145-538: Ioannina is first definitely mentioned in a 1020 decree by the Byzantine emperor Basil II , but it clearly existed for several centuries before. Traditionally, the foundation and first fortification of the city have been placed in the 6th century, when the historian Procopius ( De Aedificiis , IV.1.39–42) records the construction of a new, "well-fortified" city by the Byzantine emperor Justinian I ( r.  527–565 ) for

290-633: 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 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

435-456: 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

580-463: 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

725-626: 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

870-554: A cousin of the Byzantine emperors Isaac II Angelos and Alexios III Angelos . At first, Michael allied with Boniface of Montferrat , but having lost the Morea ( Peloponnese ) to the Franks at the battle of the Olive Grove of Koundouros , he went to Epirus , where he considered himself the Byzantine governor of the old province of Nicopolis and revolted against Boniface. Epirus soon became

1015-577: 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

1160-504: 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

1305-632: 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

1450-461: A name in use at the time. The Despotate was centred on the region of Epirus , encompassing also Albania and the western portion of Greek Macedonia and also included Thessaly and western Greece as far south as Nafpaktos . Through a policy of aggressive expansion under Theodore Komnenos Doukas the Despotate of Epirus also briefly came to incorporate central Macedonia , with the establishment of

1595-486: A new wall in front. The interval was filled up with rubble or provided with arched galleries, forming a large terraced surface on top on which cannon could be installed. The castle is located on the southeastern corner of the modern city, on top a rocky promontory jutting into Lake Pamvotis . The castle is dominated by its two citadels, already established by the late 11th century as recorded in Anna Komnene 's Alexiad :

1740-450: 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

1885-417: 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

2030-593: 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 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

2175-510: 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

2320-531: 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

2465-532: 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

2610-611: Is the so-called "Treasury" (Θησαυροφυλάκιο) to the north, a square building of unidentified use. A domed space adjacent to it was later converted into the small church of the Holy Unmercenaries (Άγιοι Ανάργυροι). The Treasury was restored in 1989–90 and houses an exhibition on the history and methods of silversmithing in Ioannina and its wider area, for which the region was famous in Ottoman times. Other surviving or excavated structures are

2755-430: Is to the period of Ali Pasha's rule that the present form of the castle largely dates; the modifications or repairs undertaken on the Byzantine walls by previous Ottoman governors are now no longer discernible, as Ali Pasha initiated a wide-ranging reconstruction of the walls in the early 19th century, which was completed in 1815. It incorporated, as far as was possible, the pre-existing Byzantine fortifications, while adding

2900-692: 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 ,

3045-524: 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

3190-681: 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

3335-655: 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

3480-471: 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 ,

3625-717: The Danube . In the north and west were the Balkans, the corridors between the mountain ranges of Pindos , the Dinaric Alps , the Rhodopes and the Balkans . 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

3770-486: The Dukes of Athens . In 1267 Corcyra and much of Epirus were taken by Charles of Anjou , and in 1267/68 Michael II died. Michael VIII did not attempt to annex Epirus directly, and allowed Nikephoros I to succeed his father and deal with Charles, who captured Dyrrhachium in 1271. In 1279 Nikephoros allied with Charles against Michael VIII, agreeing to become Charles' vassal. With Charles' defeat soon after Nikephoros lost Albania to

3915-527: The Eastern Orthodox Church . Henry of Flanders demanded that Michael submit to the Latin Empire , which he did, at least nominally, by allowing his daughter to marry Henry's brother Eustace in 1209. Michael did not honour this alliance, assuming that mountainous Epirus would be mostly impenetrable by any Latins with whom he made and broke alliances. Meanwhile, Boniface's relatives from Montferrat made claims to Epirus as well, and in 1210 Michael allied with

4060-686: The Empire of Thessalonica in 1224, and Thrace as far east as Didymoteicho and Adrianople , and was on the verge of recapturing Constantinople and restoring the Byzantine Empire before the Battle of Klokotnitsa in 1230 where he was defeated by the Bulgarian Empire . After that, the Epirote state contracted to its core in Epirus and Thessaly, and was forced into vassalage to other regional powers. It nevertheless managed to retain its autonomy until being conquered by

4205-569: 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

4350-582: 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 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

4495-611: 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 ,

4640-689: The Ottoman Turks against the Albanians. In 1399 the Albanian leader of Principality of Gjirokastër , Gjon Zenebishi captured the Despot Esau de' Buondelmonti and released him after 15 months, when his relatives in Italy offered a huge amount of money as a ransom. By 1416 the Tocco family of Cephalonia succeeded in reuniting Epirus, or at least in asserting their control over its towns. But internal dissension eased

4785-565: The Pechenegs , who were caught by surprise and annihilated at the Battle of Levounion on 28 April 1091. 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

4930-454: 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,

In the Byzantine world, the term Dysis ( Δύσις ), meaning "West", which historically referred to Dalmatia , Macedonia and Sicily , or even

5220-599: 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, 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

5365-516: The Soufari Sarai ("horsemen's palace"), a cavalry barracks built in the last years of Ali Pasha's rule (1815–20). There is also a Byzantine bath complex in the vicinity. The southeastern citadel, better known by its Ottoman name "Its Kale" (a Greek rendition of the proper Turkish iç Kale meaning "citadel"), forms essentially a separate fortress within the old town, covering an area of ca. 30,000 m. Traditionally its establishment has been ascribed to

5510-633: The Taxiarches and the church of the Pantokrator . Under Ali Pasha, the Its Kale was completely rebuilt and became the main residence of the powerful ruler. It was here that he built his palace ( saray ), beginning in 1788. The palace is described by European travellers and depicted in a print by W. L. Leitch and engraved by H. Adlard, as a large and complex two-storey structure with many windows giving excellent view to Lake Pamvotis. The palace continued to serve as

5655-441: The Tocco family , rulers of Cephalonia and Zakynthos , from 1411 until the capture of the city by the Ottoman Empire on 9 October 1430. In the years immediately after 1204, the city walls and the northeastern citadel were reconstructed, while further reconstruction was undertaken in 1367–84 under Thomas Preljubović . The course of the Byzantine walls largely coincides with the extant fortification, but few details about it, such as

5800-526: The Venetians and attacked Boniface's Kingdom of Thessalonica . Pope Innocent III excommunicated him in response. Henry forced Michael into a renewed nominal alliance later that year. Michael turned his attention to capturing other strategically important Latin-held towns, including Larissa and Dyrrhachium . He also took control of the ports on the Gulf of Corinth . In 1214 he captured Corcyra from Venice , but he

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

6090-453: 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 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

6235-587: The "Despotate of Epirus" and its rulers are summarily attributed the title of " Despot " from its inception, but this use is not strictly accurate. First of all, the title of "Despot" was not borne by all Epirote rulers: the state's founder, Michael I Komnenos Doukas , never used it, and is only anachronistically referred to as " Despot of Epirus " in 14th-century Western European sources. His successor Theodore Komnenos Doukas did not use it either, and actually crowned himself emperor ( basileus ) at Thessalonica c.  1225 . The first ruler of Epirus to receive

6380-514: The "land of the Romans" ( Bilād al-Rūm ), but the people of medieval Western Europe preferred to call them "Greeks" ( Graeci ), due to having 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,

6525-655: 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 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

6670-415: The 15th-century historian Laonikos Chalkokondyles , whose works were widely propagated, including by Hieronymus Wolf . "Byzantine" 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

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

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

The citadel became the Muslim religious centre of the city. Today the Aslan Pasha Mosque houses the Municipal Ethnographic Museum of Ioannina . Outside the citadel but in close proximity lie the Turkish Library, probably attached to the madrasah, an Ottoman bath ( hamam ) and

The Florentine adventurer Esau de' Buondelmonti captured the city from its Serbian rulers in 1385, to be followed by

7395-408: 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

7540-600: The Byzantines. Under Andronikos II Palaiologos , son of Michael VIII, Nikephoros renewed the alliance with Constantinople. Nikephoros, however, was persuaded to ally with Charles II of Naples in 1292, although Charles was defeated by Andronikos's fleet. Nikephoros married his daughter to Charles's son Philip I of Taranto and sold much of his territory to him. After Nikephoros's death in c. 1297 Byzantine influence grew under his widow Anna, Andronikos's cousin, who ruled as regent for her young son Thomas I Komnenos Doukas . In 1306 she revolted against Philip in favour of Andronikos;

7685-424: The Despotate. Anna tried to negotiate and obtain the Despotate for her son when he came of age, but Andronikos demanded the complete surrender of the Despotate to which she finally agreed. Thus Epirus came peacefully under imperial rule, with Theodore Synadenos as governor. The imperials had insisted that Nikephoros would be engaged to one of the daughters of the emperor's right-hand man, John Kantakouzenos . When

7830-415: 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

7975-432: 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

8120-455: The Epirote rulers as "Despots of Epirus" is technically incorrect. The title of Despot did not imply any specific territorial jurisdiction, nor was it hereditary; it was merely the highest rank in the Byzantine court hierarchy , awarded by a reigning emperor to close relatives, usually his sons. Consequently, it was often borne by the princes sent to govern semi-autonomous appanages and only later came to be associated with these territories as

8265-500: The Latin inhabitants were expelled but she was forced to return some territory to Philip. In 1312 Philip abandoned his claim to Epirus and claimed the defunct Latin Empire of Constantinople instead as the inheritance of his wife Catherine II of Valois, Princess of Achaea . Anna succeeded in marrying off Thomas to a daughter of Michael IX, but Thomas was assassinated in 1318 by his cousin Nicholas Orsini , who married his widow and claimed to rule not only Epirus, but all of Greece; his rule

8410-630: The Latins out of Thrace . In 1227 Theodore crowned himself Byzantine emperor, although this was not recognized by most Greeks, especially not the Patriarch in Nicaea. In 1230 Theodore broke the truce with Bulgaria , hoping to remove Ivan Asen II , who had held him back from attacking Constantinople. In the battle of Klokotnitsa (near Haskovo in Bulgaria) the Bulgarian emperor defeated Theodore, capturing and later blinding him. His brother Manuel Komnenos Doukas took power in Thessalonica, but Epirus itself soon broke away under Michael I's illegitimate son, Michael II Komnenos Doukas . Manuel awarded Michael

8555-411: 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

8700-405: 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

By the end of the year the imperial army returned to the area, and in the following year, 1340, Andronikos III himself arrived together with John Kantakouzenos. Nikephoros was persuaded through diplomacy to recognize the authority of the emperor. He surrendered Thomokastron, married Maria Kantakouzene, the daughter of John Kantakouzenos, and received

8990-401: 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

9135-413: 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

The term "Despotate of Epirus" is thus sometimes replaced by "(Independent) State of Epirus" in more recent historiography. The Epirote realm itself did not have an official name. Contemporaries, particularly in Western Europe, used the term Romania (Greek: Ῥωμανία , romanized:  Rhōmania , lit.   'land of

9570-426: 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

9715-486: 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

9860-401: 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

10005-429: 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

10150-522: 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

10295-401: 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 )

10440-568: 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

10585-728: The battle of Klokotnitsa. Theodore's younger son Demetrios Angelos Doukas lost Thessalonica to Nicaea in 1246 and Michael II of Epirus allied with the Latins against the Nicaeans. In 1248 John III Doukas Vatatzes of Nicaea forced Michael to recognize him as emperor, and officially recognized him in turn as despotēs in Epirus. Vatatzes' granddaughter Maria later (in 1256) married Michael's son Nikephoros , although she died in 1258. Also in 1248 Michael's daughter Anna married William II , Prince of Achaea , and Michael decided to honour this alliance over his obligations to Vatatzes. The allies were defeated in

10730-488: 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 ,

10875-490: The citadel, lies the Fethiye Mosque with the tomb of Ali Pasha and one of his wives to the northwest, covered by an iron lattice work. The mosque occupies the space of the city's Byzantine-era cathedral, and was originally built after the Ottoman conquest in 1430. Rebuilt in grander style in the 17th century, its present form dates to its reconstruction by Ali Pasha c.  1795 . The main surviving part of Ali's palace

11020-413: 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

11165-462: The city's administrative centre until 1870 when it was torn down, although it had already been badly damaged during the 1821–22 siege by the Sultan's troops that brought about Ali's downfall. Excavations have shown that the selamlik was most likely located on the northern side, with the harem and the women's quarters on the southern. The surviving ruins belong mostly to the southern portion, including

11310-503: The clan of Muriq Shpata held Aetoloacarnania, with Angelokastron as its capital. In 1367 a part of the Epirotan Despotate was resurrected under local Serbian nobleman Thomas II Preljubović , who kept Ioannina. After Thomas' death in 1384, his widow remarried in 1385 and transferred the Despotate to homage of Italian nobility. The state tradition was carried on by the Serbian and Italian rulers of Ioannina , who solicited aid from

11455-589: 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

11600-499: 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

11745-471: 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

11890-433: 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

12035-527: 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

12180-418: 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 a distinction between the earlier Roman Empire and the later Byzantine Empire . During the earlier Pax Romana period,

12325-523: 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

12470-495: 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

12615-460: 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

12760-514: 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

12905-606: 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

13050-403: The ensuing conflict at the Battle of Pelagonia in 1259. Emperor Theodore II Laskaris allied with Michael II, and their children, betrothed by John years before, finally married in 1256, with Theodore receiving Dyrrhachium in return. Michael did not accept this transfer of land, and in 1257 he revolted, defeating a Nicaean army led by George Acropolites . As Michael marched on Thessalonica, he

13195-434: The entire European part of the Empire, also came into use already in the 13th century when juxtaposing Epirus to its eastern rival, the Empire of Nicaea , which was then called Anatolē ( Ἀνατολή ), "East". Moreover, the term " Hellenes " was widely used instead of the earlier "Romans" by the 13th-century court of the Despotate to describe its population. The Epirote state was founded in 1205 by Michael Komnenos Doukas ,

13340-569: 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,

13485-544: 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

13630-451: The growing power of Nicaea and could not stop Theodore from capturing Thessalonica in 1224. Theodore now challenged Nicaea for the imperial title and crowned himself emperor, founding the short-lived Empire of Thessalonica . In 1225, after John III Doukas Vatatzes of Nicaea had taken Adrianople , Theodore arrived and took it back from him. Theodore also allied with the Bulgarians and drove

13775-483: 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

13920-583: The historiographical periodizations of " Roman history ", " late antiquity ", and "Byzantine history" significantly overlap, there 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

14065-471: The inhabitants of ancient Euroia . This view is not supported, however, by any concrete archaeological evidence. Early 21st-century excavations furthermore have brought to light fortifications dating to the Hellenistic period (4th–3rd centuries BC), the course of which was largely followed by later reconstructions of the fortress in the Byzantine and Ottoman periods. The identification of the site with one of

14210-475: The kitchens, dating to the early 19th century, located in the northwestern part of the citadel, which now serve as a refectory; the gunpowder store to the northeast of the Fethiye Mosque, which today serves as an educational space, with a ruined building of unknown purpose between it and the kitchens, as well as the ruined base of another large Byzantine-era circular tower; a large two-storey building northeast of

14355-404: The known ancient cities of Epirus has not yet been possible. The Greek archaeologist K. Tsoures dated the Byzantine city walls and the northeastern citadel to the 10th century. Additions in the late 11th century, including the southeastern citadel, are traditionally ascribed to the short-lived occupation of the city by the Normans under the leadership of Bohemond of Taranto . After the fall of

14500-708: 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

14645-415: The legitimate successor of the Byzantine Empire during the subsequent struggle for Constantinople , along with the Empire of Nicaea and the Empire of Trebizond ; its rulers briefly proclaiming themselves as Emperors in 1227–1242 (during which it is most often called the Empire of Thessalonica ). The term "Despotate of Epirus" is, like "Byzantine Empire" itself, a modern historiographic convention and not

14790-418: 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

14935-579: 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,

15080-542: 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

15225-567: 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

15370-568: The new home of many refugees from Constantinople , Thessaly , and the Peloponnese , and Michael was described as a second Noah , rescuing men from the Latin flood. John X Kamateros , the Patriarch of Constantinople , did not consider him a legitimate successor and instead joined Theodore I Laskaris in Nicaea ; Michael instead recognized the authority of Pope Innocent III over Epirus, cutting ties to

15515-466: 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

15660-496: The northeastern citadel, now dominated by the Ottoman Aslan Pasha Mosque , and the much larger southeastern citadel, also known as Its Kale (from Turkish : Iç Kale , "Inner Castle"). The northeastern citadel covers an area of approximately 6,000 m, and is surrounded by a wall that dates partly to the Byzantine period, including the monumental southern gate, flanked by a large circular tower. In Byzantine times, this

15805-569: The number and structure of the towers, were known until excavations during the last couple of decades. The city remained under Ottoman rule from 1430 until captured by Greece in the First Balkan War in 1913. In the Ottoman era, the city enjoyed considerable prosperity, and reached the height of its pre-eminence under the rule of Ali Pasha, who became the ruler of a large semi-autonomous state encompassing much of modern-day Greece and Albania between 1787 and his downfall and execution in 1822. It

15950-470: The occupation of the city by Bohemond in 1082, and the main Byzantine relic of the period, the large circular tower in the centre of the citadel, is known as the Tower of Bohemond. Here too, however, recent excavations have brought to light Hellenistic-era foundations. Literary sources record that in the Byzantine period, the citadel housed the residences of the city's archontes , as well as the cathedral church of

16095-555: 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

16240-521: 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

16385-410: 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

16530-590: 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

16675-501: The practice became regularized (aside from Epirus, the Despotate of the Morea is the most notable case). The territorial term "despotate" itself (in Greek δεσποτᾶτον , despotaton ) was first used in contemporary sources for Epirus only from the 14th century on, e.g. in the Chronicle of the Morea , in the history of John Kantakouzenos , the hagiography of St. Niphon, or the Chronicle of

16820-458: The restored Palaiologan Byzantine Empire in ca. 1337. In the 1410s, the Count palatine of Cephalonia and Zakynthos Carlo I Tocco managed to reunite the core of the Epirote state, but his successors gradually lost it to the advancing Ottoman Empire , with the last stronghold, Vonitsa , falling to the Ottomans in 1479. In traditional and modern historiography , the Epirote state is usually termed

16965-483: The ruins of the circular Tower of Bohemond. After the Greek capture of the city in 1913, the site of the main palace complex was later used for the construction of the city's military hospital, which in turn gave way in 1958 to new building, designed by V. Harisis, intended to serve as a royal pavilion. Since 1995 this houses the Byzantine Museum of Ioannina . Next to the museum, on the easternmost and highest part of

17110-533: The rule of an emperor. The senate had its own identity but would become an extension of the emperor's court, becoming largely ceremonial. Despotate of Epirus The Despotate of Epirus ( Medieval Greek : Δεσποτᾶτον τῆς Ἠπείρου ) was one of the Greek successor states of the Byzantine Empire established in the aftermath of the Fourth Crusade in 1204 by a branch of the Angelos dynasty. It claimed to be

17255-543: 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,

17400-478: The time of the engagement came, Nikephoros had vanished. Andronikos learned that Nikephoros had fled to Italy, with the help of members of the Epirote aristocracy who supported an independent Epirus. He stayed in Taranto , Italy, in the court of Catherine II of Valois (Philip of Taranto's widow), the titular empress of Constantinople. In 1339 a revolt began, supported by Catherine of Valois, who had previously moved to

17545-532: The title of panhypersebastos . The Empire soon fell into a civil war between John V Palaiologos and John VI Kantakouzenos, and Epirus was conquered by the Serbian tsar Stefan Dušan in 1348, who appointed his brother, despot Simeon Nemanjić-Palailogos as governor of the province. Nikephoros II took advantage of the Byzantine civil war and the death of Dušan (1355) to escape and to reestablish himself in Epirus in 1356, to which he also added Thessaly. Nikephoros

17690-443: The title of Despot —making Michael the first Epirote ruler to bear the title—as a sign of his nominal dependency on Thessalonica, but Michael was de facto independent, which he demonstrated by seizing Corfu in ca. 1236. In the rump Empire of Thessalonica, after Theodore was released in 1237, he overthrew his brother Manuel, and set up his son John Komnenos Doukas as ruler of Thessalonica. Thessalonica never regained its power after

17835-550: The title of Despot was Michael II , from his uncle Manuel of Thessalonica in the 1230s, and then again, as a sign of submission and vassalage, from the Nicaean emperor John III Vatatzes . Earlier historians assumed that Michael I was indeed named "Despot" by the deposed emperor Alexios III Angelos after ransoming him from Latin captivity in c.  1206/7 or c.  1210 ; this has been disproven by more recent research. Furthermore, even after Michael II, speaking of

17980-442: 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

18125-458: 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

18270-483: 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 the capital to Constantinople and legalised Christianity . Under Theodosius I ( r. 379–395 ), Christianity became

18415-422: 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

18560-403: Was assassinated later that year and was succeeded by his half-brother Theodore. Theodore Komnenos Doukas immediately set out to attack Thessalonica , and he fought with the Bulgarians along the way. Henry of Flanders died on the way to counterattack, and in 1217 Theodore captured his successor Peter of Courtenay , most likely executing him. The Latin Empire, however, became distracted by

18705-505: Was attacked by King Manfred of Sicily , who conquered Albania and Corcyra . However, Michael immediately allied with him by marrying his daughter Helena to him. After Theodore II died, Michael, Manuel , and William II fought the new Nicaean emperor, Michael VIII Palaiologos . The alliance was very unstable and in 1259 William was captured at the disastrous Battle of Pelagonia . Michael VIII went on to capture Michael II's capital of Arta , leaving Epirus with only Ioannina and Vonitsa. Arta

18850-592: 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

18995-515: Was called the "Upper Tower" ( επάνω γουλάς ) and was the seat of the local governor and later of the Despots of Epirus . The citadel comprised a palace as well as a church dedicated to Saint John. Following the failed uprising of Dionysius the Philosopher in 1611 and the subsequent expulsion of the Christian population from the walled town, the church of St. John was torn down and replaced in 1618 by

19140-560: 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

19285-550: 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;

19430-573: 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

19575-540: 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

19720-489: Was killed in battle putting down an Albanian revolt in 1359, and the territory of the former despotate became a component part of the personal Empire of Dušan's brother Simeon Nemanjić-Palailogos . Simeon was also governing Thessaly at the time, and, as the Chronicle of Ioannina shows, he left much of the territory under the control of Albanian clans establishing short-lived entities: the clan of Pjetër Losha held Arta , and

19865-670: Was limited only to Akamania, or the southern part of Epirus. He was overthrown by his brother John in 1323, who attempted to balance submission to Constantinople with cooperation with the Angevins of Naples, who also claimed Greece as part of their domains. John was poisoned around 1335 by his wife Anna, who became regent for their son Nikephoros II . In 1337 the new Emperor, Andronikos III Palaiologos , arrived in northern Epirus with an army partly composed of 2,000 Turks contributed by his ally Umur of Aydın . Andronikos first dealt with unrest due to attacks by Albanians and then turned his interest to

20010-556: 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

20155-406: 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

20300-506: 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

20445-499: Was only used to describe the inhabitants of that city; it did not refer to the empire, which they called Romanía —"Romanland". After 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

20590-490: 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

20735-452: Was recovered by 1260 while Michael VIII was occupied against Constantinople. After Michael VIII restored the empire in Constantinople in 1261 he frequently harassed Epirus, and forced Michael's son Nikephoros to marry his niece Anna Palaiologina Kantakouzene in 1265.
