The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire centered 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 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 the predominance of Greek instead of Latin, modern historians continue to make a distinction between the earlier Roman Empire and the later Byzantine Empire.
Following the Norman conquest of Byzantine Italy and Saracen Sicily, the Byzantine emperor, Michael VII Doukas (r. 1071–1078), betrothed his son to Robert Guiscard's daughter. When Michael was deposed, Robert took this as an excuse to invade the Byzantine Empire in 1081. His army laid siege to Dyrrhachium, but his fleet was defeated by the Venetians. On October 18, the Normans engaged a Byzantine army under Alexios I Komnenos outside Dyrrhachium. The battle began with the Byzantine right wing routing the Norman left wing, which broke and fled. Varangian mercenaries joined in the pursuit of the fleeing Normans, but became separated from the main force and were massacred. Norman knights in the centre attacked the Byzantine centre and routed it, causing the bulk of the Byzantine army to rout. (Full article...)
From the start, the regime faced numerous problems. The Turks of Asia Minor had begun conducting raids and expanding into Byzantine territory in Asia Minor by 1263, just two years after the enthronement of the first Palaiologos emperor Michael VIII. Anatolia, which had formed the very heart of the shrinking empire, was systematically lost to numerous Turkic ghazis, whose raids evolved into conquering expeditions inspired by Islamic zeal, the prospect of economic gain, and the desire to seek refuge from the Mongols after the disastrous Battle of Köse Dağ in 1243. The Palaiologoi were engaged on several fronts, often continually, while the empire's supply of food and manpower dwindled. In this period, the Byzantine Empire found itself continually at war, both civil and interstate, with most interstate conflicts being with other Christian empires. Most commonly, these comprised the Second Bulgarian Empire, the Serbian Empire, the remnants of the Latin Empire and even the Knights Hospitaller. (Full article...)

The second Arab siege of Constantinople was a combined land and sea offensive in 717–718 by the Muslim Arabs of the Umayyad Caliphate against the capital city of the Byzantine Empire, Constantinople. The campaign marked the culmination of twenty years of attacks and progressive Arab occupation of the Byzantine borderlands, while Byzantine strength was sapped by prolonged internal turmoil. In 716, after years of preparations, the Arabs, led by Maslama ibn Abd al-Malik, invaded Byzantine Asia Minor. The Arabs initially hoped to exploit Byzantine civil strife and made common cause with the general Leo III the Isaurian, who had risen up against Emperor Theodosius III. Leo, however, tricked them and secured the Byzantine throne for himself.
After wintering in the western coastlands of Asia Minor, the Arab army crossed into Thrace in early summer 717 and built siege lines to blockade the city, which was protected by the massive Theodosian Walls. The Arab fleet, which accompanied the land army and was meant to complete the city's blockade by sea, was neutralized soon after its arrival by the Byzantine navy through the use of Greek fire. This allowed Constantinople to be resupplied by sea, while the Arab army was crippled by famine and disease during the unusually hard winter that followed. In spring 718, two Arab fleets sent as reinforcements were destroyed by the Byzantines after their Christian crews defected, and an additional army sent overland through Asia Minor was ambushed and defeated. Coupled with attacks by the Bulgars on their rear, the Arabs were forced to lift the siege on 15 August 718. On its return journey, the Arab fleet was almost completely destroyed by natural disasters. (Full article...)

The Empire of Nicaea (Greek: Βασιλεία Ῥωμαίων) or the Nicene Empire was the largest of the three Byzantine Greekrump states founded by the aristocracy of the Byzantine Empire that fled when Constantinople was occupied by Western European and Venetian armed forces during the Fourth Crusade, a military event known as the Sack of Constantinople. Like the other Byzantine rump states that formed due to the 1204 fracturing of the empire, such as the Empire of Trebizond and the Despotate of Epirus, it was a continuation of the eastern half of the Roman Empire that survived well into the medieval period. A fourth state, known in historiography as the Latin Empire, was established by an army of Crusaders and the Republic of Venice after the capture of Constantinople and the surrounding environs.
Founded by the Laskaris family, it lasted from 1204 to 1261, when the Nicenes restored the Byzantine Empire in Constantinople after its recapture. Thus, the Nicene Empire is seen to be a direct continuation of the Byzantine Empire, as it had fully assumed the traditional titles and government of the Byzantines in 1205. (Full article...)
The first action that would lead to a formal schism was taken in 1053: the Greek churches in southern Italy were required to conform to Latin practices, under threat of closure. In retaliation, Patriarch Michael I Cerularius of Constantinople ordered the closure of all Latin churches in Constantinople. In 1054, the papal legate sent by Leo IX travelled to Constantinople in order, among other things, to deny Cerularius the title of "ecumenical patriarch" and insist that he recognize the pope's claim to be the head of all of the churches. The main purposes of the papal legation were to seek help from the Byzantine emperor, Constantine IX Monomachos, in view of the Norman conquest of southern Italy, and to respond to Leo of Ohrid's attacks on the use of unleavened bread and other Western customs, attacks that had the support of Cerularius. The historian Axel Bayer says that the legation was sent in response to two letters, one from the emperor seeking help to organize a joint military campaign by the eastern and western empires against the Normans, and the other from Cerularius. When the leader of the legation, Cardinal Humbert of Silva Candida, O.S.B., learned that Cerularius had refused to accept the demand, he excommunicated him, and in response Cerularius excommunicated Humbert and the other legates. According to Ware, "Even after 1054 friendly relations between East and West continued. The two parts of Christendom were not yet conscious of a great gulf of separation between them. ... The dispute remained something of which ordinary Christians in East and West were largely unaware". (Full article...)

The Byzantine Iconoclasm (Ancient Greek: Εἰκονομαχία, romanized: Eikonomachía, lit. 'image struggle', 'war on icons') were two periods in the history of the Byzantine Empire when the use of religious images or icons was opposed by religious and imperial authorities within the Ecumenical Patriarchate (at the time still comprising the Roman-Latin and the Eastern-Orthodox traditions) and the temporal imperial hierarchy. The First Iconoclasm, as it is sometimes called, occurred between about 726 and 787, while the Second Iconoclasm occurred between 814 and 842. According to the traditional view, Byzantine Iconoclasm was started by a ban on religious images promulgated by the Byzantine Emperor Leo III the Isaurian, and continued under his successors. It was accompanied by widespread destruction of religious images and persecution of supporters of the veneration of images. The Papacy remained firmly in support of the use of religious images throughout the period, and the whole episode widened the growing divergence between the Byzantine and Carolingian traditions in what was still a unified European Church, as well as facilitating the reduction or removal of Byzantine political control over parts of the Italian Peninsula.
Iconoclasm is the deliberate destruction within a culture of the culture's own religious images and other symbols or monuments, usually for religious or political motives. People who engage in or support iconoclasm are called iconoclasts, Greek for 'breakers of icons' (εἰκονοκλάσται), a term that has come to be applied figuratively to any person who breaks or disdains established dogmata or conventions. Conversely, people who revere or venerate religious images are derisively called "iconolaters" (εἰκονολάτρες). They are normally known as "iconodules" (εἰκονόδουλοι), or "iconophiles" (εἰκονόφιλοι). These terms were, however, not a part of the Byzantine debate over images. They have been brought into common usage by modern historians (from the seventeenth century) and their application to Byzantium increased considerably in the late twentieth century. The Byzantine term for the debate over religious imagery, iconomachy, means 'struggle over images' or 'image struggle'. Some sources also say that the Iconoclasts were against intercession to the saints and denied the usage of relics; however, it is disputed. (Full article...)
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 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 the restored PalaiologanByzantine Empire in ca. 1337. In the 1410s, the Count palatine of Cephalonia and ZakynthosCarlo 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.

Greek fire was an incendiarychemical weapon manufactured in and used by the Eastern Roman Empire from the seventh through the fourteenth centuries. The recipe for Greek fire was a closely-guarded state secret, but historians speculate it may have been made by combining pine resin, naphtha, quicklime, calcium phosphide, sulfur, or niter. Roman sailors would toss grenades loaded with Greek fire onto enemy ships or spray it from tubes. Its ability to burn on water made it an effective and destructive naval incendiary weapon, and rival powers tried unsuccessfully to copy the material. (Full article...)
The richest interiors were finished with thin plates of marble or coloured and patterned stone. Some of the columns were also made of marble. Other widely used materials were bricks and stone. Mosaics made of stone or glass tesserae were also elements of interior architecture. Precious wood furniture, like beds, chairs, stools, tables, bookshelves and silver or golden cups with beautiful reliefs, decorated Byzantine interiors. (Full article...)
A group of Andalusian exiles led by Abu Hafs Umar al-Iqritishi conquered Crete in either 824 or 827/828, and established an independent Islamic state. The Byzantines launched a campaign that took most of the island back in 842-43 under Theoktistos, but the reconquest was not completed and would soon be reversed. Later attempts by the Byzantine Empire to recover the island failed, and for the approximately 135 years of its existence, the emirate was one of the major foes of Byzantium. Crete commanded the sea lanes of the Eastern Mediterranean and functioned as a forward base and haven for Muslim corsair fleets that ravaged the Byzantine-controlled shores of the Aegean Sea. The emirate's internal history is less well known, but all accounts point to considerable prosperity deriving not only from piracy but also from extensive trade and agriculture. The emirate was brought to an end by Nikephoros Phokas, who successfully campaigned against it in 960–961, re-annexing the island to the Byzantine Empire. (Full article...)

The Byzantine economy was among the most robust economies in the Mediterranean for many centuries. Constantinople was a prime hub in a trading network that at various times extended across nearly all of Eurasia and North Africa. Some scholars argue that, up until the arrival of the Arabs in the 7th century, the Eastern Roman Empire had the most powerful economy in the world. The Arab conquests, however, would represent a substantial reversal of fortunes contributing to a period of decline and stagnation. Constantine V's reforms (c. 765) marked the beginning of a revival that continued until 1204. From the 10th century until the end of the 12th, the Byzantine Empire projected an image of luxury, and the travelers were impressed by the wealth accumulated in the capital. All this changed with the arrival of the Fourth Crusade, which was an economic catastrophe. The Palaiologoi tried to revive the economy, but the late Byzantine state would not gain full control of either the foreign or domestic economic forces.
One of the economic foundations of the empire was trade. The state strictly controlled both the internal and the international trade, and retained the monopoly of issuing coinage. Constantinople remained the single most important commercial centre of Europe for much of the Medieval era, which it held until the Republic of Venice slowly began to overtake Byzantine merchants in trade; first through tax exemption under the Komnenoi, then under the Latin Empire.

Byzantine medicine encompasses the common medical practices of the Byzantine Empire from c. 400 AD to 1453 AD. Byzantine medicine was notable for building upon the knowledge base developed by its Greco-Roman predecessors. In preserving medical practices from antiquity, Byzantine medicine influenced Islamic medicine and fostered the Western rebirth of medicine during the Renaissance.
Byzantine physicians often compiled and standardized medical knowledge into textbooks. Their records tended to include both diagnostic explanations and technical drawings. The Medical Compendium in Seven Books, written by the leading physician Paul of Aegina, survived as a particularly thorough source of medical knowledge. This compendium, written in the late seventh century, remained in use as a standard textbook for the following 800 years. This tradition of compilation continued from around the tenth century into the twentieth through the genre of medical writings known as iatrosophia. (Full article...)

Byzantine art comprises the body of artistic products of the Eastern Roman Empire, as well as the nations and states that inherited culturally from the empire. Though the empire itself emerged from the decline of western Rome and lasted until the Fall of Constantinople in 1453, the start date of the Byzantine period is rather clearer in art history than in political history, if still imprecise. Many Eastern Orthodox states in Eastern Europe, as well as to some degree the Islamic states of the eastern Mediterranean, preserved many aspects of the empire's culture and art for centuries afterward.
A number of contemporary states with the Eastern Roman (Byzantine) Empire were culturally influenced by it without actually being part of it (the "Byzantine commonwealth"). These included Kievan Rus', as well as some non-Orthodox states like the Republic of Venice, which separated from the Byzantine Empire in the 10th century, and the Kingdom of Sicily, which had close ties to the Byzantine Empire and had also been a Byzantine territory until the 10th century with a large Greek-speaking population persisting into the 12th century. Other states having a Byzantine artistic tradition, had oscillated throughout the Middle Ages between being part of the Byzantine Empire and having periods of independence, such as Serbia and Bulgaria. After the fall of the Byzantine capital of Constantinople in 1453, art produced by Eastern Orthodox Christians living in the Ottoman Empire was often called "post-Byzantine." Certain artistic traditions that originated in the Byzantine Empire, particularly in regard to icon painting and church architecture, are maintained in Greece, Cyprus, Serbia, Bulgaria, Romania, Russia and other Eastern Orthodox countries to the present day.

Byzantine currency, money used in the Eastern Roman Empire after the fall of the West, consisted of mainly two types of coins: goldsolidi and hyperpyra and a variety of clearly valued bronze coins. By the 15th century, the currency was issued only in debased silver stavrata and minor copper coins with no gold issue.
The Byzantine Empire established and operated several mints throughout its history. Aside from the main metropolitan mint in the capital, Constantinople, a varying number of provincial mints were also established in other urban centres, especially during the 6th century. Most provincial mints except for Syracuse were closed or lost to invasions by the mid-7th century. After the loss of Syracuse in 878, Constantinople became the sole mint for gold and silver coinage until the late 11th century, when major provincial mints began to re-appear. Many mints, both imperial and, as the Byzantine world fragmented, belonging to autonomous local rulers, were operated in the 12th to 14th centuries. Constantinople and Trebizond, the seat of the independent Empire of Trebizond (1204–1461), survived until their conquest by the Ottoman Turks in the mid-15th century. (Full article...)

The Fourth Crusade (1202–1204) was a Latin Christian armed expedition called by Pope Innocent III. The stated intent of the expedition was to recapture the Muslim-controlled city of Jerusalem, by first defeating the powerful Egyptian Ayyubid Sultanate. However, a sequence of economic and political events culminated in the Crusader army's 1202 siege of Zara and the 1204 sack of Constantinople, rather than the conquest of Egypt as originally planned. This led to the Partitio terrarum imperii Romaniae or the partition of the Byzantine Empire by the Crusaders and their Venetian allies leading to a period known as Frankokratia, or "Rule of the Franks" in Greek.
The Republic of Venice contracted with the Crusader leaders to build a dedicated fleet to transport their invasion force. However, the leaders greatly overestimated the number of soldiers who would embark from Venice, since many sailed from other ports, and the army that appeared could not pay the contracted price. In lieu of payment, the Venetian Doge Enrico Dandolo proposed that the Crusaders back him in attacking the rebellious city of Zadar (Zara) on the eastern Adriatic coast. This led in November 1202 to the siege and sack of Zara, the first attack against a Catholic city by a Catholic Crusader army, despite Pope Innocent III's calls for the Crusaders not to attack fellow Christians. The city was then brought under Venetian control. When the Pope heard of this, he temporarily excommunicated the Crusader army. (Full article...)
The work as planned had three parts: the Code (Codex) is a compilation, by selection and extraction, of imperial enactments to date; the Digest or Pandects (the Latin title contains both Digesta and Pandectae) is an encyclopedia composed of mostly brief extracts from the writings of Roman jurists; and the Institutes (Institutiones) is a student textbook, mainly introducing the Code, although it has important conceptual elements that are less developed in the Code or the Digest. All three parts, even the textbook, were given force of law. They were intended to be, together, the sole source of law; reference to any other source, including the original texts from which the Code and the Digest had been taken, was forbidden. Nonetheless, Justinian found himself having to enact further laws; today these are counted as a fourth part of the Corpus, the Novellae Constitutiones (Novels, literally New Laws). (Full article...)

The Arab–Byzantine wars were a series of wars between a number of MuslimArab dynasties and the Byzantine Empire from the 7th to the 11th century. Conflict started during the initial Muslim conquests, under the expansionist Rashidun and Umayyadcaliphs, in the 7th century and continued by their successors until the mid-11th century.
The emergence of Muslim Arabs from Arabia in the 630s resulted in the rapid loss of Byzantium's southern provinces (Syria and Egypt) to the Arab Caliphate. Over the next fifty years, under the Umayyad caliphs, the Arabs would launch repeated raids into still-Byzantine Asia Minor, twice besiege the Byzantine capital of Constantinople, and conquer the Byzantine Exarchate of Africa. The situation did not stabilize until after the failure of the Second Arab Siege of Constantinople in 718, when the Taurus Mountains on the eastern rim of Asia Minor became established as the mutual, heavily fortified and largely depopulated frontier. Under the Abbasid Empire, relations became more normal, with embassies exchanged and even periods of truce, but conflict remained the norm, with almost annual raids and counter-raids, sponsored either by the Abbasid government or by local rulers, well into the 10th century.

Taking advantage of the situation, the SeljukSultanate of Rum began seizing territory in western Anatolia, until the Nicaean Empire was able to repulse the Seljuk Turks from the remaining territories still under Byzantine rule. Eventually Constantinople was re-taken from the Latin Empire in 1261 by the Nicaean Empire. The position of the Byzantine Empire in Europe remained uncertain due to the presence of the rivals in Epirus, Serbia and Bulgaria. This, combined with the declining power of the Sultanate of Rum (Byzantium's chief rival in Asia Minor) led to the removal of troops from Anatolia to maintain Byzantium's grip on Thrace.

Byzantine law was essentially a continuation of Roman law with increased Orthodox Christian and Hellenistic influence. Most sources define Byzantine law as the Roman legal traditions starting after the reign of Justinian I in the 6th century and ending with the Fall of Constantinople in the 15th century. Although future Byzantine codes and constitutions derived largely from Justinian's Corpus Juris Civilis, their main objectives were idealistic and ceremonial rather than practical. Following Hellenistic and Near-Eastern political systems, legislations were tools to idealize and display the sacred role and responsibility of the emperor as the holy monarch chosen by God and the incarnation of law "nómos émpsychos", thus having philosophical and religious purposes that idealized perfect Byzantine kingship.
Though during and after the European Renaissance Western legal practices were heavily influenced by Justinian's Code (the Corpus Juris Civilis) and Roman law during classical times, Byzantine law nevertheless had substantial influence on Western traditions during the Middle Ages and after.

The Byzantine Empire was ruled by emperors of the Komnenos dynasty for a period of 104 years, from 1081 to about 1185. The Komnenian (also spelled Comnenian) period comprises the reigns of five emperors, Alexios I, John II, Manuel I, Alexios II and Andronikos I. It was a period of sustained, though ultimately incomplete, restoration of the military, territorial, economic and political position of the Byzantine Empire.
Byzantium under the Komnenoi played a key role in the history of the Crusades in the Holy Land, while also exerting enormous cultural and political influence in Europe, the Near East, and the lands around the Mediterranean Sea. The Komnenian emperors, particularly John and Manuel, exerted great influence over the Crusader states of Outremer, whilst Alexios I played a key role in the course of the First Crusade, which he helped bring about.

As the chief aide and closest friend of Emperor Andronikos III, Kantakouzenos became regent for the underage John V upon Andronikos's death in June 1341. While Kantakouzenos was absent from Constantinople in September the same year, a coup d'état led by Alexios Apokaukos and the Patriarch John XIV secured the support of Empress Anna and established a new regency. In response, Kantakouzenos' army and supporters proclaimed him co-emperor in October, cementing the rift between himself and the new regency. The split immediately escalated into armed conflict.

The building is an example of Byzantine architecture. In the 16th century, during the Ottoman era, it was converted into a mosque; it became a museum in 1945, and was turned back into a mosque in 2020 by President Recep Tayyip Erdoğan. The interior of the building is covered with some of the finest surviving Byzantine Christian mosaics and frescoes, which were left in plain sight during Muslim worship throughout much of the Ottoman era. They were restored after the building was secularized and turned into a museum. (Full article...)
Thessalonica's ascendancy was brief, ending with the disastrous Battle of Klokotnitsa against Bulgaria in 1230, where Theodore Komnenos Doukas was captured. Reduced to a Bulgarian vassal, Theodore's brother and successor Manuel Komnenos Doukas was unable to prevent the loss of most of his brother's conquests in Macedonia and Thrace, while the original nucleus of the state, Epirus, broke free under Michael II Komnenos Doukas. Theodore recovered Thessalonica in 1237, installing his son John Komnenos Doukas, and after him Demetrios Angelos Doukas, as rulers of the city, while Manuel, with Nicaean support, seized Thessaly. The rulers of Thessalonica bore the imperial title from 1225/7 until 1242, when they were forced to renounce it and recognize the suzerainty of the rival Empire of Nicaea. The Komnenodoukai continued to rule as Despots of Thessalonica for four more years after that, but in 1246 the city was annexed by Nicaea. (Full article...)
Basil II Porphyrogenitus (Greek: Βασίλειος ΠορφυρογέννητοςBasileios Porphyrogennetos; 958 – 15 December 1025), nicknamed the Bulgar Slayer (Greek: ὁ Βουλγαροκτόνος, ho Boulgaroktónos), was the senior Byzantine emperor from 976 to 1025. He and his brother Constantine VIII were crowned before their father Romanos II died in 963, but they were too young to rule. The throne thus went to two generals, Nikephoros Phokas (r. 963–969) and John Tzimiskes (r. 969–976) before Basil became senior emperor, though his influential great-uncle Basil Lekapenos remained as the de facto ruler until 985. His reign of 49 years and 11 months was the longest of any Roman emperor.
Alexios I Megas Komnenos (Greek: Αλέξιος Κομνηνός; Georgian: ალექსი კომნენოსი; c. 1182 – 1 February 1222) or Alexius I Megas Comnenus was, with his brother David, the founder of the Empire of Trebizond and its ruler from 1204 until his death in 1222. The two brothers were the only male descendants of the Byzantine EmperorAndronikos I, who had been dethroned and killed in 1185, and thus claimed to represent the legitimate government of the Empire following the conquest of Constantinople by the Fourth Crusade in 1204. Although his rivals governing the Nicaean Empire succeeded in becoming the de facto successors, and rendered his dynastic claims to the imperial throne moot, Alexios' descendants continued to emphasize both their heritage and connection to the Komnenian dynasty by later referring to themselves as Megas Komnenos ("grand Komnenos").
While his brother David conquered a number of Byzantine provinces in northwestern Anatolia, Alexios defended his capital Trebizond from an unsuccessful siege by the Seljuk Turks around the year 1205. Further details of his reign are sparse. Muslim chroniclers record how, in 1214, Alexios was captured by the Turks in the field while defending Sinope; despite sending an envoy to seek their surrender the city refused to capitulate to Sultan Kaykaus I, and Alexios was tortured in sight of the Sinopians. The city submitted to Kaykaus and Alexios was freed after becoming Kaykaus' vassal. Alexios died at the age of forty. (Full article...)

Coin depicting John II Megas Komnenos
John II Megas Komnenos (Greek: Ἰωάννης Μέγας Κομνηνός, Iōannēs Megas Komnēnos) (c. 1262 – 16 August 1297) was a turkEmperor of Trebizond from June 1280 to his death in 1297. He was the youngest son of Emperor Manuel I and his third wife, Irene Syrikaina, a Trapezuntine noblewoman. John succeeded to the throne after his full-brother George was betrayed by his archons on the mountain of Taurezion. It was during his reign that the style of the rulers of Trebizond changed; until then, they claimed the traditional title of the Byzantine emperors, "Emperor and Autocrat of the Romans", but from John II on they changed it to "Emperor and Autocrat of all the East, the Iberians, and the Transmarine Provinces", although Iberia had been lost in the reign of Andronikos I Gidos.
John is the first ruler of Trebizond for whom we know more than a few incidents and hints; there is enough information to compose a connected narrative of the first part of his reign. The chronicle of Michael Panaretos, which is often terse and even cryptic, is relatively full for John's reign, and external sources add further details to Panaretos' account. Emperor John II faced many challenges to his rule, which partly explains his marriage to the daughter of the Byzantine emperor Michael VIII Palaiologos. (Full article...)
Theodore was the scion of a distinguished Byzantine aristocratic family related to the imperial Komnenos, Doukas, and Angelos dynasties. Nevertheless, nothing is known about Theodore's life before the conquest of Constantinople and dissolution of the Byzantine Empire by the Fourth Crusade in 1204. Following the fall of Constantinople, he served Theodore I Laskaris, founder of the Empire of Nicaea, for a few years before being called to Epirus, where his half-brother Michael I Komnenos Doukas had founded an independent principality. When Michael died in 1215, Theodore sidelined his brother's underage and illegitimate son Michael II and assumed the governance of the Epirote state. Theodore continued his brother's policy of territorial expansion. Allied with Serbia, he expanded into Macedonia, threatening the Latin Kingdom of Thessalonica. The capture of the Latin EmperorPeter II of Courtenay in 1217 opened the way to the gradual envelopment of Thessalonica, culminating in the city's fall in 1224. (Full article...)
Anastasius I Dicorus (Greek: Ἀναστάσιος, translit.Anastásios; c. 431 – 9 July 518) was Eastern Roman emperor from 491 to 518. A career civil servant, he came to the throne at the age of 61 after being chosen by the wife of his predecessor, Zeno. His reign was characterised by reforms and improvements in the empire's government, finances, economy and bureaucracy. He is noted for leaving the empire with a stable government, reinvigorated monetary economy and a sizeable budget surplus, which allowed the empire to pursue more ambitious policies under his successors, most notably Justinian I. Since many of Anastasius' reforms proved long-lasting, his influence over the empire endured for many centuries.
Anastasius was a Monophysite Christian and his personal religious tendencies caused tensions throughout his reign in the empire that was becoming increasingly divided along religious lines. He is venerated as a saint by the Syriac Orthodox Church on 29 July. (Full article...)

Alexios I Komnenos (Greek: Ἀλέξιος Κομνηνός, translit.Aléxios Komnēnós, 1057 – 15 August 1118), LatinizedAlexius I Comnenus, was Byzantine emperor from 1081 to 1118. Although he was not the first emperor of the Komnenian dynasty, it was during his reign that the Komnenos family came to full power and initiated a hereditary succession to the throne. Inheriting a collapsing empire and faced with constant warfare during his reign against both the Seljuq Turks in Asia Minor and the Normans in the western Balkans, Alexios was able to curb the Byzantine decline and begin the military, financial, and territorial recovery known as the Komnenian restoration. His appeals to Western Europe for help against the Turks was the catalyst that sparked the First Crusade. (Full article...)
Underdrawing of Basil I in the Paris Gregory, c. 879–883
Basil I, nicknamed "the Macedonian" (Greek: Βασίλειος ὁ Μακεδών, translit.Basíleios ō Makedṓn; 811 – 29 August 886), was Byzantine emperor from 867 to 886. Born a lowly peasant in the theme of Macedonia, he rose to prominence in the imperial court after entering into the service of Theophilitzes, a relative of Emperor Michael III (r. 842–867). He was given a fortune by the wealthy Danielis and gained Michael's favour, whose mistress he married on his emperor's orders. In 866, Michael proclaimed him co-emperor, but Basil ordered his assassination the next year, thus installing himself as sole ruler of the empire. Despite his humble origins, he showed great ability in running the affairs of state, and founded the Macedonian dynasty. He was succeeded upon his death by his son (perhaps actually Michael III's son) Leo VI. (Full article...)
Leo III the Isaurian (Greek: Λέων ὁ Ἴσαυρος, romanized: Leōn ho Isauros; Latin: Leo Isaurus; c. 685 – 18 June 741), also known as the Syrian, was Byzantine Emperor from 717 until his death in 741 and founder of the Isaurian dynasty. He put an end to the Twenty Years' Anarchy, a period of great instability in the Byzantine Empire between 695 and 717, along with bringing an end to the continual defeats and territorial losses the Byzantines had suffered during the seventh century, marked by the rapid succession of several emperors to the throne. He also successfully defended the Empire against the invading Umayyads and forbade the veneration of icons. (Full article...)

He served as grand domestic under Andronikos III Palaiologos and regent for John V Palaiologos before reigning as Byzantine emperor in his own right from 1347 to 1354. Deposed by his former ward, he was forced to retire to a monastery under the name Joasaph Christodoulos (Greek: Ἰωάσαφ Χριστόδουλος) and spent the remainder of his life as a monk and historian. At age 90 or 91 at his death, he was the longest-lived of the Roman emperors. (Full article...)
His reign was marked by the ambitious but only partly realized renovatio imperii, or "restoration of the Empire". This ambition was expressed by the partial recovery of the territories of the defunct Western Roman Empire. His general, Belisarius, swiftly conquered the Vandal Kingdom in North Africa. Subsequently, Belisarius, Narses, and other generals conquered the Ostrogothic kingdom, restoring Dalmatia, Sicily, Italy, and Rome to the empire after more than half a century of rule by the Ostrogoths. The praetorian prefect Liberius reclaimed the south of the Iberian Peninsula, establishing the province of Spania. These campaigns re-established Roman control over the western Mediterranean, increasing the Empire's annual revenue by over a million solidi. During his reign, Justinian also subdued the Tzani, a people on the east coast of the Black Sea that had never been under Roman rule before. He engaged the Sasanian Empire in the east during Kavad I's reign, and later again during Khosrow I's reign; this second conflict was partially initiated due to his ambitions in the west.

Leo Sgouros (Greek: Λέων Σγουρός), Latinized as Leo Sgurus, was a Greek independent lord in the northeastern Peloponnese in the early 13th century. The scion of the magnate Sgouros family, he succeeded his father as hereditary lord in the region of Nauplia. Taking advantage of the disruption caused by the Fourth Crusade, he made himself independent, one of several local rulers that appeared throughout the Byzantine Empire during the final years of the Angeloi dynasty. He expanded his domain into Corinthia and Central Greece, eventually marrying the daughter of former Byzantine emperorAlexios III Angelos (r. 1195–1203). His conquests, however, were short-lived, as the Crusaders forced him back into the Peloponnese. Blockaded in his stronghold on the Acrocorinth, he committed suicide in 1208. (Full article...)

Miniature from the Madrid Skylitzes version of the chronicle of John Skylitzes depicting Thomas, on horseback and dressed as a Byzantine emperor, negotiating with the Arabs. The rebellion of Thomas is one of the most richly illustrated episodes in the chronicle.
An army officer of Slavic origin from the Pontus region (now north-eastern Turkey), Thomas rose to prominence, along with the future emperors Michael II and Leo V the Armenian (r. 813–820), under the protection of general Bardanes Tourkos. After Bardanes' failed rebellion in 803, Thomas fell into obscurity until Leo V's rise to the throne, when Thomas was raised to a senior military command in central Asia Minor. After the murder of Leo and usurpation of the throne by Michael the Amorian, Thomas revolted, claiming the throne for himself. Thomas quickly secured support from most of the themes (provinces) and troops in Asia Minor, defeated Michael's initial counter-attack and concluded an alliance with the Abbasid Caliphate. After winning over the maritime themes and their ships as well, he crossed with his army to Europe and laid siege to Constantinople. The imperial capital withstood Thomas's attacks by land and sea, while Michael II called for help from the Bulgarian ruler khanOmurtag. Omurtag attacked Thomas's army, but although repelled, the Bulgarians inflicted heavy casualties on Thomas's men, who broke and fled when Michael took to the field a few months later. Thomas and his supporters sought refuge in Arcadiopolis, where he was soon blockaded by Michael's troops. In the end, Thomas's supporters surrendered him in exchange for a pardon, and he was executed. (Full article...)
Maurice's reign was troubled by almost constant warfare. After he became emperor, he brought the war with Sasanian Persia to a victorious conclusion. The empire's eastern border in the South Caucasus was vastly expanded and, for the first time in nearly two centuries, the Romans were no longer obliged to pay the Persians thousands of pounds of gold annually for peace.

Gold solidus struck during the revolt of the Heraclii, depicting Heraclius the Elder and his son, the future Emperor Heraclius, wearing consular robes.
Heraclius the Elder (Greek: Ἡράκλειος, Herákleios; died 610) was a Byzantine general and the father of Byzantine emperor Heraclius (r. 610–641). Generally considered to be of Armenian origin, Heraclius the Elder distinguished himself in the war against the Sassanid Persians in the 580s. As a subordinate general (or hypostrategos), Heraclius served under the command of Philippicus during the Battle of Solachon and possibly served under Comentiolus during the Battle of Sisarbanon. Circa 595, Heraclius the Elder is mentioned as a magister militum per Armeniam sent by Emperor Maurice (r. 582–602) to quell an Armenian rebellion led by Samuel Vahewuni and Atat Khorkhoruni. Circa 600, he was appointed as the Exarch of Africa and in 608, he rebelled with his son against the usurper Phocas (r. 602–610). Using North Africa as a base, the younger Heraclius managed to overthrow Phocas, beginning the Heraclian dynasty, which would rule Byzantium for a century. Heraclius the Elder died soon after receiving news of his son's accession to the Byzantine throne. (Full article...)

Constantine VII crowned by Christ, detail of an ivory plaque, Pushkin Museum, AD 945
Most of his reign was dominated by co-regents: from 913 until 919 he was under the regency of his mother, while from 920 until 945 he shared the throne with Romanos Lekapenos, whose daughter Helena he married, and his sons. Constantine VII is best known for the Geoponika (τά γεοπονικά), an important agronomic treatise compiled during his reign, and three, perhaps four, books; De Administrando Imperio (bearing in Greek the heading Πρὸς τὸν ἴδιον υἱὸν Ῥωμανόν), De Ceremoniis (Περὶ τῆς Βασιλείου Τάξεως), De Thematibus (Περὶ θεμάτων Άνατολῆς καὶ Δύσεως), and Vita Basilii (Βίος Βασιλείου), though his authorship of the Vita Basilii is not certain.

Theophilos (Greek: Θεόφιλος, romanized: Theóphilos; Latin: Theophilus, c. 812 – 20 January 842) was the Byzantine Emperor from 829 until his death in 842. He was the second emperor of the Amorian dynasty and the last emperor to support iconoclasm. Theophilos personally led the armies in his long war against the Arabs, beginning in 831.

Born in Naissus, Dacia Mediterranea (now Niš, Serbia), he was the son of Flavius Constantius, a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy. His mother, Helena, was a Greek woman of low birth, probably from Asia Minor in modern Turkey. Later canonised as a saint, she is traditionally credited for the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius. He began his career by campaigning in the eastern provinces (against the Persians) before being recalled in the west (in AD 305) to fight alongside his father in the province of Britannia. After his father's death in 306, Constantine was acclaimed as augustus (emperor) by his army at Eboracum (York, England). He eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324. (Full article...)

Alexios Doukas Philanthropenos (Greek: Ἀλέξιος Δούκας Φιλανθρωπηνός) was a Byzantine nobleman and notable general. A relative of the ruling Palaiologos dynasty, he was appointed commander-in-chief in Asia Minor in 1293 and for a time re-established the Byzantine position there, scoring some of the last Byzantine successes against the Turkish beyliks. In 1295 he rose up in revolt against Andronikos II Palaiologos, but was betrayed and blinded. Nothing is known of him until 1323, when he was pardoned by Andronikos II and sent again against the Turks, relieving a siege of Philadelphia, allegedly by his mere appearance. He was then named briefly governor of Lesbos in 1328, and again in 1336, when he recovered the island's capital from Latin occupation. He ruled the island thereafter, probably until his death in the 1340s. (Full article...)
Heraclius's reign was marked by several military campaigns. The year Heraclius came to power, the empire was threatened on multiple frontiers. Heraclius immediately took charge of the Byzantine–Sasanian War of 602–628. The first battles of the campaign ended in defeat for the Byzantines; the Persian army fought their way to the Bosphorus but Constantinople was protected by impenetrable walls and a strong navy, and Heraclius was able to avoid total defeat. Soon after, he initiated reforms to rebuild and strengthen the military. Heraclius drove the Persians out of Asia Minor and pushed deep into their territory, defeating them decisively in 627 at the Battle of Nineveh. The Persian Shah Khosrow II was overthrown and executed by his son Kavad II, who soon sued for a peace treaty, agreeing to withdraw from all occupied territory. This way peaceful relations were restored to the two deeply strained empires. (Full article...)
Photios is widely regarded as the most powerful and influential church leader of Constantinople subsequent to John Chrysostom's archbishopric around the turn of the fifth century. He is also viewed as the most important intellectual of his time – "the leading light of the ninth-century renaissance". He was a central figure in both the conversion of the Slavs to Christianity and the Photian schism, and is considered "[t]he great systematic compiler of the Eastern Church, who occupies a similar position to that of Gratian in the West," and whose "collection in two parts...formed and still forms the classic source of ancient Church Law for the Greek Church."

Symeon the New Theologian (Greek: Συμεὼν ὁ Νέος Θεολόγος; 949–1022) was an Eastern Orthodox monk and poet who was the last of three saints canonized by the Eastern Orthodox Church and given the title of "Theologian" (along with John the Apostle and Gregory of Nazianzus). "Theologian" was not applied to Symeon in the modern academic sense of theological study; the title was designed only to recognize someone who spoke from personal experience of the vision of God. One of his principal teachings was that humans could and should experience theoria (literally "contemplation," or direct experience of God).
Symeon was born into the Byzantine nobility and given a traditional education. At age fourteen he met Symeon the Studite, a renowned monk of the Monastery of Stoudios in Constantinople, who convinced him to give his own life to prayer and asceticism under the elder Symeon's guidance. By the time he was thirty, Symeon the New Theologian became the abbot of the Monastery of Saint Mamas, a position he held for twenty-five years. He attracted many monks and clergy with his reputation for sanctity, though his teachings brought him into conflict with church authorities, who would eventually send him into exile. His most well known disciple was Nicetas Stethatos who wrote the Life of Symeon. (Full article...)
Constantine V (Greek: Κωνσταντῖνος, translit.Kōnstantīnos; Latin: Constantinus; July 718 – 14 September 775) was Byzantine emperor from 741 to 775. His reign saw a consolidation of Byzantine security from external threats. As an able military leader, Constantine took advantage of civil war in the Muslim world to make limited offensives on the Arab frontier. With this eastern frontier secure, he undertook repeated campaigns against the Bulgars in the Balkans. His military activity, and policy of settling Christian populations from the Arab frontier in Thrace, made Byzantium's hold on its Balkan territories more secure.
Religious strife and controversy was a prominent feature of his reign. His fervent support of Iconoclasm and opposition to monasticism led to his vilification by later Byzantine historians and writers, who denigrated him with the nicknames "the Dung-Named" (Greek: Κοπρώνυμος, translit.Koprónimos; Latin: Copronymus), because he allegedly defaecated during his baptism, similarly "Anointed with Urine" (Greek: Οὐραλύφιος, translit.Ouralýphios; Latin: Uralyphius), and "the Equestrian" (Greek: Καβαλλινος, translit.Kaballinos; Latin: Caballinus), referencing the excrement of horses.

15th-century portrait of Constantine XI (from a codex containing a copy of the Extracts of History by Joannes Zonaras)
Constantine was the fourth son of Emperor Manuel II Palaiologos and Helena Dragaš, the daughter of Serbian ruler Konstantin Dejanović. Little is known of his early life, but from the 1420s onward, he is repeatedly demonstrated to have been a skilled general. Based on his career and surviving contemporary sources, Constantine appears to have been primarily a soldier. This does not mean that Constantine was not also a skilled administrator: he was trusted and favored to such an extent by his older brother, Emperor John VIII Palaiologos, that he was designated as regent twice during John VIII's journeys away from Constantinople in 1423–1424 and 1437–1440. In 1427–1428, Constantine and John fended off an attack on the Morea (the Peloponnese) by Carlo I Tocco, ruler of Epirus, and in 1428 Constantine was proclaimed Despot of the Morea and ruled the province together with his older brother Theodore and his younger brother Thomas. Together, they extended Roman rule to cover almost the entire Peloponnese for the first time since the Fourth Crusade more than two hundred years before and rebuilt the ancient Hexamilion wall, which defended the peninsula from outside attacks. Although ultimately unsuccessful, Constantine personally led a campaign into Central Greece and Thessaly in 1444–1446, attempting to extend Byzantine rule into Greece once more. (Full article...)

Icon of St. Gregory the Theologian, fresco from Kariye Camii in Istanbul, Turkey
Gregory of Nazianzus (Greek: Γρηγόριος ὁ Ναζιανζηνός, romanized: Grēgorios ho Nazianzēnos; c. 329 – 25 January 390), also known as Gregory the Theologian or Gregory Nazianzen, was a 4th-century archbishop of Constantinople and theologian. He is widely considered the most accomplished rhetorical stylist of the patristic age. As a classically trained orator and philosopher, he infused Hellenism into the early church, establishing the paradigm of Byzantine theologians and church officials.
Gregory made a significant impact on the shape of Trinitarian theology among both Greek and Latin-speaking theologians, and he is remembered as the "Trinitarian Theologian". Much of his theological work continues to influence modern theologians, especially in regard to the relationship among the three Persons of the Trinity. Along with the brothers Basil the Great and Gregory of Nyssa, he is known as one of the Cappadocian Fathers. (Full article...)
