135-721: The city of Divriği was founded in the 9th century under Byzantine rule, but after the defeat of the Byzantines in the Battle of Manzikert (1071) it was occupied by Turkish tribes who settled the region. In this period the region of Anatolia came to be ruled by numerous competing beyliks ruled by local Turkish dynasties and offshoots of the Seljuk dynasty . In the 12th century, the Mengujekids or Mengücek dynasty controlled Divriği and other nearby cities such as Erzincan . During

270-462: 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

405-537: A bulbous finial similar to those at the top of minarets. Among the most notable examples is the minbar of the Mosque of Salih Tala'i , dated to 1300, which is also one of the earliest surviving minbars of this period. Another significant example is the minbar in the Mosque of Sultan al-Muayyad , from between 1415 and 1420. One of the finest minbars of the period is the Minbar of al-Ghamri (circa 1451), currently housed in

540-524: A canopy. From the subsequent Timurid period, the most important example is the minbar of the Mosque of Gowhar Shad in Mashhad , fabricated between 1336 and 1446. It shares the overall form of the minbar in Na'in and, like the latter, it also stands apart from other Iranian minbars in having a canopy. Its decoration is distinguished by a carpet-like geometric pattern filled with carvings of tendrils. In

675-467: 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

810-645: 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

945-464: 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

1080-502: A group of exceptional artists, necessary for the construction of the mosque and hospital, would have been present in the city around this time. He also notes that the cultural environment in this part of the world was highly diverse and dynamic during this period. Various groups of artisans and craftsmen likely travelled the region and moved from patron to patron, giving rise to an eclectic style of architecture that reflected influences from different places and traditions. The north portal of

1215-595: A large number in Venice. According to chronicler Niketas Choniates , a prostitute was even set up on the patriarchal throne. 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

1350-460: 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

1485-651: A line through the Adriatic Sea and south to Cyrene, Libya . 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

1620-620: A mix of marquetry , inlay , and wood carving . The only other minbar approaching, but not quite matching, the quality of the Almoravid minbar in Marrakesh is the minbar of the Qarawiyyin Mosque , also commissioned by Ali ibn Yusuf and completed in 1144. The other notable minbars produced after this, mostly found in present-day Morocco, generally imitate the style of the earlier Almoravid minbar. These later minbars include

1755-409: A mosque which adjoins the hospital with which it shares its southern, qibla wall. A mausoleum is attached to the hospital. The main entrance to the mosque is on the northern side and is marked by a tall portal which is celebrated for the quality and density of its high-relief stone carving. An entrance on the western side may be from a later date, as this façade of the mosque had collapsed and

1890-450: A small fleet of 100 ships to defend the capital, but other than that he was indifferent to the populace. 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

2025-513: A small tower with a seat or kiosk -like structure at its top and a staircase leading up to it. The bottom of the staircase often has a doorway or portal . In contrast to many Christian pulpits, the steps up to the minbar are usually in a straight line on the same axis as the seat. In some mosques, there is an elevated platform – dikka in Arabic or müezzin mahfil in Turkish – opposite

2160-417: 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

2295-660: A stone minbar to the Khanqah of Faraj ibn Barquq in 1483. This one is covered with geometric motifs carved to resemble the traditional style of wooden minbars. Ottoman minbars are distinguished in part by the shape of their canopy, where the traditional small dome is replaced with a tall, polygonal cone similar to the caps of Ottoman minarets. An exceptional early minbar is that of the Ahmed Pasha Mosque in Amasya , which has extensive finely-carved floral decoration. In

2430-528: A symbol of authority by the caliphs who followed him. The Umayyad caliph Mu'awiya I ( r.  661–680 ) heightened Muhammad's original minbar by increasing the number of steps from three to six, thus increasing its prominence. During the Umayyad period, the minbar was used by the caliphs or their representative governors to make important public announcements and to deliver the Friday sermon ( khutba ). In

2565-416: A symbol of authority. While minbars are roughly similar to church pulpits , they have a function and position more similar to that of a church lectern , being used instead by the imam for a wide range of readings and prayers. The minbar is located to the right of the mihrab , a niche in the far wall of the mosque that symbolizes the direction of prayer (i.e. towards Mecca ). It is usually shaped like

2700-517: A two-month siege on 29 May 1453. 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

2835-541: 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

2970-547: 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

3105-418: Is less dense and appears, in certain places, to be unfinished. The interior of the hospital consists of rooms and iwans placed around a covered courtyard with a small pool in the center. The hospital has a second story on its southern side which is reached by a staircase just inside the entrance. One of the rooms of the hospital was dedicated to serve as a dynastic tomb chamber. This room has a window opening to

3240-449: 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

3375-404: Is often assumed that Ahmadshāh and Tūrān Malik were married, there is no evidence, inscriptional or otherwise, to prove a matrimonial relationship between these two members of the extended Mengujekid royal family. The name of the chief architect is inscribed in the interior of both the mosque and the hospital and has been read as Khurramshāh ibn Mughīth al-Khilātī. The name indicates his origin in

3510-715: The Tactica , a military treatise; and the Book of the Eparch , which codified Constantinople's trading regulations. In non-literary contexts Leo was less successful: the empire lost in Sicily and against the Bulgarians , while he provoked theological scandal by marrying four times in an attempt to father a legitimate heir. The early reign of that heir, Constantine VII , was tumultuous, as his mother Zoe , his uncle Alexander ,

3645-754: The Almohad period later that century, it was moved to the Kutubiyya Mosque in the same city. It is housed today in the Badi Palace Museum . The richly-crafted minbar was fabricated in Cordoba and may thus provide some hint of the former style and craftsmanship of the Cordoba minbar, in addition to its other structural similarities. The decoration of this minbar, however, is more extravagant and sophisticated than any other surviving examples. It combines geometric and arabesque motifs executed in

3780-536: The Catalan Company ravaging the countryside and increasing resentment towards Constantinople. The situation became worse for Byzantium during the civil wars after Andronikos III died. A six-year-long civil war devastated the empire, allowing the Serbian ruler Stefan Dušan to overrun most of the empire's remaining territory and establish a Serbian Empire . In 1354, an earthquake at Gallipoli devastated

3915-706: The Council of Clermont and urged all those present to take up arms under the sign of the Cross and launch an armed pilgrimage to recover Jerusalem and the East from the Muslims. The response in Western Europe was overwhelming. Alexios was able to recover a number of important cities, islands and much of western Asia Minor. The Crusaders agreed to become Alexios' vassals under the Treaty of Devol in 1108, which marked

4050-684: The Council of Piacenza in 1095, envoys from Alexios spoke to Pope Urban II about the suffering of the Christians of the East and underscored that without help from the West, they would continue to suffer under Muslim rule. Urban saw Alexios' request as a dual opportunity to cement Western Europe and reunite the Eastern Orthodox Church with the Roman Catholic Church under his rule. On 27 November 1095, Urban called

4185-475: The Danube , he pushed his troops too far in 602—they mutinied, proclaimed an officer named Phocas as emperor, and executed Maurice. The Sasanians seized their moment and reopened hostilities ; Phocas was unable to cope and soon faced a major rebellion led by Heraclius . Phocas lost Constantinople in 610 and was soon executed, but the destructive civil war accelerated the empire's decline. Under Khosrow II ,

In the south and east were Anatolia, the Pontic Mountains and the Taurus - Anti-Taurus range, which served as passages for armies, while the Caucasus mountains lay between the Empire and its eastern neighbours. Roman roads connected

4455-636: The Empire of Trebizond , was created after Alexios I of Trebizond , commanding the Georgian expedition in Chaldia a few weeks before the sack of Constantinople, found himself de facto emperor and established himself in Trebizond. Of the three successor states, Epirus and Nicaea stood the best chance of reclaiming Constantinople. The Nicaean Empire struggled to survive the next few decades, however, and by

4590-583: The Great Mosque of Algiers , dated to around 1097, is more substantially preserved and resembles the presumed form of the Cordoba minbar. Its sides are decorated with square panels of vegetal and sometimes geometric motifs. The most important surviving minbar of this artistic tradition is the Almoravid minbar in Marrakesh , commissioned in 1137 by Ali ibn Yusuf and completed around 1145. During

4725-466: The Ilkhanid period (13th–14th centuries) include those in the Great Mosque of Na'in (1311) and in the prayer hall added by Uljaytu to the Great Mosque of Isfahan . Both are wooden structures, with the former's flanks decorated by rectangular panels with beveled motifs and the latter's flanks decorated by octagonal geometric motifs. The minbar in Na'in is also one of the few Iranian minbars topped by

4860-503: The Khanqah of Sultan Barsbay . This minbar takes the design of decorative geometric patterns slightly further by using curved lines instead of the usual straight lines to form its polygons. In the Maghreb , a number of wooden minbars have been preserved from the 10th to 15th centuries. The Great Mosque of Cordoba (in present-day Spain) hosted a famous minbar fabricated circa 975 on the orders of al-Hakam II . It has not survived to

4995-641: The Komnenian restoration , and Constantinople would remain the largest and wealthiest city in Europe until the 13th century. The empire was largely dismantled in 1204, following the Sack of Constantinople by Latin armies at the end of the Fourth Crusade ; its former territories were then divided into competing Greek rump states and Latin realms . Despite the eventual recovery of Constantinople in 1261,

5130-689: The Normans who arrived in Italy at the beginning of the 11th century. During a period of strife between Constantinople and Rome culminating in the East-West Schism of 1054 , the Normans advanced gradually into Byzantine Italy . Reggio , the capital of the tagma of Calabria, was captured in 1060 by Robert Guiscard , followed by Otranto in 1068. Bari , the main Byzantine stronghold in Apulia ,

5265-642: The Ottoman Baroque style , minbars were carved with eclectic motifs inspired by the European Baroque . Minbars were highly variable in style and size on the Indian subcontinent , but stone was the favoured material throughout the region. Wooden minbars may have been employed in earlier periods, but few or none have been preserved. Some of the minbars are merely a series of simple steps while others are very elaborate. Among other variations,

5400-556: The Ottoman Empire in 1453. During most of its existence, the empire remained 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

Having achieved stability in the West, Alexios could turn his attention to the severe economic difficulties and the disintegration of the empire's traditional defences. However, he still did not have enough manpower to recover the lost territories in Asia Minor and to the advance by the Seljuks. At

5670-633: The Renaissance . The fall of Constantinople is sometimes used to mark the dividing line between the Middle Ages and the early modern period . 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

5805-458: The Roman papacy . In 780, Empress Irene assumed power on behalf of her son Constantine VI . 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,

5940-677: The Umayyad Caliphate , but the empire subsequently stabilised under the Isaurian dynasty. The empire was able to expand once more under the Macedonian dynasty , experiencing a two-century-long renaissance . This came to an end in 1071, with the defeat by the Seljuk Turks at the Battle of Manzikert . Thereafter, periods of civil war and Seljuk incursion resulted in the loss of most of Asia Minor . The empire recovered during

6075-487: The caliphs who followed him, each of whom was officially the imam of the whole Muslim community . It is important to note that the title "Imam" was officially adopted by Imam Ali alone (The fourth Muslim caliph). The first three rulers of Muslims after the Prophet used the title "Caliph" for themselves. It eventually became standard for all Friday mosques and was used by the local imam, but it retained its significance as

6210-457: The sea walls of Constantinople , overhaul provincial governance, and wage inconclusive campaigns against the Abbasids. After his death, his empress Theodora , ruling on behalf of her son Michael III , permanently extinguished the iconoclastic movement; the empire prospered under their sometimes-fraught rule. However, Michael was posthumously vilified by historians loyal to the dynasty of his successor Basil I , who assassinated him in 867 and who

6345-527: The 11th to 15th centuries. The oldest surviving example is the Minbar of the Ibrahimi Mosque in Hebron , commissioned in 1091 under the Fatimids , originally for a shrine in Ascalon . It features decoration in geometric strapwork motifs and Arabic inscriptions. Among the most famous minbars was the Minbar of the al-Aqsa Mosque (also known as the Minbar of Saladin ) in Jerusalem , commissioned in 1168-69 by Nur ad-Din and signed by four different craftsmen. Prior to its destruction by arson in 1969, it

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. In the 540s, however, Justinian began to suffer reversals on multiple fronts. Taking advantage of Constantinople's preoccupation with

6615-408: The Arab efforts to capture Constantinople in the 670s , but suffered a reversal against the Bulgars , who soon established an empire in the northern Balkans . Nevertheless, he and Constans had done enough to secure the empire's position, especially as the Umayyad Caliphate was undergoing another civil war . Justinian II sought to build on the stability secured by his father Constantine but

6750-408: The Byzantine administration's policy of heavy taxation and abolishing of the levy. The weakening of Georgia and Armenia played a significant role in the Byzantine defeat at Manzikert in 1071. Basil II is considered among the most capable Byzantine emperors and his reign as the apex of the empire in the Middle Ages . By 1025, the date of Basil II's death, the Byzantine Empire stretched from Armenia in

6885-415: 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

SECTION 50

7020-432: The Empire. 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. The proclamations of the crowds of Constantinople, and the inaugurations of the patriarch from 457, would legitimise

7155-411: 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

7290-405: 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

7425-401: 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

7560-413: 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

7695-426: 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

7830-486: 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

7965-401: 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

8100-429: 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

8235-522: 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

8370-401: 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 )

8505-568: 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

8640-403: 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

8775-432: 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 ,

8910-581: The central Islamic lands, stone or marble minbars were occasionally produced at an early period, as with some examples in Mamluk Cairo, but they are generally characteristic of the later Ottoman period. Compared to the earlier traditions of wooden minbars, stone minbars were often simpler in their decoration. One of the few early marble minbars of Mamluk Cairo is found in the Aqsunqur Mosque in Cairo (circa 1347). Its marble surfaces are decorated with other stone materials of different colors inside an interlacing pattern formed by bands of marble. A marble minbar

9045-413: 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

9180-427: The city of Ahlat , known in medieval sources as al-Khilāt. According to inscriptions, the complex was significantly restored multiple times between the 15th and 19th centuries. More restoration work was carried out in the 20th century to counteract material deterioration and structural problems. In 2010 another major restoration process was decided. After several years of preparation, restoration work began in 2015 when

9315-439: 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

9450-447: 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

The geometric patterning of the decoration is further elaborated, using multi-pointed stars whose lines are extended into a wider complex pattern, with arabesques carved inside the various polygons. The canopy at the summit of the minbar was usually topped by

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

9855-433: 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

9990-537: 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

10125-533: 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

10260-496: 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"

10395-552: 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

10530-468: 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

10665-522: 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

10800-620: 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

10935-608: The finest Ottoman minbars, the main flanks are pierced with geometric openwork and arcades . The apogee of this style is exemplified by the minbar of the Selimiye Mosque in Edirne (circa 1574). The conical cap of this minbar is also covered with decorative tiles, a feature shared with the slightly earlier minbar of the Sokollu Mehmed Pasha Mosque . In later centuries, following the introduction of

11070-518: The first tender was held. The project halted and then resumed in 2017, but halted again in 2019 for financial reasons, though many stages of the process were already completed by then. A new tender was held in 2021 and in February 2022 work resumed on the last stages of the restoration process. The mosque was reopened to visitors in May 2024 after the project's completion. The building complex consists of

11205-584: 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,

11340-610: 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

11475-488: 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

11610-631: The last years of the Umayyad Caliphate, before its fall in 750, the Umayyads ordered minbars to be constructed for all the Friday mosques of Egypt and soon afterward this practice was extended to other Muslim territories. By the early Abbasid period (after 750), it had become standard in Friday mosques across all Muslim communities. Minbars thus quickly developed into a symbol of political and religious legitimacy for Muslim authorities. It

11745-667: 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

11880-595: The main mosques of their major cities. The oldest Islamic pulpit in the world to be preserved up to the present day is the minbar of the Great Mosque of Kairouan in Kairouan , Tunisia . It dates from around 860 or 862 CE, under the tenure of the Aghlabid governor Abu Ibrahim Ahmad , and was imported in whole or in part from Baghdad . It is an eleven-step staircase made of over 300 sculpted pieces of teak wood (a material imported from India ). Thanks to its age and

12015-418: 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

12150-592: 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,

12285-548: The minbar in Kairouan. When the minbar was modified in 985, some panels were replaced with panels of turned wood using a bow-drill technique. This is one of the earliest examples of this woodworking technique, which later became common in the fabrication of mashrabiyya s (wooden screens and balconies). The next oldest Maghrebi minbar to survive is that of the Great Mosque of Nedroma , dated to around 1086, but only some fragments of its original structure remain. The minbar of

12420-838: The minbar of the Kasbah Mosque in Marrakesh (circa 1189–1195), the minbar of the Mosque of the Andalusians following its Almohad renovation (circa 1203–1209), the minbar of the Great Mosque of Fes el-Jdid (circa 1276), the minbar of the Great Mosque of Taza (circa 1290–1300), and the minbar of the Bou Inania Madrasa in Fez (between 1350 and 1355). Even the much later minbar of the Mouassine Mosque in Marrakesh (between 1562 and 1573) continues to show imitations of

12555-529: The minbar where the assistant of the imam, the muezzin , stands during prayer. The muezzin recites the answers to the prayers of the imam where applicable. The first recorded minbar in the Islamic world was Muhammad's minbar in Medina , created in 629 CE (or between 628 and 631 CE). It consisted simply of two steps and a seat, resembling a throne . After Muhammad's death, this minbar continued to be used as

12690-457: The minbar's creation or including Qur'anic verses). In some cases they also featured delicate inlay work with ivory or mother-of-pearl . Many workshops created minbars that were assembled from hundreds of pieces held together using an interlocking technique and wooden pegs, but without glue or metal nails. Some of the best-documented minbars are those produced in the Levant and Egypt from

12825-780: The minbars of the Bengal Sultanate and the Gujarat Sultanate typically have canopies, while those of the Jaunpur Sultanate and Mughal Empire usually do not. One of the most elegant examples of the canopied type is the minbar in the Friday Mosque of Mandu in the Malwa region, dated to 1454, which has a dome in the local style upheld by curving brackets . In both the Gujarat and Malwa regions,

12960-667: The mosque gives the date of 626 AH (1228-9) and the name of its patron as Ahmadshāh ibn Sulaymān, who is one of the rulers of the Divriği branch of the Mengujekids. The inscription on the portal of the hospital describes the building as a dār al-shifā' ("house of healing") and ascribes its foundation to Tūrān Malik bint Fakhr al-Dīn Bahramshāh. Fakhr al-Dīn Bahramshāh is the best-known Mengujekid ruler whose reign, in Erzincan, lasted for nearly sixty years until his death in 1225. Although it

13095-665: The mosque. Byzantine Empire The Byzantine Empire , also referred to as the Eastern Roman Empire , was the continuation of the Roman Empire centred in Constantinople during late antiquity and the Middle Ages . The eastern half of the Empire survived the conditions that caused the fall of the West in the 5th century AD, and continued to exist until the fall of Constantinople to

13230-546: 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

13365-586: 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

13500-466: 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

13635-569: 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

13770-521: 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

13905-410: 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

14040-605: 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

14175-574: The predominance of Greek instead of Latin , modern historians continue to make 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

14310-464: The present day, but it was probably emulated by the later minbars in the Maghreb that have been preserved. Among the oldest surviving examples in the Maghreb, after the minbar of Kairouan, is the minbar of the Mosque of the Andalusians in Fez, which was originally constructed in 980 and is partly preserved today. Its original woodwork is carved with geometric motifs that appear inspired by those of

14445-441: 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

14580-572: The richness of its decoration, it is considered an important piece of historic Islamic art . Woodwork was the primary medium for the construction of minbars in much of the Middle East and North Africa up until the Ottoman period. These wooden minbars were in many cases very intricately decorated with geometric patterns and carved arabesques (vegetal and floral motifs), as well as with Arabic calligraphic inscriptions (often recording

14715-521: The royal platform are today on view in the museum of the Directorate of Pious Endowments in Ankara . The hospital is entered through its portal located on the western façade. Different in design from the north portal of the mosque, the hospital portal is framed by a monumental pointed arch and features a window in the center. The stone carving here is of the same quality as the main mosque portal but

14850-417: The rule of an emperor. The senate had its own identity but would become an extension of the emperor's court, becoming largely ceremonial. Minbar A minbar ( Arabic : منبر ; sometimes romanized as mimber ) is a pulpit in a mosque where the imam (leader of prayers ) stands to deliver sermons ( خطبة , khutbah ). It is also used in other similar contexts, such as in a Hussainiya where

14985-559: The same century, after the death of emir İshak, the dynasty was divided into two branches, with one ruling from Divriği while another branch ruled from Erzincan. The Mengujekids were related by marriage to the Seljuks of Konya and acknowledged them as their protectors and allies when the Sultanate of Rum, ruled from Konya , was at the height of its power. The Mengücek rulers were great patrons of arts, science, and literature. Art historian Doğan Kuban argues that this may account for why

15120-503: The same tradition. Iranian minbars typically have no canopy or dome at the top, distinguishing them from minbars in other regions. In Iran , Mesopotomia , and Anatolia , some wooden minbars preserved from the 11th and 12th centuries are carved with vegetal beveled-style motifs. Most other early minbars in Iran and Afghanistan were destroyed during the Mongol invasions of the 13th century. The most significant minbars preserved from

15255-465: The speaker sits and lectures the congregation. The word is a derivative of the Arabic root ن ب ر n-b-r ("to raise, elevate"); the Arabic plural is manābir ( Arabic : مَنابِر ). In Islam, the minbar is symbolically the seat of the imam who leads prayers in the mosque and delivers sermons . In the early years of Islam , this seat was reserved for the Islamic prophet Muhammad and later for

15390-479: The stone vaults above. The central bay of the mosque appears to have been left open to the sky, as is the case in other medieval Anatolian mosques which omit courtyards. Some of the original wooden furnishings of the mosque survive along its qibla wall, such as the shutters on the window opening to the tomb chamber within the hospital and its wooden minbar dated to 1243 and signed by the craftsman Ibrahīm ibn Ahmad al-Tiflīsī. Some carved wooden panels said to belong to

15525-548: 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,

15660-442: 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

15795-474: 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

15930-463: 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

16065-422: 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

16200-588: Was also constructed for the earlier Mosque of Ulmas al-Hajib (1329–1330). Only fragments of it have been preserved (kept at the Museum of Islamic Art in Cairo ), but they attest to some of the highest-quality stonework from the Mamluk period. The stone minbar of the Mosque of Sultan Hasan in Cairo (circa 1360) is relatively plain, though it has unusually ornate bronze doors. In the next century, Sultan Qaytbay gifted

16335-604: 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

16470-560: 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

16605-561: 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;

16740-581: 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

16875-546: 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

17010-564: 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

17145-406: 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

17280-506: 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

17415-473: Was one of the only major formal furnishings of a mosque and was therefore an important architectural feature in itself. More importantly, it was the setting for the weekly Friday sermon which, notably, usually mentioned the name of the current Muslim ruler over the community and included other public announcements of a religious or political nature. As a result, later Muslim rulers sometimes invested considerable expense in commissioning richly-decorated minbars for

17550-494: 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

17685-444: Was rebuilt at a later date when it was also strengthened by a round buttress on the north-western corner. A third entrance to the mosque is located on the eastern façade. This entrance appears to have served as a royal entrance which gave access to the raised wooden platform in the southeastern corner of the mosque's interior, reserved for the ruler and his entourage . The interior of the mosque consists of stone piers which support

17820-519: 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

17955-508: Was the most accomplished surviving example of Syrian craftsmanship in this woodworking tradition. Its sides were decorated with a tracery -like geometric pattern whose pieces were filled with carved arabesques. Its balustrades were made of turned wood assembled into a grille with more geometric designs, framed by Arabic inscriptions. Both the portal at the bottom and the kiosk-canopy at the top were crowned with muqarnas . In Mamluk Egypt (13th–16th centuries), minbars were crafted following

18090-766: 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

18225-415: 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
