190-547: Monothelitism , or monotheletism was a theological doctrine in Christianity that was proposed in the 7th century, but was ultimately rejected by the sixth ecumenical council. It held Christ as having only one will and was thus contrary to dyothelitism , the Christological doctrine accepted by most Christian denominations, which holds Christ as having two wills (divine and human). Historically, monothelitism
380-481: A human nature and a divine nature can co-exist in one person. The study of the inter-relationship of these two natures is one of the preoccupations of the majority tradition. Teachings about Jesus and testimonies about what he accomplished during his three-year public ministry are found throughout the New Testament . Core biblical teachings about the person of Jesus Christ may be summarized that Jesus Christ

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
760-430: A system of theological thought is the development of a method, one which can apply both broadly and particularly. Christian systematic theology will typically explore: Revelation is the revealing or disclosing, or making something obvious through active or passive communication with God, and can originate directly from God or through an agent, such as an angel . A person recognised as having experienced such contact
950-467: 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
1140-645: 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
1330-464: 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
1520-503: A discipline of Christian theology formulates an orderly, rational and coherent account of Christian faith and beliefs. Systematic theology draws on the foundational sacred texts of Christianity, while simultaneously investigating the development of Christian doctrine throughout history, particularly through the ecumenical councils of the early church (such as the First Council of Nicea ) and philosophical evolution. Inherent to
1710-522: A dispute over exactly how the human and divine natures of Christ actually exist within the person of Christ. The Christological definition of Chalcedon , as accepted by the Eastern Orthodox , Catholic , Anglican , Lutheran , and Reformed churches , is that Christ remains in two distinct natures, yet these two natures come together within his one hypostasis . More simply, Christ is known as "both fully human and fully Divine, one in being with
1900-542: 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
2090-809: A famous proclamation of faith among Christians since the 1st century, said, "You are the Christ, the Son of the living God." Most Christians now wait for the Second Coming of Christ when they believe he will fulfill the remaining Messianic prophecies . Christ is the English term for the Greek Χριστός ( Khristós ) meaning " the anointed one ". It is a translation of the Hebrew מָשִׁיחַ ( Māšîaḥ ), usually transliterated into English as Messiah .

Paul, another devoted monothelite, replied in a letter directing the pope to adhere to the doctrine of one will. Theodore, in turn, excommunicated

Christology was a fundamental concern from the First Council of Nicaea (325) until the Third Council of Constantinople (680). In this time period, the Christological views of various groups within the broader Christian community led to accusations of heresy , and, infrequently, subsequent religious persecution . In some cases,

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

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

Further, his second letter to Sergius was by and large orthodox. Maximus the Confessor, in his Disputation with Pyrrhus , interprets the statement "one will" as referring to the integrity of Christ's human will, in contrast to
3420-492: A point of reference for all other Christologies. Most of the major branches of Christianity— Catholicism , Eastern Orthodoxy , Anglicanism , Lutheranism , and Reformed —subscribe to the Chalcedonian Christological formulation, while many branches of Eastern Christianity— Syrian Orthodoxy , Assyrian Church , Coptic Orthodoxy , Ethiopian Orthodoxy , and Armenian Apostolicism —reject it. According to
3610-424: A position that Church unity should not be endangered by having any discussions or disputes over whether Christ had one energy or two. Sergius added that the doctrine of two energies could lead to the erroneous belief that Jesus has two conflicting wills. Honorius's reply in 635 endorsed that view that all discussions should cease and agreed that Jesus has only one will, not two conflicting wills, since Jesus assumed not
3800-498: A result of some earlier Christological controversies that were related to monophysitism as formulated by Eutyches (d. 456) and miaphysitism as formulated by non-Chalcedonian followers of Cyril of Alexandria (d. 444). Since the notion of Christ's one nature implied the oneness of his will, ecclesiastical and political elites of the Eastern Roman Empire tried during the 7th century to promote monothelitism as

This did not deny Christ human volition, but insisted that this volition could never be in opposition to the divine will; but the opponents of one will misinterpreted the doctrine as denying Christ any human volition whatever. Sophronius had died before the release of the new doctrine, and his replacement, Bishop Sergius of Jaffa, as Patriarch Abraham I of Jerusalem, approved the modified formula. Sergius died by

However, it was unclear whether the Chalcedonians should believe in Christ's human and divine energy and/or will as well as his human and divine nature because the ecumenical councils had made no ruling on that subject. A ruling for the new doctrine would provide common ground for the non-Chalcedonians and the Chalcedonians to come together, as

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

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

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
5130-455: A unifying doctrine that would reconcile divided Christian factions. In spite of strong imperial support, those attempts failed, and monothelitism was consequently rejected and denounced as heresy in 680–681 at the Third Council of Constantinople , the sixth ecumenical council. During the 5th century, some regions of the Church were thrown into confusion because of the debates that erupted over

In Christianity , the doctrine of the Trinity states that God is one being who exists, simultaneously and eternally , as a mutual indwelling of three Persons: the Father, the Son (incarnate as Jesus), and the Holy Spirit (or Holy Ghost). Since earliest Christianity, one's salvation has been very closely related to
5510-478: Is a further concept of infallibility, by suggesting that current biblical text is complete and without error, and that the integrity of biblical text has never been corrupted or degraded. Historians note, or claim, that the doctrine of the Bible's infallibility was adopted hundreds of years after the books of the Bible were written. The authority of the Bible can also be linked to the principle of sola scriptura ,
5700-533: Is a trinity in God's single being, the meaning of which has always been debated. This mysterious "Trinity" has been described as hypostases in the Greek language ( subsistences in Latin ), and "persons" in English. Nonetheless, Christians stress that they only believe in one God. Most Christian churches teach the Trinity, as opposed to Unitarian monotheistic beliefs. Historically, most Christian churches have taught that

The Father is said to be in unique relationship with his only begotten ( monogenes ) son, Jesus Christ , which implies an exclusive and intimate familiarity: "No one knows the Son except the Father, and no one knows the Father except the Son and any one to whom the Son chooses to reveal him." In Christianity, God

The two are thus united without separation, without confusion, and without alteration, and with each having a particularity. Miaphysitism is the christological doctrine of the Oriental Orthodox churches. Nevertheless, the resultant debates led

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

A similar translation appears in the New English Bible , in

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
7030-449: 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
7220-650: Is often called a prophet . Christianity generally considers the Bible as divinely or supernaturally revealed or inspired. Such revelation does not always require the presence of God or an angel. For instance, in the concept which Catholics call interior locution , supernatural revelation can include just an inner voice heard by the recipient. Thomas Aquinas (1225–1274) first described two types of revelation in Christianity: general revelation and special revelation . The Bible contains many passages in which

The word is in fact used as a title , hence its common reciprocal use Christ Jesus , meaning Jesus the Anointed One or Jesus the Messiah. Followers of Jesus became known as Christians because they believed that Jesus was the Christ, or Messiah, prophesied about in the Old Testament , or Tanakh . The Christological controversies came to
7600-571: Is the creator and preserver of the universe . God is the sole ultimate power in the universe but is distinct from it. The Bible never speaks of God as impersonal. Instead, it refers to him in personal terms – who speaks, sees, hears, acts, and loves. God is understood to have a will and personality and is an all powerful , divine and benevolent being. He is represented in Scripture as being primarily concerned with people and their salvation. Many Reformed theologians distinguish between

The doctrine of the Trinity identifies Jesus of Nazareth as God the Son, united in essence but distinct in person with regard to God the Father and God the Holy Spirit (the first and third persons of the Trinity). God the Son is co-eternal with God the Father (and the Holy Spirit), both before Creation and after

Around 400, Jerome produced the Vulgate , a definitive Latin edition of the Bible, the contents of which, at the insistence of the Bishop of Rome , accorded with the decisions of the earlier synods.

For Jews and Muslims , the idea of God as a trinity is heretical – it is considered akin to polytheism .

15010-475: The Father has a special role in his relationship with the person of the Son, where Jesus is believed to be his Son and his heir. According to the Nicene Creed , the Son (Jesus Christ) is "eternally begotten of the Father", indicating that their divine Father-Son relationship is not tied to an event within time or human history. See Christology . The Bible refers to Christ, called " The Word " as present at
15200-467: The Father". This position was opposed by the Monophysites who held that Christ possesses one nature only. The term Monophysitism of which Eutychianism is one type, held that the human and divine natures of Christ were fused into one new single ( mono ) nature. As described by Eutyches , his human nature was "dissolved like a drop of honey in the sea", and therefore his nature is really divine. This
15390-453: The Father's relationship with humanity is as a father to children—in a previously unheard-of sense—and not just as the creator and nurturer of creation, and the provider for his children, his people. Thus, humans, in general, are sometimes called children of God . To Christians, God the Father's relationship with humanity is that of Creator and created beings, and in that respect he is the father of all. The New Testament says, in this sense, that
15580-578: The LORD" (for example, 1 Kgs 12:22–24;1 Chr 17:3–4; Jer 35:13; Ezek 2:4; Zech 7:9 ; etc.). The Second Epistle of Peter claims that "no prophecy of Scripture ... was ever produced by the will of man, but men spoke from God as they were carried along by the Holy Spirit" The Second Epistle of Peter also implies that Paul's writings are inspired ( 2 Pet 3:16 ). Many Christians cite a verse in Paul's letter to Timothy, 2 Timothy 3:16–17, as evidence that "all scripture
15770-580: The Mongol invasion also gave Nicaea a temporary respite from Seljuk attacks, allowing it to concentrate on the Latin Empire to its north. The Empire of Nicaea, founded by the Laskarid dynasty , managed to recapture Constantinople in 1261 and defeat Epirus . This led to a short-lived revival of Byzantine fortunes under Michael VIII Palaiologos , but the war-ravaged empire was ill-equipped to deal with
15960-587: The Normans were driven out of Greece, in 1186 the Vlachs and Bulgars began a rebellion that led to the formation of the Second Bulgarian Empire . The internal policy of the Angeloi was characterised by the squandering of the public treasure and fiscal maladministration. Imperial authority was severely weakened, and the growing power vacuum at the centre of the empire encouraged fragmentation. There
16150-401: The Patriarchs of Constantinople and Antioch were present in person. With the exception of two individuals, it condemned the monothelite doctrine as one that diminished the fullness of Christ's humanity and asserted dyothelitism to be the true doctrine, with Christ possessing "two natural wills and two natural energies, without division, alteration, separation or confusion". It also anathematised
16340-680: 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
16530-491: The Son and the Holy Spirit are still seen as originating from God the Father. The New Testament does not have the term "Trinity" and nowhere discusses the Trinity as such. Some emphasize, however, that the New Testament does repeatedly speak of the Father, the Son, and the Holy Spirit to "compel a trinitarian understanding of God." The doctrine developed from the biblical language used in New Testament passages such as
16720-470: 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
16910-510: The Trinity teaches the unity of Father , Son , and Holy Spirit as three persons in one Godhead . The doctrine states that God is the Triune God, existing as three persons , or in the Greek hypostases , but one being. Personhood in the Trinity does not match the common Western understanding of "person" as used in the English language—it does not imply an "individual, self-actualized center of free will and conscious activity." To
17100-696: The Trinity, is a mark of Catholicism , Eastern and Oriental Orthodoxy as well as other prominent Christian sects arising from the Protestant Reformation , such as Anglicanism , Methodism , Lutheranism , Baptist , and Presbyterianism . The Oxford Dictionary of the Christian Church describes the Trinity as "the central dogma of Christian theology". This doctrine contrasts with Nontrinitarian positions which include Unitarianism , Oneness and Modalism . A small minority of Christians hold non-trinitarian views, largely coming under
17290-481: 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
17480-610: 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
17670-401: 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
17860-596: 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
18050-522: 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
18240-590: 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 )
18430-401: The ancients, personhood "was in some sense individual, but always in community as well." Each person is understood as having the one identical essence or nature, not merely similar natures. Since the beginning of the 3rd century the doctrine of the Trinity has been stated as "the one God exists in three Persons and one substance , Father, Son, and Holy Spirit." Trinitarianism, belief in
18620-537: The areas most likely to be lost to the empire were the regions that were in favour of Monophysitism, and who considered the religious hierarchy at Constantinople to be heretics only interested in crushing their faith. In these provinces, the non-Chalcedonians were far more numerous than the Chalcedonians. In Egypt for instance, some 30,000 Greeks of Chalcedonian persuasion were ranged against some five million Coptic non-Chalcedonians. Meanwhile, Syria and Mesopotamia were divided between Nestorianism and Jacobitism, while
18810-568: 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
19000-526: The authors claim divine inspiration for their message or report the effects of such inspiration on others. Besides the direct accounts of written revelation (such as Moses receiving the Ten Commandments inscribed on tablets of stone), the Prophets of the Old Testament frequently claimed that their message was of divine origin by prefacing the revelation using the following phrase: "Thus says
19190-496: The baptismal formula in Matthew 28:19 and by the end of the 4th century it was widely held in its present form. In many monotheist religions, God is addressed as the father, in part because of his active interest in human affairs, in the way that a father would take an interest in his children who are dependent on him and as a father, he will respond to humanity, his children, acting in their best interests. In Christianity, God
19380-411: The beginning of God's creation., not a creation himself, but equal in the personhood of the Trinity. In Eastern Orthodox theology, God the Father is the "principium" ( beginning ), the "source" or "origin" of both the Son and the Holy Spirit, which gives intuitive emphasis to the threeness of persons; by comparison, Western theology explains the "origin" of all three hypostases or persons as being in
19570-403: 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
19760-495: 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 ,
19950-731: The chief representatives of the discredited doctrine, including Pope Honorius. The churches condemned at Constantinople included the Oriental Orthodox Churches and the Maronite Church, but the Oriental Orthodox have denied that they ever held the monothelite view and describe their own Christology as Miaphysite , and the Maronites accept the Chalcedonian formula since they are in communion with
20140-469: 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
20330-742: The claim that by scripture alone that the authority of the Bible is more important than the authority of the Church. The content of the Protestant Old Testament is the same as the Hebrew Bible canon , with changes in the division and order of books, but the Catholic Old Testament contains additional texts, known as the deuterocanonical books . Protestants recognize 39 books in their Old Testament canon, while Roman Catholic and Eastern Christians recognize 46 books as canonical. Both Catholics and Protestants use
20520-556: The concept of a triune God, although the Trinitarian doctrine was not formalized until the 4th century. At that time, the Emperor Constantine convoked the First Council of Nicaea , to which all bishops of the empire were invited to attend. Pope Sylvester I did not attend but sent his legate . The council, among other things, decreed the original Nicene Creed. For most Christians, beliefs about God are enshrined in
20710-525: The controversy was all due to Sergius and that the patriarch had pressured him to give his unwilling approval to the Ecthesis . This state of schism remained for the next few years. The death of Heraclius in 641 had thrown the political situation in Constantinople into chaos, and his young grandson Constans II (641–668) succeeded him. Meanwhile, in Africa, a monk, Maximus the Confessor , carried on
20900-550: 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
21090-504: 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
21280-444: The divine nature, which gives intuitive emphasis to the oneness of God's being. Christology is the field of study within Christian theology which is primarily concerned with the nature, person, and works of Jesus Christ , held by Christians to be the Son of God . Christology is concerned with the meeting of the human ( Son of Man ) and divine ( God the Son or Word of God ) in the person of Jesus . Primary considerations include
21470-557: The doctrine began to subside, and soon, former supporters were busy finding flaws and inconsistencies in the proposal. Soon, Sergius and Heraclius abandoned it as a doctrine. However, Sergius and the emperor refused to give up. Three years later, the patriarch came up with a slightly-modified formula, which Heraclius released as the Ecthesis in 638. The edict was considered to be the official response to Sophronius's letter. It forbade all mention of Christ possessing one or two energies; instead, it now proclaimed that Christ has two natures but
21660-466: The doctrine of Trinitarianism , which holds that the three persons of God together form a single God. The Trinitarian view emphasizes that God has a will and that God the Son has two wills, divine and human, though these are never in conflict (see Hypostatic union ). However, this point is disputed by Oriental Orthodox Christians, who hold that God the Son has only one will of unified divinity and humanity (see Miaphysitism ). The Christian doctrine of
21850-443: The doctrine of the Trinity than with the Christological debates. There are over 40 places in the New Testament where Jesus is given the title "the Son of God", but scholars don't consider this to be an equivalent expression. "God the Son" is rejected by anti-trinitarians , who view this reversal of the most common term for Christ as a doctrinal perversion and as tending towards tritheism . Matthew cites Jesus as saying, "Blessed are
22040-566: The doctrine of the two wills of Christ. He was concerned that for the sake of ecclesiastical unity, doctrinal expressions were being compromised. For the first few years, Patriarch Sergius of Constantinople managed to keep him silent, but when Sophronius was appointed as Patriarch of Jerusalem in 634, he used his newfound position of authority to challenge the validity of the doctrine of monoenergism. Determined to prevent that formidable challenge to his Christological compromise, Sergius wrote to Pope Honorius I (625–638) at Rome to ask him to endorse
22230-475: 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
22420-433: 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
22610-544: The emperor asserted that the energy, or the active force, of Christ was single. That doctrine of monoenergism was the precursor of monotheletism. Heraclius's interest then focused on Armenia, and it was probably then that the emperor decided to use monoenergism as a political weapon to reconcile the Non-Chalcedonian Church of Armenia with the Imperial Church. To help bring that about, a synod
22800-480: 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
22990-533: 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
23180-496: 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"
23370-499: 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
23560-468: 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
23750-486: The end of 638, and his replacement, Pyrrhus , was also a devoted monothelite and a close friend of Heraclius. The two remaining patriarchs in the East also gave their approval to the doctrine now referred to as monothelitism and so it looked as if Heraclius would finally heal the divisions in the imperial church. Unfortunately, he had not counted on the popes at Rome . During the same year, 638, Pope Honorius I had died as well. His successor Pope Severinus (640) condemned
23940-522: 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
24130-615: 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
24320-467: The fallen human will, which seeks diverse and contradictory goods. The Third Council of Constantinople posthumously anathematised Honorius as a heretic: "And with these we define that there shall be expelled from the holy Church of God and anathematized Honorius who was some time Pope of Old Rome, because of what we found written by him to Sergius, that in all respects he followed his view and confirmed his impious doctrines" (13th session) and "To Honorius,
24510-636: 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,
24700-607: 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
24890-495: The heading of Unitarianism . Most, if not all, Christians believe that God is spirit, an uncreated, omnipotent , and eternal being, the creator and sustainer of all things, who works the redemption of the world through his Son, Jesus Christ. With this background, belief in the divinity of Christ and the Holy Spirit is expressed as the doctrine of the Trinity , which describes the single divine ousia (substance) existing as three distinct and inseparable hypostases (persons):
25080-431: 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
25270-458: The heretic, anathema!" (16th session). However, Pope Leo II's letter of confirmation of the Council interprets the council as intending to criticise Honorius not for error of belief but for "imprudent economy of silence". Leo's letter stated: "We anathematize the inventors of the new error, that is, Theodore, Sergius,... and also Honorius, who did not attempt to sanctify this Apostolic Church with
25460-726: 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
25650-418: 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
25840-592: 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,
26030-546: 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
26220-496: 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
26410-414: The nature of God is a mystery , something that must be revealed by special revelation rather than deduced through general revelation . Christian orthodox traditions (Catholic, Eastern Orthodox, and Protestant) follow this idea, which was codified in 381 and reached its full development through the work of the Cappadocian Fathers . They consider God to be a triune entity, called the Trinity, comprising
26600-435: The nature of Jesus Christ. Although the Church had already determined that Christ is the son of God, his exact nature remained open to debate. The Church had declared heretical the notion that Jesus is not fully divine in the 4th century (see First Council of Nicaea ), during the debates over Arianism , and had declared that he is God the Son who became human. However, in arguing that he is both God and man, there then emerged
26790-586: 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
26980-466: 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
27170-483: The non-Chalcedonians could agree that Jesus has two natures if he has only one will, and some Chalcedonians could agree that Jesus has one will if he has two natures. Patriarch Sergius I of Constantinople was the driving force behind this doctrine, with the full blessing of Emperor Heraclius. Coming to the imperial throne in 610, the patriarch had long since converted the emperor to the new doctrine as by 622, Heraclius had communicated with Bishop Paul of Armenia where
27360-514: 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
27550-407: The pains and temptations of a mortal man, yet he did not sin. As fully God, he defeated death and rose to life again. Scripture asserts that Jesus was conceived, by the Holy Spirit, and born of his virgin mother Mary without a human father. The biblical accounts of Jesus's ministry include miracles , preaching, teaching, healing , Death , and resurrection . The apostle Peter, in what has become
27740-521: 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
27930-474: The patriarch in 649 and declared Paul a heretic. Constans II was only 17 and was indifferent to the religious debates convulsing the Church. However, he was concerned about the effect that the debate had on the Roman Empire and so he issued an imperial edict , the Type of Constans . The edict made it illegal to discuss in any manner Christ possessing either one or two wills or one or two energies. He declared that
28120-481: The patriarchs, including the popes, remaining silent throughout the remainder of his reign. After Constans's death in 668, the throne passed to his son Constantine IV . Pope Vitalian (657–672), who had hosted the visit of Constans II to Rome in 663, almost immediately declared himself for the doctrine of the two wills of Christ. In response, Patriarch Theodore I of Constantinople and Macarius, Patriarch of Antioch, both pressed Constantine to take some measures against
28310-535: The peacemakers, for they will be called sons of God (5:9)." The gospels go on to document a great deal of controversy over Jesus being the Son of God, in a unique way. The book of the Acts of the Apostles and the letters of the New Testament, however, record the early teaching of the first Christians– those who believed Jesus to be both the Son of God, the Messiah, a man appointed by God, as well as God himself. This
28500-410: 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
28690-459: The pope. Constantine, however, decided to let the monothelite question be decided entirely by a church council. He asked if the pope (now Pope Agatho , 678–681) would be willing to send delegates to an ecumenical council to be held at Constantinople so that the question could be firmly ended. Pope Agatho agreed but first held a preliminary synod at Rome 680 to obtain the opinion of the western theologians. Other synods were also held at Milan and at
28880-605: 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
29070-493: 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
29260-549: The recovered monophysite (also referred to as "non-Chalcedonian" for rejecting of that particular council) provinces of Syria and Egypt. In 629, a meeting took place between the emperor and Athanasius the Jacobite at Hierapolis . An agreement was struck in which the Jacobites were to return to the Imperial Church on the basis of the single energy doctrine, and Athanasius was to be made Patriarch of Antioch . In 630, Bishop Cyrus
29450-510: The religion of Armenia was wholly Cyrilline Non-Chalcedonian, and Palestine fully adhered to Chalcedonianism. Consequently, the Monothelite teaching emerged as a compromise position. The Byzantine emperor Heraclius tried to unite all of the various factions within the empire with this new formula that was more inclusive and more elastic. That approach was needed to win over the non-Chalcedonians since they already believed that Christ has
29640-422: The same 27-book New Testament canon. Early Christians used the Septuagint , a Koine Greek translation of the Hebrew scriptures. Christianity subsequently endorsed various additional writings that would become the New Testament. In the 4th century a series of synods , most notably the Synod of Hippo in AD 393, produced a list of texts equal to the 46-book canon of the Old Testament that Catholics use today (and
29830-501: The study of Christian theology for a variety of reasons, such as in order to: Christian theology has permeated much of non-ecclesiastical Western culture , especially in pre-modern Europe, although Christianity is a worldwide religion . Christian theology varies significantly across the main branches of Christian tradition: Catholic , Orthodox and Protestant . Each of those traditions has its own unique approaches to seminaries and ministerial formation. Systematic theology as
30020-498: The teaching of Apostolic tradition, but by profane treachery permitted its purity to be polluted." Christian theology Christian theology is the theology – the systematic study of the divine and religion – of Christian belief and practice. It concentrates primarily upon the texts of the Old Testament and of the New Testament , as well as on Christian tradition . Christian theologians use biblical exegesis , rational analysis and argument. Theologians may undertake
30210-529: The three "Persons"; God the Father , God the Son , and God the Holy Spirit , described as being "of the same substance" ( ὁμοούσιος ). The true nature of an infinite God, however, is commonly described as beyond definition, and the word 'person' is an imperfect expression of the idea. Some critics contend that because of the adoption of a tripartite conception of deity, Christianity is a form of tritheism or polytheism . This concept dates from Arian teachings which claimed that Jesus, having appeared later in
30400-491: 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,
30590-442: 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
30780-413: The very idea of family, wherever it appears, derives its name from God the Father, and thus God himself is the model of the family. However, there is a deeper "legal" sense in which Christians believe that they are made participants in the special relationship of Father and Son, through Jesus Christ as his spiritual bride . Christians call themselves adopted children of God. In the New Testament, God
30970-452: The vitiated human nature, tainted by Adam's fall, but human nature as it existed prior to Adam's fall. In the meantime the epistola synodica of Sophronius appeared, the outcome of the Synod of Cyprus. It attempted to show that the new doctrine was inconsistent with orthodoxy . Sophronius declared that it was nothing more than a bastardised form of monophysitism, which went against the hard-fought achievements at Chalcedon. Suddenly, support for
31160-406: 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
31350-408: 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
31540-443: The whole controversy was to be forgotten: "the scheme which existed before the strife arose shall be maintained, as it would have been if no such disputation had arisen". However, he would soon discover that the controversy would not die down. In Rome and the West, opposition to monothelitism was reaching fever pitch, and the Type of Constans did nothing to defuse the situation but indeed made it worse by implying that either doctrine
31730-574: The word inspiration , which has the Latin root inspīrāre - "to blow or breathe into". Christianity generally regards the agreed collections of books known as the Bible as authoritative and as written by human authors under the inspiration of the Holy Spirit . Some Christians believe that the Bible is inerrant (totally without error and free from contradiction, including the historical and scientific parts) or infallible (inerrant on issues of faith and practice but not necessarily on matters of history or science). Some Christians infer that
31920-422: 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
32110-530: Was and forever is fully God (divine) and fully human in one sinless person at the same time, and that through the death and resurrection of Jesus , sinful humans can be reconciled to God and thereby are offered salvation and the promise of eternal life via his New Covenant . While there have been theological disputes over the nature of Jesus, Christians believe that Jesus is God incarnate and " true God and true man " (or both fully divine and fully human). Jesus, having become fully human in all respects, suffered
32300-423: Was as good as the other. Theodore planned the Lateran Council of 649 to condemn the Ecthesis but died before he could convene it, which his successor, Pope Martin I (649–653), did. The council condemned the Ecthesis but also the Type . After the synod, Pope Martin wrote to Constans to inform him of its conclusions and to require him to condemn both the monothelite doctrine and his own Type . However, Constans
32490-447: 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
32680-560: 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
32870-416: Was closely related to monoenergism , a theological doctrine that holds Jesus Christ as having only one energy . Both doctrines were at the center of Christological disputes during the 7th century. Monothelitism is from Greek : μονοθελητισμός , romanized : monothelētismós , lit. 'doctrine of one will'. Theological notions related to the oneness of Christ's will emerged as
33060-400: Was fully divine and also human. What it did not do was make clear how one person could be both divine and human, and how the divine and human were related within that one person. This led to the Christological controversies of the 4th and 5th centuries of the Christian era. The Chalcedonian Creed did not put an end to all Christological debate, but it did clarify the terms used and became
33250-449: 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;
33440-410: Was held in 622 at Theodosiopolis , called the Synod of Garin, where monoenergism was discussed. Over the next few years Heraclius was preoccupied with his prosecution of the war against the Sassanids , but by 626, he had issued a decree to Arcadius, Bishop of Cyprus , requesting him to teach the doctrine of "one hegumenic energy". By all accounts, that was met with notable success, particularly as there
33630-514: 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
33820-427: Was imprisoned and tortured before he was condemned for breaking the imperial commands and banished before he died from his treatment at the hands of the emperor. The emperor continued to persecute any who spoke out against monothelitism, including Maximus the Confessor and a number of his disciples. Maximus lost his tongue and his right hand in an effort to have him recant. Nevertheless, his brutality had an effect, with
34010-487: 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
34200-407: Was made Patriarch of Alexandria , who soon won over another non-Chalcedonian group. Very soon, three of the five patriarchates (Constantinople, Antioch and Alexandria) were teaching Christ's "one theandric energy". Not everyone was convinced, particularly a monk of Palestine named Sophronius , who believed that there was something unsound in the doctrine and so became the champion of dyothelitism,
34390-497: 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
34580-406: 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
34770-478: Was not the sort of emperor to take such a rebuke of imperial authority lightly. Even while the Lateran Synod was sitting, Olympius arrived as the new exarch of Ravenna , with instructions to ensure that the Type was followed in Italy and to use whatever means necessary to ensure that the Pope adhered to it. He was unable to complete his mission and soon died, but his successor, Theodore I Calliopas , seized Pope Martin and abducted him to Constantinople, where he
34960-506: 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
35150-441: 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
35340-467: 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
35530-435: Was that the one God exists in three persons (Father, Son, and Holy Spirit); in particular it was affirmed that the Son was homoousios (of one substance) with the Father. The Creed of the Nicene Council made statements about the full divinity and full humanity of Jesus, thus preparing the way for discussion about how exactly the divine and human come together in the person of Christ (Christology). Nicaea insisted that Jesus
35720-428: 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
35910-408: Was then a large colony of Armenians on the island, which encouraged Heraclius to attempt to seek a wider approval of his compromise. In 626, he asked Patriarch Sergius to approach Cyrus, Bishop of Phasis , to secure his cooperation. With the successful conclusion to the Persian War, Heraclius could devote more time to promoting his compromise, which was now more urgent because of the administration of
36100-415: 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
