During the early centuries of the Roman Empire, the western provinces were Latinised, but the eastern parts kept their Hellenistic culture. Constantine I (r. 324–337) legalised Christianity and moved the capital to Constantinople. Theodosius I (r. 379–395) made Christianity the state religion and Greek gradually replaced Latin for official use. The empire adopted a defensive strategy and, throughout its remaining history, experienced recurring cycles of decline and recovery. (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 or Muslim–Byzantine wars were a series of wars from the 7th to 11th centuries between multiple Arab dynasties and the Byzantine Empire. The Muslim Arab Caliphates conquered large parts of the Christian Byzantine empire and unsuccessfully attacked the Byzantine capital of Constantinople. The frontier between the warring states remained almost static for three centuries of frequent warfare, before the Byzantines were able to recapture some of the lost territory.
The conflicts began during the early Muslim conquests under the expansionist Rashidun Caliphate, part of the initial spread of Islam. In the 630s, Rashidun forces from Arabia attacked and quickly overran Byzantium's southern provinces. Syria was captured in 639 and Egypt was conquered in 642. The Exarchate of Africa was gradually captured between 647 and 670. From the 650s onwards, Arab navies entered the Mediterranean Sea, which became a major battleground. Both sides launched raids and counter-raids against islands and coastal settlements. The Rashiduns were succeeded by the Umayyad Caliphate in 661, who over the next fifty years captured Byzantine Cyrenaica and launched repeated raids into Byzantine Asia Minor. Umayyad forces twice placed Constantinople under siege, in 674 to 678 and 717 to 718, but were unable to capture the heavily fortified Byzantine capital. (Full article...)

Hagia Sophia (Turkish: Ayasofya; Ottoman Turkish: آیا صوفیا; Greek: Ἁγία Σοφία, romanized: Hagía Sophía; Latin: Sancta Sapientia; lit.'Holy Wisdom'), officially the Hagia Sophia Grand Mosque (Turkish: Ayasofya-i Kebir Cami-i Şerifi; Ottoman Turkish: آیا صوفیه کبیر جامع شریفى), is a mosque and former church serving as a major cultural and historical site in Istanbul, Turkey. The last of three church buildings to be successively erected on the site by the Eastern Roman Empire, it was completed in AD 537, becoming the world's largest interior space and among the first to employ a fully pendentive dome. It is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture". From its dedication in 360 until 1453 Hagia Sophia served as the cathedral of Constantinople in the Byzantine liturgical tradition, except for the period 1204–1261 when the Latin Crusaders installed their own hierarchy. After the fall of Constantinople in 1453, it served as a mosque, having its minarets added shortly later. The site became a museum in 1935, and was redesignated as a mosque in 2020. In 2024, the upper floor of the mosque began to serve as a museum once again.
Constantinople was besieged by the Arabs in 674–678, in what was the first culmination of the Umayyad Caliphate's expansionist strategy against the Byzantine Empire. Caliph Mu'awiya I, who had emerged in 661 as the ruler of the Muslim Arab empire following a civil war, renewed aggressive warfare against Byzantium after a lapse of some years and hoped to deliver a lethal blow by capturing the Byzantine capital of Constantinople.
As reported by the Byzantine chronicler Theophanes the Confessor, the Arab attack was methodical: in 672–673 Arab fleets secured bases along the coasts of Asia Minor and then installed a loose blockade around Constantinople. They used the peninsula of Cyzicus near the city as a base to spend the winter and returned every spring to launch attacks against the city's fortifications. Finally the Byzantines, under Emperor Constantine IV, destroyed the Arab navy using a new invention, the liquid incendiary substance known as Greek fire. The Byzantines also defeated the Arab land army in Asia Minor, forcing them to lift the siege. The Byzantine victory was of major importance for the survival of the Byzantine state, as the Arab threat receded for a time. A peace treaty was signed soon after, and following the outbreak of another Muslim civil war, the Byzantines even experienced a brief period of ascendancy over the Caliphate. The siege was arguably the first major Arab defeat in 50 years of expansion and temporarily stabilized the Byzantine Empire after decades of war and defeats. (Full article...)

The Arab Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Arab Muslim rule until conquered in turn by the Normans in the 11th century.
Although Sicily had been raided by the Muslim Arabs since the mid-7th century, these raids did not threaten Byzantine control over the island, which remained a largely peaceful backwater. The opportunity for the Aghlabid emirs of Ifriqiya (present-day Tunisia) came in 827, when the commander of the island's fleet, Euphemius, rose in revolt against the Byzantine EmperorMichael II. Defeated by loyalist forces and driven from the island, Euphemius sought the aid of the Aghlabids, an Arab dynasty. The latter regarded this as an opportunity for expansion and for diverting the energies of their own fractious military establishment and alleviating the criticism of the Islamic scholars by championing jihad, and dispatched an army to aid him. Following the Arab landing on the island, Euphemius was quickly sidelined. An initial assault on the island's capital, Syracuse, failed, but the Muslims were able to weather the subsequent Byzantine counter-attack and hold on to a few fortresses. With the aid of reinforcements from Ifriqiya and Umayyad al-Andalus, in 831 they took Palermo, which became the capital of the new Arab-Muslim province. (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...)

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.
In 1201, 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 Zara (Zadar) 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 Byzantine navy was the naval force of the Byzantine Empire. Like the state it served, it was a direct continuation from its Roman predecessor, but played a far greater role in the defence and survival of the state than its earlier iteration. While the fleets of the Roman Empire faced few great naval threats, operating as a policing force vastly inferior in power and prestige to the army, command of the sea became vital to the very existence of the Byzantine state, which several historians have called a "maritime empire".
The first threat to Roman hegemony in the Mediterranean Sea was posed by the Vandals in the 5th century, but their threat was ended by the wars of Justinian I in the 6th century. The re-establishment of a permanently maintained fleet and the introduction of the dromon galley in the same period also marks the point when the Byzantine navy began departing from its late Roman roots and developing its own characteristic identity. This process would be furthered with the onset of the early Muslim conquests in the 7th century. Following the loss of the Levant and later Africa, the Mediterranean was transformed from a "Roman lake" into a battleground between the Byzantines and a series of Muslim states. In this struggle, the Byzantine fleets were critical, not only for the defence of the Empire's far-flung possessions around the Mediterranean basin, but also for repelling seaborne attacks against the imperial capital of Constantinople itself. Through the use of the newly invented "Greek fire", the Byzantine navy's best-known and feared secret weapon, Constantinople was saved from several sieges and numerous naval engagements resulted in Byzantine victories.

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 Byzantine Iconoclasm (Ancient Greek: Εἰκονομαχία, romanized: Eikonomachía, lit. 'image struggle', 'war on icons') are 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...)

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. The concept of the hospital appeared in Byzantine Empire as an institution to offer medical care and possibility of a cure for the patients because of the ideals of Christian charity.
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...)

The Byzantine Rite, also known as the Greek Rite or the Rite of Constantinople, is a liturgical rite that is identified with the wide range of cultural, devotional, and canonical practices that developed in the Eastern Christian church of Constantinople.
The canonical hours are extended and complex, lasting about eight hours (longer during Great Lent) but are abridged outside of large monasteries. An iconostasis, a partition covered with icons, separates the area around the altar from the nave. The sign of the cross, accompanied by bowing, is made very frequently, e.g., more than a hundred times during the divine liturgy, and there is prominent veneration of icons, a general acceptance of the congregants freely moving within the church and interacting with each other, and distinctive traditions of liturgical chanting.

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.

The Byzantine Empire was ruled by emperors of the dynasty of Heraclius between 610 and 711 AD. The Heraclians presided over a period of cataclysmic events that were a watershed in the history of the Empire and the world. Heraclius, the founder of his dynasty, was of Armenian and Cappadocian (Greek) origin. At the beginning of the dynasty, the Empire's culture was still essentially Ancient Roman, dominating the Mediterranean and harbouring a prosperous late antique urban civilization. This world was shattered by successive invasions, which resulted in extensive territorial losses, financial collapse and plagues that depopulated the cities, while religious controversies and rebellions further weakened the Empire.
By the dynasty's end, the Empire had been transformed into a different state structure: now known in historiography as medieval Byzantine rather than (Ancient) Roman, a chiefly agrarian, military-dominated society that was engaged in a lengthy struggle with the MuslimRashidun Caliphate and successor Umayyad Caliphate. However, the Empire during this period became also far more homogeneous, being reduced to its mostly Greek-speaking and firmly Chalcedonian core territories, which enabled it to weather these storms and enter a period of stability under the successor Isaurian dynasty.

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, Carlo I Tocco, Count Palatine of Cephalonia and Zakynthos, 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 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 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...)
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 troops joined in the pursuit of the fleeing Normans, but became separated from the main force and were massacred. Norman knights attacked the Byzantine centre and routed it, causing the bulk of the Byzantine army to rout. (Full article...)
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.
Founded by the Laskaris family, it lasted from 1204 to 1261, when the Nicenes restored the Byzantine Empire after they recaptured Constantinople. Thus, the Nicene Empire is seen as a direct continuation of the Byzantine Empire, as it fully assumed the traditional titles and government of the Byzantines in 1205. (Full article...)
Born in Naissus, a city located in the province of Moesia Superior (now Niš, Serbia), Constantine was the son of Flavius Constantius, a Roman army officer from Moesia Superior, who would become one of the four emperors of the Tetrarchy. His mother, Helena, was a woman of low birth, probably from Bithynia. Later canonised as a saint, she is credited for the conversion of her son in some traditions, though others believe that Constantine converted her. Constantine was an Illyrian and part of the Illyrian Emperors that ruled the Roman Empire. He served with distinction under emperors Diocletian and Galerius. He began his career by campaigning in the eastern provinces against the Persians, before being recalled to the west in AD 305 to fight alongside his father in the province of Britannia. After his father's death in 306, Constantine was proclaimed as augustus (emperor) by his army at Eboracum (York, England). He eventually emerged victorious in the civil wars against the emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324. (Full article...)

A mosaic in Hagia Sophia showing Leo VI paying homage to Christ
Leo VI, also known as Leothe Wise (Greek: Λέων ὁ Σοφός, romanized: Léōn ho Sophós; 19 September 866 – 11 May 912), was Byzantine Emperor from 886 to 912. The second ruler of the Macedonian dynasty (although his parentage is unclear), he was very well read, leading to his epithet. During his reign, the renaissance of letters, begun by his predecessor Basil I, continued; but the empire also saw several military defeats in the Balkans against Bulgaria and against the Arabs in Sicily and the Aegean. His reign also witnessed the formal discontinuation of several ancient Roman institutions, such as the separate office of Roman consul. (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 BulgarianKhanOmurtag. 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...)

An Orthodox icon of Saint Symeon
Saint Symeon the New Theologian (Greek: Συμεὼν ὁ Νέος Θεολόγος; 949–1022) was an Eastern Orthodox monk and poet who was one of the four saints canonized by the Eastern Orthodox Church and given the title of "Theologian" (along with John the Apostle, Gregory of Nazianzus, and Saint Hesychius the Priest of Jerusalem). "Theologian" was not applied to Symeon in the modern academic sense of theological study; the title was intended 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...)
Leo III the Isaurian (Greek: Λέων ὁ Ἴσαυρος, romanized: Léōn ho Isauros; c. 685 – 18 June 741), also known as the Syrian, was the founder and first Byzantine emperor of the Isaurian dynasty from 717 until his death in 741. He put an end to the Twenty Years' Anarchy, a period of great instability in the Byzantine Empire between 695 and 717, marked by the rapid succession of several emperors to the throne, along with ending the continual defeats and territorial losses the Byzantines had suffered during the 7th century. He also successfully defended the Empire against the invading Umayyads and forbade the veneration of icons. (Full article...)
John has been assessed as the greatest of the Komnenian emperors. This view became entrenched due to its espousal by George Ostrogorsky in his influential book History of the Byzantine State, where John is described as a ruler who, "... combined clever prudence with purposeful energy ... and [was] high principled beyond his day." In the course of the quarter-century of his reign, John made alliances with the Holy Roman Empire in the west, decisively defeated the Pechenegs, Hungarians and Serbs in the Balkans, and personally led numerous campaigns against the Turks in Asia Minor. John's campaigns fundamentally changed the balance of power in the east, forcing the Turks onto the defensive; they also led to the recapture of many towns, fortresses and cities across the Anatolian peninsula. In the southeast, John extended Byzantine control from the Maeander in the west all the way to Cilicia and Tarsus in the east. In an effort to demonstrate the Byzantine ideal of the emperor's role as the leader of the Christian world, John marched into MuslimSyria at the head of the combined forces of Byzantium and the Crusader states; yet despite the great vigour with which he pressed the campaign, John's hopes were disappointed by the evasiveness of his Crusader allies and their reluctance to fight alongside his forces.

Michael I Komnenos Doukas, Latinized as Comnenus Ducas (Greek: Μιχαήλ Κομνηνός Δούκας, romanized: Mikhaēl Komnēnos Doukas), and in modern sources often recorded as Michael I Angelos, a name he never used, was the founder and first ruler of the Despotate of Epirus from c. 1205 until his assassination in 1214/15.
Born c. 1170, Michael was a descendant of Alexios I Komnenos and a cousin of emperors Isaac II Angelos and Alexios III Angelos. He began his public career in 1190, as a hostage to the Third Crusade, and went on to serve as governor of the province of Mylasa and Melanoudion in the 1190s and again in c. 1200/01. During the latter tenure he rebelled against Alexios III but was defeated and forced to flee to the Seljuk Turks. In the aftermath of the sack of Constantinople by the Fourth Crusade in 1204, he attached himself to Boniface of Montferrat. Soon, however, he abandoned the Crusader leader and went to Epirus, where he established himself as ruler, apparently through marriage with the daughter or widow of a local magnate. (Full article...)
It was also at this time that the focus of the Byzantine military shifted to the Balkans, against the Bulgarians, leaving the Anatolian frontier neglected. His successors could not compensate for this change of focus, and both the Arsenite schism and two civil wars which occurred from 1321–1328 and 1341–1347 undermined further efforts toward territorial consolidation and recovery, draining the empire's strength, economy, and resources. Regular conflict between Byzantine successor states such as Trebizond, Epirus, Bulgaria and Serbia resulted in permanent fragmentation of former Byzantine territory and opportunity for increasingly successful conquests of expansive territories by post-SeljukAnatolian beyliks, most notably that of Osman, later called the Ottoman Empire.

Aelia Eudocia Augusta (/ˈiːliəjuːˈdoʊʃəɔːˈɡʌstə/; Ancient Greek: Αιλία Ευδοκία Αυγούστα; c. 400 – 460 AD), also called Saint Eudocia, was an Eastern Roman empress by marriage to Emperor Theodosius II (r. 408–450). Daughter of an Athenian philosopher, she was also a poet, whose works include Homerocentones, or Homeric retellings of Biblical stories. After an estrangement with Theodosius, she permanently settled in Jerusalem, where she supported the local population. (Full article...)
Belisarius (Latin pronunciation:[bɛ.lɪˈsaː.ri.ʊs]; Greek: Βελισάριος; c. 500 – March 565) was a military commander of the Byzantine Empire under Emperor Justinian I. Belisarius was instrumental in the reconquest of much of the Mediterranean territory belonging to the former Western Roman Empire, which had been lost less than a century prior. He is considered one of the greatest military commanders in history and in Byzantium.
One of the defining features of Belisarius' career was his success despite varying levels of available resources. He is frequently cited as being among the "Last of the Romans". He conquered the Vandal Kingdom of North Africa in the Vandalic War in nine months and conquered much of Italy during the Gothic War. He also defeated the Vandal armies in the battle of Ad Decimum and played an important role at Tricamarum, compelling the Vandal king, Gelimer, to surrender. During the Gothic War, despite being significantly outnumbered, he and his troops recaptured the city of Rome and then held out against great odds during the siege of Rome. (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.

Theophilos was well-educated in the imperial household but upon his accession to the throne was met with the dual threat of the Abbasid Caliphate in Asia Minor and the Aghlabids in Sicily. He personally led the armies in his long war against both the Abbasid Caliphate and the Aghlabids in Sicily, beginning in 831. He won fleeting victories but the retaliation of Caliph al-Mu'tasim (r. 833–842) was devastating, as was most humiliating in the Sack of Amorion in 838, the ancestral home of Theophilos' Amorian dynasty. Internal strife within the Caliphate allowed the Byzantines to recover. Theophilos engaged in many construction and renovation projects. One of his closest allies was the learned and cosmopolitan John the Grammarian, and they both improved relations with the Caliph and appreciated Arabic culture. He also secured nominal overlordship over the Principality of Serbia, uniting against their common enemy, the First Bulgarian Empire. (Full article...)

Nikephoros Phokas (Greek: Νικηφόρος Φωκᾶς, romanized: Nikēphoros Phōkas; died 895/6 or c. 900), usually surnamed the Elder to distinguish him from his grandson, Emperor Nikephoros II Phokas, was one of the most prominent Byzantine generals of the late 9th century, and the first important member of the Phokas family. As a youth he was taken into the personal retinue of Emperor Basil I the Macedonian, rising quickly to the posts of protostrator and then governor of Charsianon, whence he fought with success against the Arabs. In c. 886 he led a major expedition in southern Italy, where his victories laid the foundation for the Byzantine resurgence in the peninsula. After his return, he was raised to the post of Domestic of the Schools, in effect commander-in-chief of the army, which he led with success against the Arabs in the east and the Bulgarians of Tsar Simeon in the Balkans. He died either in 895/6 or, less likely, sometime c. 900. Contemporaries and later historians lauded him for his military ability and character. Both of his sons later succeeded him as Domestics of the Schools. His grandsons Nikephoros and Leo were likewise distinguished generals, while the former became emperor in 963–969, spearheading the recovery of several lost provinces from the Arabs.

Choniates in an ancient manuscript
Niketas or Nicetas Choniates (Medieval Greek: Νικήτας Χωνιάτης; c. 1155 – 1217), whose actual surname was Akominatos (Ἀκομινάτος), was a Byzantine Greek historian and politician. He accompanied his brother Michael Akominatos to Constantinople from their birthplace Chonae (from which came his nickname, "Choniates" meaning "person from Chonae"). Nicetas wrote a history of the Eastern Roman Empire from 1118 to 1207. (Full article...)

Manuscript miniature, part of double portrait with Empress Maria, Vatican Library
Manuel I Komnenos (Greek: Μανουήλ Κομνηνός, romanized: Manouḗl Komnēnós; 28 November 1118 – 24 September 1180), Latinized as Comnenus, also called Porphyrogenitus (Greek: Πορφυρογέννητος, romanized: Porphyrogénnētos; "born in the purple"), was a Byzantine emperor of the 12th century who reigned over a crucial turning point in the history of Byzantium and the Mediterranean. His reign saw the last flowering of the Komnenian restoration, during which the Byzantine Empire experienced a resurgence of military and economic power and enjoyed a cultural revival.
Eager to restore his empire to its past glories as the great power of the Mediterranean world, Manuel pursued an energetic and ambitious foreign policy. In the process he made alliances with Pope Adrian IV and the resurgent West. He invaded the Norman Kingdom of Sicily, although unsuccessfully, being the last Eastern Roman emperor to attempt reconquests in the western Mediterranean. The passage of the potentially dangerous Second Crusade through his empire was adroitly managed. Manuel established a Byzantine protectorate over the Crusader states of Outremer. Facing Muslim advances in the Holy Land, he made common cause with the Kingdom of Jerusalem and participated in a combined invasion of FatimidEgypt. Manuel reshaped the political maps of the Balkans and the eastern Mediterranean, placing the kingdoms of Hungary and Outremer under Byzantine hegemony and campaigning aggressively against his neighbours both in the west and in the east.

Coin depicting John II Megas Komnenos
John II Megas Komnenos (Ancient Greek: Ἰωάννης Μέγας Κομνηνός, Iōannēs Megas Komnēnos) (c. 1262 – 16 August 1297) was Emperor 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...)
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.

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...)
Basil II Porphyrogenitus (Greek: Βασίλειος Πορφυρογέννητος, romanized: Basíleios Porphyrogénnētos; 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.
Manuel the Armenian (Ancient Greek: Μανουήλ ὁ Ἀρμένιος), was a prominent Byzantine general of Armenian origin, active from c. 810 until his death. After reaching the highest military ranks, a palace conspiracy forced him to seek refuge in the Abbasid court in 829. He returned to Byzantine service the next year, receiving the position of Domestic of the Schools from Emperor Theophilos, who had married his niece Theodora. Manuel remained in the post throughout Theophilos's reign, and reportedly saved the emperor's life in the Battle of Anzen in 838. According to one report, he died on 27 July 838 of wounds received during the battle, but other sources record his survival past this date, ascribing him a major role in the regency that governed the empire after Theophilos's death, and report that he died some time around 860.

Alexios V Doukas (Greek: Ἀλέξιος Δούκας, romanized: Aléxios Doúkās; died December 1204), Latinized as Alexius V Ducas, was Byzantine emperor from February to April 1204, just prior to the sack of Constantinople by the participants of the Fourth Crusade. His family name was Doukas, but he was also known by the nickname Mourtzouphlos or Murtzuphlus (Μούρτζουφλος), referring to either bushy, overhanging eyebrows or a sullen, gloomy character. He achieved power through a palace coup, killing his predecessors in the process. Though he made vigorous attempts to defend Constantinople from the crusader army, his military efforts proved ineffective. His actions won the support of the mass of the populace, but he alienated the elite of the city. Following the fall, sack, and occupation of the city, Alexios V was blinded by his father-in-law, the ex-emperor Alexios III, and later executed by the new Latin regime. He was the last Byzantine emperor to rule in Constantinople until the Byzantine recapture of Constantinople in 1261. (Full article...)

Nikephoros II Phokas on a 15th-century manuscript, Biblioteca Marciana, Venice. The portrait is almost certainly imaginary.
Nikephoros II Phokas (Greek: Νικηφόρος Φωκᾶς, romanized: Nikēphóros Phōkâs; c. 912 – 11 December 969), LatinizedNicephorus II Phocas, was Byzantine emperor from 963 to 969. His career, not uniformly successful in matters of statecraft or of war, nonetheless greatly contributed to the resurgence of the Byzantine Empire during the 10th century. In the east, Nikephoros completed the conquest of Cilicia and retook the islands of Crete and Cyprus, opening the path for subsequent Byzantine incursions reaching as far as Upper Mesopotamia and the Levant; these campaigns earned him the sobriquet "pale death of the Saracens".

... that the Byzantine Empire's weak defenses around the Lycus valley played a pivotal role in the fall of Constantinople?
... that Byzantine general Manuel Kamytzes began a rebellion against his emperor when the latter took advantage of his capture to confiscate his fortune, imprison his family, and refuse to ransom him?
... that in the nocturnal Battle of Kapetron, the Byzantines in the flanks defeated their Seljuk opponents, but on the next morning learned of their Georgian allies' defeat in the centre?
