (Maximian's son) as his successors. It was not to be: Constantius and Galerius were promoted to augusti , while Severus and Maximinus , Galerius' nephew, were appointed their caesars respectively. Constantine and Maxentius were ignored. Some of the ancient sources detail plots that Galerius made on Constantine's life in
26260-726: The later part of his reign, John focused his activities on the East, personally leading numerous campaigns against the Turks in Asia Minor. His campaigns fundamentally altered the balance of power in the East, forcing the Turks onto the defensive, while retaking many towns, fortresses, and cities across the peninsula for the Byzantines. He defeated the Danishmend Emirate of Melitene and reconquered all of Cilicia , while forcing Raymond of Poitiers , Prince of Antioch, to recognise Byzantine suzerainty. In an effort to demonstrate
26462-418: The measures he took to reform the government of the empire have been praised by historians. According to the historian George Ostrogorsky , Andronikos was determined to root out corruption: under his rule, the sale of offices ceased; selection was based on merit, rather than favouritism; and officials were paid an adequate salary to reduce the temptation of bribery. In the provinces, Andronikos's reforms produced
26664-530: The message which the statue illustrated: "By this sign, Constantine had freed Rome from the yoke of the tyrant." Constantine also sought to upstage Maxentius' achievements. For example, the Circus Maximus was redeveloped so that its seating capacity was 25 times larger than that of Maxentius' racing complex on the Via Appia . Maxentius' strongest military supporters were neutralised when he disbanded
26866-592: The mid-13th century it had lost much of southern Anatolia. The weakening of the Sultanate of Rûm following the Mongol invasion in 1242–1243 allowed many beyliks and ghazis to set up their own principalities in Anatolia, weakening the Byzantine hold on Asia Minor. Two centuries later, one of the Beys of these beyliks, Osman I , would establish the Ottoman Empire that would eventually conquer Constantinople. However,
27068-524: The middle of 310, Galerius had become too ill to involve himself in imperial politics. His final act survives: a letter to provincials posted in Nicomedia on 30 April 311, proclaiming an end to the persecutions, and the resumption of religious toleration. Eusebius maintains "divine providence [...] took action against the perpetrator of these crimes" and gives a graphic account of Galerius' demise: "Without warning suppurative inflammation broke out round
27270-408: The middle of his genitals, then a deep-seated fistula ulcer; these ate their way incurably into his innermost bowels. From them came a teeming indescribable mass of worms, and a sickening smell was given off, for the whole of his hulking body, thanks to over eating, had been transformed even before his illness into a huge lump of flabby fat, which then decomposed and presented those who came near it with
27472-455: The military city of Carnuntum ( Petronell-Carnuntum , Austria) to resolve the instability in the western provinces. In attendance were Diocletian, briefly returned from retirement, Galerius, and Maximian. Maximian was forced to abdicate again and Constantine was again demoted to caesar. Licinius , one of Galerius' old military companions, was appointed augustus in the western regions. The new system did not last long: Constantine refused to accept
27674-419: The miraculous or the supernatural when justifying or describing their warfare. Constantine deployed his own forces along the whole length of Maxentius' line. He ordered his cavalry to charge, and they broke Maxentius' cavalry. He then sent his infantry against Maxentius' infantry, pushing many into the Tiber where they were slaughtered and drowned. The battle was brief, and Maxentius' troops were broken before
27876-420: The months following Diocletian's abdication. They assert that Galerius assigned Constantine to lead an advance unit in a cavalry charge through a swamp on the middle Danube, made him enter into single combat with a lion, and attempted to kill him in hunts and wars. Constantine always emerged victorious: the lion emerged from the contest in a poorer condition than Constantine; Constantine returned to Nicomedia from
28078-546: The most capable Byzantine emperors, withstood continued Arab attacks, civil unrest, and natural disasters, and reestablished the state as a major regional power. Leo's reign produced the Ecloga , a new code of law to succeed that of Justinian II, and continued to reform the "theme system" in order to lead offensive campaigns against the Muslims, culminating in a decisive victory in 740 . Constantine overcame an early civil war against his brother-in-law Artabasdos , made peace with
28280-496: The most powerful economic, cultural, and military force in the Mediterranean world . The term "Byzantine Empire" was only coined following the empire's demise; its citizens referred to the polity as the "Roman Empire" and to themselves as "Romans". Due to the imperial seat's move from Rome to Byzantium , the adoption of state Christianity , and the predominance of Greek instead of Latin , modern historians continue to make
28482-545: The name Constantinople after himself, where it was located in modern Istanbul . It subsequently became the capital of the empire for more than a thousand years, the later Eastern Roman Empire often being referred to in English as the Byzantine Empire , a term never used by the Empire, invented by German historian Hieronymus Wolf . His more immediate political legacy was that he replaced Diocletian's Tetrarchy with
28684-586: The new Abbasid Caliphate , campaigned successfully against the Bulgars, and continued to make administrative and military reforms. However, due to both emperors' support for the Byzantine Iconoclasm , which opposed the use of religious icons , they were later vilified by Byzantine historians; Constantine's reign also saw the loss of Ravenna to the Lombards , and the beginning of a split with
28886-431: The new title. By the spring of 310, Galerius was referring to both men as augusti. In 310, a dispossessed Maximian rebelled against Constantine while Constantine was away campaigning against the Franks. Maximian had been sent south to Arles with a contingent of Constantine's army, in preparation for any attacks by Maxentius in southern Gaul. He announced that Constantine was dead and took up the imperial purple. In spite of
29088-466: The newly-formed Arabic Rashidun Caliphate . By Heraclius' death in 641, the empire had been severely reduced economically as well as territorially—the loss of the wealthy eastern provinces had deprived Constantinople of three-quarters of its revenue. The next seventy-five years are poorly documented. Arab raids into Asia Minor began almost immediately, and the Byzantines resorted to holding fortified centres and avoiding battle at all costs; although it
29290-426: The north Italian plain sent Constantine embassies of congratulation for his victory. He moved on to Milan, where he was met with open gates and jubilant rejoicing. Constantine rested his army in Milan until mid-summer 312, when he moved on to Brixia ( Brescia ). Brescia's army was easily dispersed, and Constantine quickly advanced to Verona where a large Maxentian force was camped. Ruricius Pompeianus , general of
29492-596: The north without achieving great success. Constantius had become severely sick over the course of his reign and died on 25 July 306 in Eboracum . Before dying, he declared his support for raising Constantine to the rank of full Augustus. The Alamannic king Chrocus , a barbarian taken into service under Constantius, then proclaimed Constantine as augustus. The troops loyal to Constantius' memory followed him in acclamation. Gaul and Britain quickly accepted his rule; Hispania , which had been in his father's domain for less than
29694-522: The official propaganda of the period and are often one-sided; no contemporaneous histories or biographies dealing with his life and rule have survived. The nearest replacement is Eusebius 's Vita Constantini —a mixture of eulogy and hagiography written between 335 and circa 339 —that extols Constantine's moral and religious virtues. The Vita creates a contentiously positive image of Constantine, and modern historians have frequently challenged its reliability. The fullest secular life of Constantine
29896-468: The old family alliance between Maximian and Constantius and offer support to Maxentius' cause in Italy. Constantine accepted and married Fausta in Trier in summer 307. Constantine gave Maxentius his meagre support, offering Maxentius political recognition. Constantine remained aloof from the Italian conflict, however. Over the spring and summer of 307, he had left Gaul for Britain to avoid any involvement in
30098-491: The orator proclaims that Constantine experienced a divine vision of Apollo and Victory granting him laurel wreaths of health and a long reign. In the likeness of Apollo, Constantine recognised himself as the saving figure to whom would be granted "rule of the whole world", as the poet Virgil had once foretold. The oration's religious shift is paralleled by a similar shift in Constantine's coinage. In his early reign,
30300-514: The outset of his reign, Alexios faced a formidable attack from the Normans under Guiscard and his son Bohemund of Taranto , who captured Dyrrhachium and Corfu and laid siege to Larissa in Thessaly . Guiscard's death in 1085 temporarily eased the Norman problem. The following year, the Seljuq sultan died, and the sultanate was split due to internal rivalries. By his own efforts, Alexios defeated
30502-545: The panegyrist the opportunity to comment favourably on the similarities between father and son, and Eusebius remarked that Constantine was a "renewal, as it were, in his own person, of his father's life and reign". Constantinian coinage, sculpture, and oratory also show a tendency for disdain towards the "barbarians" beyond the frontiers. He minted a coin issue after his victory over the Alemanni which depicts weeping and begging Alemannic tribesmen, "the Alemanni conquered" beneath
30704-521: The patriarch Nicholas , the powerful Simeon I of Bulgaria , and other influential figures jockeyed for power. In 920, the admiral Romanos I used his fleet to secure power, crowning himself and demoting Constantine to the position of junior co-emperor. His reign, which brought peace with Bulgaria and successes in the east under the general John Kourkouas , was ended in 944 by the machinations of his sons, whom Constantine soon usurped in turn. Constantine's ineffectual sole rule has often been construed as
30906-412: The persecution. In his later writings, he attempted to present himself as an opponent of Diocletian's "sanguinary edicts" against the "Worshippers of God", but nothing indicates that he opposed it effectively at the time. Although no contemporary Christian challenged Constantine for his inaction during the persecutions, it remained a political liability throughout his life. On 1 May 305, Diocletian, as
31108-440: The phrase "Romans' rejoicing". There was little sympathy for these enemies; as his panegyrist declared, "It is a stupid clemency that spares the conquered foe." Following Galerius' recognition of Constantine as caesar, Constantine's portrait was brought to Rome, as was customary. Maxentius mocked the portrait's subject as the son of a harlot and lamented his own powerlessness. Maxentius, envious of Constantine's authority, seized
31310-475: The plot and warned Constantine, who put a eunuch in his own place in bed. Maximian was apprehended when he killed the eunuch and was offered suicide, which he accepted. Along with using propaganda, Constantine instituted a damnatio memoriae on Maximian, destroying all inscriptions referring to him and eliminating any public work bearing his image. The death of Maximian required a shift in Constantine's public image. He could no longer rely on his connection to
31512-410: The pope and Western Christian kingdoms, and he successfully handled the passage of the crusaders through his empire. In the East, Manuel suffered a major defeat in 1176 at the Battle of Myriokephalon against the Turks. These losses were quickly recovered, and in the following year Manuel's forces inflicted a defeat upon a force of "picked Turks". The Byzantine commander John Vatatzes , who destroyed
31714-605: The ports of southern Italy, he sent an expedition to Italy in 1155, but disputes within the coalition led to the eventual failure of the campaign. Despite this military setback, Manuel's armies successfully invaded the southern parts of the Kingdom of Hungary in 1167, defeating the Hungarians at the Battle of Sirmium . By 1168, nearly the whole of the eastern Adriatic coast lay in Manuel's hands. Manuel made several alliances with
31916-492: The quicker waters of the Rhone . He disembarked at Lugdunum ( Lyon ). Maximian fled to Massilia ( Marseille ), a town better able to withstand a long siege than Arles. It made little difference, however, as loyal citizens opened the rear gates to Constantine. Maximian was captured and reproved for his crimes. Constantine granted some clemency but strongly encouraged his suicide. In July 310, Maximian hanged himself . In spite of
32118-512: The rebels Carausius and Allectus . In spite of meritocratic overtones, the Tetrarchy retained vestiges of hereditary privilege, and Constantine became the prime candidate for future appointment as Caesar as soon as his father took the position. Constantine went to the court of Diocletian, where he lived as his father's heir presumptive . Constantine received a formal education at Diocletian's court, where he learned Latin literature, Greek, and philosophy. The cultural environment in Nicomedia
32320-441: The reconstituted empire would wield only regional power during its final two centuries of existence. Its remaining territories were progressively annexed by the Ottomans in perennial wars fought throughout the 14th and 15th centuries. The fall of Constantinople to the Ottomans in 1453 ultimately brought the empire to an end. Many refugees who had fled the city after its capture settled in Italy and throughout Europe, helping to ignite
32522-526: The region of the Dobruja over the next few years, where abandoned Roman-era forts were rebuilt and re-occupied. The region however fell back under Bulgarian control under the Cometopuli brothers in 986 and was held until c. 1001, when Byzantine control was re-established. Bănescu, however, considered that Dorostolon at least remained in Byzantine hands throughout. From the 1030s on, the region faced
32724-453: The rule of an emperor. The senate had its own identity but would become an extension of the emperor's court, becoming largely ceremonial. Constantine the Great Constantine I ( Latin : Flavius Valerius Constantinus ; 27 February c. 272 – 22 May 337), also known as Constantine the Great , was a Roman emperor from AD 306 to 337 and the first Roman emperor to convert to Christianity . He played
32926-451: The same heavenly sign and told him to make an army standard in the form of the labarum . Eusebius is vague about when and where these events took place, but it enters his narrative before the war begins against Maxentius. He describes the sign as Chi (Χ) traversed by Rho (Ρ) to form ☧, representing the first two letters of the Greek word ΧΡΙΣΤΟΣ (Christos). A medallion was issued at Ticinum in 315 which shows Constantine wearing
33128-503: The same type of war he had waged against Severus and Galerius: he occupied Rome and prepared for a siege. He still controlled Rome's Praetorian Guard , was well-stocked with African grain, and was surrounded on all sides by the seemingly impregnable Aurelian Walls . He ordered all bridges across the Tiber cut, reportedly on the counsel of the gods, and left the rest of central Italy undefended; Constantine secured that region's support without challenge. Constantine progressed slowly along
33330-427: The sixth anniversary of his reign, he approached the keepers of the Sibylline Books for guidance. The keepers prophesied that, on that very day, "the enemy of the Romans" would die. Maxentius advanced north to meet Constantine in battle. Maxentius' forces were still twice the size of Constantine's, and he organised them in long lines facing the battle plain with their backs to the river. Constantine's army arrived on
33532-422: The slip and returned with a larger force to oppose Constantine. Constantine refused to let up on the siege and sent only a small force to oppose him. In the desperately fought encounter that followed, Ruricius was killed and his army destroyed. Verona surrendered soon afterwards, followed by Aquileia , Mutina ( Modena ), and Ravenna . The road to Rome was now wide open to Constantine. Maxentius prepared for
33734-434: The speech made Galerius and Maximian irrelevant to Constantine's right to rule. Indeed, the orator emphasizes ancestry to the exclusion of all other factors: "No chance agreement of men, nor some unexpected consequence of favour, made you emperor," the orator declares to Constantine. The oration also moves away from the religious ideology of the Tetrarchy, with its focus on twin dynasties of Jupiter and Hercules . Instead,
33936-464: The summer of 305. From Bononia, they crossed the English Channel to Britain and made their way to Eboracum ( York ), capital of the province of Britannia Secunda and home to a large military base. Constantine was able to spend a year in northern Britain at his father's side, campaigning against the Picts beyond Hadrian's Wall in the summer and autumn. Constantius' campaign, like that of Septimius Severus before it, probably advanced far into
34138-581: The summer of 311, Maxentius mobilised against Constantine while Licinius was occupied with affairs in the East. He declared war on Constantine, vowing to avenge his father's "murder". To prevent Maxentius from forming an alliance against him with Licinius, Constantine forged his own alliance with Licinius over the winter of 311–312 and offered him his sister Constantia in marriage. Maximinus considered Constantine's arrangement with Licinius an affront to his authority. In response, he sent ambassadors to Rome, offering political recognition to Maxentius in exchange for
34340-491: The throne. Alexios was highly incompetent in the office, and with his mother Maria of Antioch 's Frankish background, his regency was unpopular. Eventually, Andronikos I Komnenos , a grandson of Alexios I, overthrew Alexios II in a violent coup d'état . After eliminating his potential rivals, he had himself crowned as co-emperor in September 1183. He eliminated Alexios II and took his 12-year-old wife Agnes of France for himself. Andronikos began his reign well; in particular,
34542-528: The title of emperor on 28 October 306. Galerius refused to recognize him but failed to unseat him. Severus was sent against Maxentius in April 307, but during the campaign, Severus' armies, previously under command of Maxentius' father Maximian, defected, and Severus was seized and imprisoned. Maximian, brought out of retirement by his son's rebellion, left for Gaul to confer with Constantine. He offered to marry his daughter Fausta to Constantine and elevate him to augustan rank. In return, Constantine would reaffirm
34744-614: The town quickly. Constantine ordered his troops not to loot the town and advanced into northern Italy. At the approach to the west of the important city of Augusta Taurinorum ( Turin , Italy), Constantine met a large force of heavily armed Maxentian cavalry. In the ensuing Battle of Turin Constantine's army encircled Maxentius' cavalry, flanked them with his own cavalry, and dismounted them with blows from his soldiers' iron-tipped clubs. Constantine's armies emerged victorious. Turin refused to give refuge to Maxentius' retreating forces, opening its gates to Constantine instead. Other cities of
34946-478: The tribes on the Roman frontiers —such as the Franks , the Alemanni , the Goths , and the Sarmatians —and resettled territories abandoned by his predecessors during the Crisis of the Third Century with citizens of Roman culture. Although Constantine lived much of his life as a pagan and later as a catechumen , he began to favour Christianity beginning in 312, finally becoming a Christian and being baptised by Eusebius of Nicomedia , an Arian bishop, although
35148-445: The two augusti fought against one another at the Battle of Cibalae , with Constantine being victorious. They clashed again at the Battle of Mardia in 317 and agreed to a settlement in which Constantine's sons Crispus and Constantine II , and Licinius' son Licinius Junior were made caesars . After this arrangement, Constantine ruled the dioceses of Pannonia and Macedonia and took residence at Sirmium , whence he could wage war on
35350-442: The unpopular Irene was overthrown by Nikephoros I ; he reformed the empire's administration but died in battle against the Bulgars in 811. Military defeats and societal disorder, especially the resurgence of iconoclasm, characterised the next eighteen years. Stability was somewhat restored during the reign of Theophilos ( r. 829–842 ), who exploited economic growth to complete construction programs, including rebuilding
35552-406: The west during the reign of Justinian I ( r. 527–565 ), who briefly reconquered much of Italy and the western Mediterranean coast . The appearance of plague and a devastating war with Persia exhausted the empire's resources; the early Muslim conquests that followed saw the loss of the empire's richest provinces— Egypt and Syria —to the Rashidun Caliphate . In 698, Africa was lost to
35754-408: The west, the warlord Odoacer deposed Romulus Augustulus in 476, killed his titular successor Julius Nepos in 480, and the office of western emperor was formally abolished. Through a combination of luck, cultural factors, and political decisions, the Eastern empire never suffered from rebellious barbarian vassals and was never ruled by barbarian warlords—the problems which ensured the downfall of
35956-401: The winter of 306–307. He drove them back beyond the Rhine and captured kings Ascaric and Merogais ; the kings and their soldiers were fed to the beasts of Trier Amphitheater in the adventus (arrival) celebrations which followed. Constantine began a major expansion of Trier. He strengthened the circuit wall around the city with military towers and fortified gates, and he began building
36158-422: The zenith of Byzantine learning , but while several works were compiled, they were largely intended to legitimise and glorify the emperor's Macedonian dynasty . His son and successor died young; under two soldier-emperors, Nikephoros II ( r. 963–969 ) and John I Tzimiskes ( r. 969–976 ), the Roman army claimed numerous military successes, including the conquest of Cilicia and Antioch , and
36360-487: Was Latin , and during his public speeches he needed Greek translators. In April 286, Diocletian declared Maximian , another colleague from Illyricum, his co-emperor. Each emperor would have his own court, his own military and administrative faculties, and each would rule with a separate praetorian prefect as chief lieutenant. Maximian ruled in the West, from his capitals at Mediolanum ( Milan , Italy) or Augusta Treverorum ( Trier , Germany), while Diocletian ruled in
36562-447: Was besieged in August 1068 and fell in April 1071 . About 1053, Constantine IX disbanded what the historian John Skylitzes calls the "Iberian Army", which consisted of 50,000 men, and it was turned into a contemporary Drungary of the Watch . Two other knowledgeable contemporaries, the former officials Michael Attaleiates and Kekaumenos , agree with Skylitzes that by demobilising these soldiers, Constantine did catastrophic harm to
36764-458: Was born on 27 February, c. AD 272 in the city of Naissus , a time where the unity of the Empire was threatened by the breakaway wars of the Palmyrene Empire . The city—which is modern day Niš in Serbia —was located in Dardania within Moesia Superior . His father was Flavius Constantius an Illyrian who was born in the same region, and a native of the province of Moesia. His original full name, as well as that of his father,
36966-469: Was built on his orders at the claimed site of Jesus' tomb in Jerusalem and was deemed the holiest place in all of Christendom . The papal claim to temporal power in the High Middle Ages was based on the fabricated Donation of Constantine . He has historically been referred to as the "First Christian Emperor", but while he did favour the Christian Church, some modern scholars debate his beliefs and even his comprehension of Christianity. Nevertheless, he
37168-560: Was captured. Alp Arslan treated him with respect and imposed no harsh terms on the Byzantines. In Constantinople a coup put in power Michael Doukas , who soon faced the opposition of Nikephoros Bryennios and Nikephoros III Botaneiates . By 1081, the Seljuks had expanded their rule over virtually the entire Anatolian plateau from Armenia in the east to Bithynia in the west, and had established their capital at Nicaea , just 90 kilometres (56 miles) from Constantinople. The Komnenian dynasty attained full power under Alexios I in 1081. From
37370-449: Was given credit for his predecessor's achievements. Basil I ( r. 867–886 ) continued Michael's policies. His armies campaigned with mixed results in Italy but defeated the Paulicians of Tephrike . His successor Leo VI ( r. 886–912 ) compiled and propagated a huge number of written works. These included the Basilika , a Greek translation of Justinian I's law-code which included over 100 new laws of Leo's devising;
37572-514: Was his fourth son, Manuel I Komnenos , who campaigned aggressively against his neighbours both in the west and east. In Palestine, Manuel allied with the Crusader Kingdom of Jerusalem and sent a large fleet to participate in a combined invasion of Fatimid Egypt . Manuel reinforced his position as overlord of the Crusader states, with his hegemony over Antioch and Jerusalem secured by agreement with Raynald , Prince of Antioch, and Amalric of Jerusalem . In an effort to restore Byzantine control over
37774-487: Was invaded annually, Anatolia avoided permanent Arab occupation. The outbreak of the First Fitna in 656 gave Byzantium breathing space, which it used wisely: some order was restored in the Balkans by Constans II ( r. 641–668 ), who began the administrative reorganisation known as the " theme system ", in which troops were allocated to defend specific provinces. With the help of the recently rediscovered Greek fire , Constantine IV ( r. 668–685 ) repelled
37976-404: Was killed in 326. Thus Constantine became the sole emperor of the Roman Empire. Diocletian had chosen Nicomedia in the East as his capital during the Tetrarchy —not far from Byzantium, well situated to defend Thrace, Asia, and Egypt, all of which had required his military attention. Constantine had recognised the shift of the empire from the remote and depopulated West to the richer cities of
38178-439: Was lost under Maxentius, recalling political exiles, and releasing Maxentius' imprisoned opponents. An extensive propaganda campaign followed, during which Maxentius' image was purged from all public places. He was written up as a "tyrant" and set against an idealised image of Constantine the "liberator". Eusebius is the best representative of this strand of Constantinian propaganda. Maxentius' rescripts were declared invalid, and
38380-497: Was marked by the theological dispute over Nestorianism , which was eventually deemed heretical , and by the formulation of the Codex Theodosianus law code. It also saw the arrival of Attila 's Huns , who ravaged the Balkans and exacted a massive tribute from the empire; Attila however switched his attention to the rapidly-deteriorating western empire , and his people fractured after his death in 453. After Leo I ( r. 457–474 ) failed in his 468 attempt to reconquer
38582-438: Was nonetheless a prominent member of the court: he fought for Diocletian and Galerius in Asia and served in a variety of tribunates ; he campaigned against barbarians on the Danube in 296 and fought the Persians under Diocletian in Syria in 297, as well as under Galerius in Mesopotamia in 298–299. By late 305, he had become a tribune of the first order, a tribunus ordinis primi . Constantine had returned to Nicomedia from
38784-406: Was not esteemed by the "soldier-emperors" who ruled from the frontiers or by the empire's population who, having been granted citizenship , considered themselves "Roman". Constantine extensively reformed the empire's military and civil administration and instituted the gold solidus as a stable currency. He favoured Christianity , which he had converted to in 312. Constantine's dynasty fought
38986-528: Was not yet a Christian. He probably judged it a more sensible policy than open persecution and a way to distinguish himself from the "great persecutor" Galerius. He decreed a formal end to persecution and returned to Christians all that they had lost during them. Constantine was largely untried and had a hint of illegitimacy about him; he relied on his father's reputation in his early propaganda, which gave as much coverage to his father's deeds as to his. His military skill and building projects, however, soon gave
39188-506: Was occupied by conflicts against two prominent generals, Bardas Skleros and Bardas Phokas , which ended in 989 with the former's death and the latter's submission. Between 1021 and 1022, following years of tensions, Basil II led a series of victorious campaigns against the Kingdom of Georgia , resulting in the annexation of several Georgian provinces to the empire. Basil's successors also annexed Bagratid Armenia in 1045. Importantly, both Georgia and Armenia were significantly weakened by
39390-417: Was open, fluid, and socially mobile; in it, Constantine could mix with intellectuals both pagan and Christian. He may have attended the lectures of Lactantius, a Christian scholar of Latin in the city. Because Diocletian did not completely trust Constantius—none of the Tetrarchs fully trusted their colleagues—Constantine was held as something of a hostage, a tool to ensure Constantius' best behavior. Constantine
39592-441: Was overthrown in 695 after attempting to exact too much from his subjects; over the next twenty-two years, six more rebellions followed in an era of political instability . The reconstituted caliphate sought to break Byzantium by taking Constantinople, but the newly crowned Leo III managed to repel the 717–718 siege , the first major setback of the Muslim conquests. Leo and his son Constantine V ( r. 741–775 ), two of
39794-440: Was proclaimed as augustus (emperor) by his army at Eboracum ( York , England). He eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324. Upon his ascension, Constantine enacted numerous reforms to strengthen the empire. He restructured the government, separating civil and military authorities. To combat inflation, he introduced
39996-413: Was proposed that a new Eastern capital should represent the integration of the East into the Roman Empire as a whole, as a centre of learning, prosperity, and cultural preservation for the whole of the Eastern Roman Empire. Among the various locations proposed for this alternative capital, Constantine appears to have toyed earlier with Serdica (present-day Sofia ), as he was reported saying that " Serdica
40198-445: Was put into a fury by the message; he almost set the portrait and messenger on fire. His advisers calmed him and argued that outright denial of Constantine's claims would mean certain war. Galerius was compelled to compromise: he granted Constantine the title "caesar" rather than "augustus" (the latter office went to Severus instead). Wishing to make it clear that he alone gave Constantine legitimacy, Galerius personally sent Constantine
40400-467: Was soon at war on many fronts. The Lombards , fearing the aggressive Avars , conquered much of northern Italy by 572. The Sasanian wars restarted that year, and continued until the emperor Maurice finally emerged victorious in 591; by that time, the Avars and Slavs had repeatedly invaded the Balkans , causing great instability. Maurice campaigned extensively in the region during the 590s, but although he managed to re-establish Byzantine control up to
40602-428: Was the norm. For this reason, he has been called the Byzantine Marcus Aurelius . During his twenty-five-year reign, John made alliances with the Holy Roman Empire in the West and decisively defeated the Pechenegs at the Battle of Beroia . He thwarted Hungarian and Serbian threats during the 1120s, and in 1130 he allied himself with Lothair III , the German Emperor against the Norman King Roger II of Sicily . In
40804-415: Was used adjectivally alongside terms such as "Empire of the Greeks" until the 19th century. It is now the primary term, used to refer to all aspects of the empire; some modern historians believe that, as an originally prejudicial and inaccurate term, it should not be used. As the historiographical periodizations of " Roman history ", " late antiquity ", and "Byzantine history" significantly overlap, there
