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.
Hagia Sophia (lit. 'Holy Wisdom'; Turkish: Ayasofya; Greek: Ἁγία Σοφία, romanized: Hagía Sofía; Latin: Sancta Sapientia), officially the Hagia Sophia Grand Mosque (Turkish: Ayasofya-i Kebir Cami-i Şerifi), 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 537 AD. The site was a Chalcedonian church from 360 AD to 1054, an Orthodox church following the Great Schism of 1054, and a Catholic church following the Fourth Crusade. It was reclaimed in 1261 and remained Eastern Orthodox until the fall of Constantinople in 1453. It served as a mosque until 1935, when it became a museum. In 2020, the site once again became a mosque.
The current structure was built by the Byzantine emperorJustinian I as the Christian cathedral of Constantinople for the Byzantine Empire between 532 and 537, and was designed by the GreekgeometersIsidore of Miletus and Anthemius of Tralles. It was formally called the Church of God's Holy Wisdom (Greek: Ναὸς τῆς Ἁγίας τοῦ Θεοῦ Σοφίας, romanized: Naòs tês Hagías toû Theoû Sophías) and upon completion became 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". The present Justinianic building was the third church of the same name to occupy the site, as the prior one had been destroyed in the Nika riots. As the episcopal see of the ecumenical patriarch of Constantinople, it remained the world's largest cathedral for nearly a thousand years, until the Seville Cathedral was completed in 1520. Beginning with subsequent Byzantine architecture, Hagia Sophia became the paradigmatic Orthodox church form, and its architectural style was emulated by Ottoman mosques a thousand years later. It has been described as "holding a unique position in the Christian world" and as an architectural and cultural icon of Byzantine and Eastern Orthodox civilization. (Full article...)

The Eastern Orthodox Church, officially the Orthodox Catholic Church, and also called the Greek Orthodox Church or simply the Orthodox Church, is the second-largest Christian church, with approximately 230 million baptised members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the head of the Catholic Church (the pope). Nevertheless, the Ecumenical Patriarch of Constantinople is recognised by them as primus inter pares ("first among equals"), a title formerly given to the patriarch of Rome. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played an especially prominent role in the history and culture of Eastern and Southeastern Europe.
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...)
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...)

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.

The Great Palace of Constantinople (Greek: Μέγα Παλάτιον, Méga Palátion; Latin: Palatium Magnum), also known as the Sacred Palace (Greek: Ἱερὸν Παλάτιον, Hieròn Palátion; Latin: Sacrum Palatium), was the large imperial Byzantine palace complex located in the south-eastern end of the peninsula now known as Old Istanbul (formerly Constantinople), in modern Turkey. It served as the main imperial residence of the Eastern Roman emperors until 1081 and was the centre of imperial administration for over 690 years. Only a few remnants and fragments of its foundations have survived into the present day. (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 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 Muslim rule until conquered in turn by the Normans in the 11th century.
Although Sicily had been raided by the Muslims 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. 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 al-Andalus, in 831 they took Palermo, which became the capital of the new Muslim province. (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 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.

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.

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...)
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 Despotate of the Morea (Greek: Δεσποτᾶτον τοῦ Μορέως) or Despotate of Mystras (Greek: Δεσποτᾶτον τοῦ Μυστρᾶ) was a province of the Byzantine Empire which existed between the mid-14th and mid-15th centuries. Its territory varied in size during its existence but eventually grew to include almost all the southern Greek peninsula now known as the Peloponnese, which was known as the Morea during the medieval and early modern periods. The territory was usually ruled by one or more sons of the current Byzantine emperor, who were given the title of despotes (in this context it should not be confused with despotism). Its capital was the fortified city of Mystras, near ancient Sparta, which became an important centre of the Palaiologan Renaissance. (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...)
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...)

The first Arab siege of Constantinople in 674–678 was a major conflict of the Arab–Byzantine wars, and the first culmination of the Umayyad Caliphate's expansionist strategy towards the Byzantine Empire, led by Caliph Mu'awiya I. Mu'awiya, 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 proceeded to install 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, managed to destroy 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 the first major Arab defeat in 50 years of expansion and temporarily stabilized the Byzantine Empire after decades of war and defeats. (Full article...)
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger. They saved the city, and the Byzantine Empire with it, during sieges by the Avar–Sassanian coalition, Arabs, Rus', and Bulgars, among others. The fortifications retained their usefulness after the advent of gunpowder siege cannons, which played a part in the city's fall to Ottoman forces in 1453 but were not able to breach its walls.

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.

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 the early summer of 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 Byzantine Empire was ruled by the Isaurian dynasty (or Syrian dynasty) from 717 to 802. The Isaurian emperors were successful in defending and consolidating the empire against the caliphates after the onslaught of the early Muslim conquests, but were less successful in Europe, where they suffered setbacks against the Bulgars, had to give up the Exarchate of Ravenna, and lost influence over Italy and the papacy to the growing power of the Franks.
The Isaurian dynasty is chiefly associated with Byzantine iconoclasm, an attempt to restore divine favour by purifying the Christian faith from excessive adoration of icons, which resulted in considerable internal turmoil. (Full article...)
Mount Athos has been inhabited since ancient times and is known for its long Christian presence and historical monastic traditions, which date back to at least 800 AD during the Byzantine era. Because of its long history of religious importance, the well-preserved agrarian architecture within the monasteries, and the preservation of the flora and fauna around the mountain, the monastic community of Mount Athos was added to the UNESCOWorld Heritage List in 1988.

The sack of Amorium by the Abbasid Caliphate in mid-August 838 was one of the major events in the long history of the Arab–Byzantine Wars. The Abbasid campaign was led personally by the Caliph al-Mu'tasim (r. 833–842), in retaliation to a virtually unopposed expedition launched by the Byzantine emperorTheophilos (r. 829–842) into the Caliphate's borderlands the previous year. Mu'tasim targeted Amorium, an Eastern Roman city in western Asia Minor, because it was the birthplace of the ruling Byzantine dynasty and, at the time, one of Byzantium's largest and most important cities. The caliph gathered an exceptionally large army, which he divided in two parts, which invaded from the northeast and the south. The northeastern army defeated the Byzantine forces under Theophilos at Anzen, allowing the Abbasids to penetrate deep into Byzantine Asia Minor and converge upon Ancyra, which they found abandoned. After sacking the city, they turned south to Amorium, where they arrived on 1 August. Faced with intrigues at Constantinople and the rebellion of the large Khurramite contingent of his army, Theophilos was unable to aid the city.
Amorium was strongly fortified and garrisoned, but a local inhabitant revealed a weak spot in the wall, where the Abbasids concentrated their attack, effecting a breach. Unable to break through the besieging army, Boiditzes, the commander of the breached section, privately attempted to negotiate with the Caliph without notifying his superiors. He concluded a local truce and left his post, which allowed the Arabs to take advantage, enter the city, and capture it. Amorium was systematically destroyed, never to recover its former prosperity. Many of its inhabitants were slaughtered, and the remainder driven off as slaves. Most of the survivors were released after a truce in 841, but prominent officials were taken to the caliph's capital of Samarra and executed years later after refusing to convert to Islam, becoming known as the 42 Martyrs of Amorium.

The Fourth Crusade (November 10, 1202 - April 13, 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...)
A polymath whose fields of interest and contribution included law, theology, philosophy, and music, he was given the by-name of Chrysorroas (Χρυσορρόας, literally "streaming with gold", i.e. "the golden speaker"). He wrote works expounding the Christian faith, and composed hymns which are still used both liturgically in Eastern Christian practice throughout the world as well as in western Lutheranism at Easter.

Married to a Thessalian Vlach woman, John first appears leading Vlach troops alongside his father in the lead-up to the Battle of Pelagonia in 1259. His defection to the camp of Emperor Michael VIII Palaiologos was crucial in the battle, which ended with the crushing defeat of the Epirotes' Latin allies and opened the way for the recovery of Constantinople and the re-establishment of the Byzantine Empire under Palaiologos in 1261. John quickly returned to the side of his father and brother, Nikephoros, and assisted them in recovering Epirus and Thessaly. After Michael II died, John Doukas became ruler of Thessaly with his seat at Neopatras, whence Western chroniclers often erroneously called him "Duke of Neopatras". (Full article...)
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...)
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...)
Manuel I Komnenos (Greek: Μανουήλ Κομνηνός, romanized: Manouḗl Komnēnós; 28 November 1118 – 24 September 1180), Latinized as Comnenus, also called Porphyrogenitus (Greek: Πορφυρογέννητος; "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 had seen a resurgence of its military and economic power and had enjoyed a cultural revival.
Theodosius I (Greek: ΘεοδόσιοςTheodosios; 11 January 347 – 17 January 395), also called Theodosius the Great, was a Roman emperor from 379 to 395. During his reign, he succeeded in a crucial war against the Goths, as well as in two civil wars, and was instrumental in establishing the creed of Nicaea as the orthodox doctrine for Christianity. Theodosius was the last emperor to rule the entire Roman Empire before its administration was permanently split between the West and East.
Born in Hispania, Theodosius was the son of a high-ranking general, Theodosius the Elder, under whose guidance he rose through the ranks of the Roman army. Theodosius held independent command in Moesia in 374, where he had some success against the invading Sarmatians. Not long afterwards, he was forced into retirement, and his father was executed under obscure circumstances. Theodosius soon regained his position following a series of intrigues and executions at Emperor Gratian's court. In 379, after the eastern Roman emperor Valens perished at the Battle of Adrianople against the Goths, Gratian appointed Theodosius as a successor with orders to take charge of the current military emergency. The new emperor's resources, and depleted armies, were not sufficient to drive the invaders out; in 382 the Goths were allowed to settle south of the Danube as autonomous allies of the empire. In 386, Theodosius signed a treaty with the Sasanian Empire which partitioned the long-disputed Kingdom of Armenia and secured a durable peace between the two powers. (Full article...)
Alexios III Megas Komnenos (Greek: Αλέξιος Μέγας Κομνηνός; 5 October 1338 – 20 March 1390), or Alexius III, was Emperor of Trebizond from December 1349 until his death. He is perhaps the best-documented ruler of that country, and his reign is distinguished by a number of religious grants and literary creations.
He was the son of Emperor Basil of Trebizond and his second (and bigamous) wife, Irene of Trebizond. Alexios III was originally named John (Ιωάννης, Iōannēs), and took the name Alexios either in memory of his older brother who had died prematurely or of his paternal grandfather, Emperor Alexios II of Trebizond.

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...)
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...)

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...)

Aelia Eudocia Augusta (/ˈiːliəjuːˈdoʊʃəɔːˈɡʌstə/; Greek: Αιλία Ευδοκία Αυγούστα; c. 401 – 460 AD), also called Saint Eudocia, was an Eastern Roman empress by marriage to Emperor Theodosius II (r. 408–450), and a prominent Greek historical figure in understanding the rise of Christianity during the beginning of the Byzantine Empire. Eudocia lived in a world where Greek paganism and Christianity existed side by side with both pagans and non-orthodox Christians being persecuted. Although Eudocia's work (including the Homeric centos and an epic poem on the martyrdom of St. Cyprian) has been mostly ignored by modern scholars, her poetry and literary work are great examples of how her Christian faith and Greek heritage and upbringing were intertwined, exemplifying a legacy that the Roman Empire left behind on the Christian world.

Nikephoros II Phokas (Greek: Νικηφόρος Φωκᾶς, Nikēphóros Phōkãs; 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".

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...)
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...)

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.

Staurakios (Greek: Σταυράκιος, sometimes Latinized Stauracius; died 3 June 800) was a Byzantine Greekeunuch official, who rose to be one of the most important and influential associates of Byzantine empressIrene of Athens (r. 797–802). He effectively acted as chief minister during her regency for her young son, Emperor Constantine VI (r. 780–797) in 780–790, until overthrown and exiled by a military revolt in favour of the young emperor in 790. Restored to power by Constantine along with Irene in 792, Staurakios aided her in the eventual removal, blinding, and possible murder of her son in 797. His own position thereafter was threatened by the rise of another powerful eunuch, Aetios. Their increasing rivalry, and Staurakios's own imperial ambitions, were only resolved by Staurakios's death.

Peter the Patrician (Latin: Petrus Patricius, Greek: Πέτρος ὁ Πατρίκιος, Petros ho Patrikios; c. 500–565) was a senior Byzantine official, diplomat, and historian. A well-educated and successful lawyer, he was repeatedly sent as envoy to Ostrogothic Italy in the prelude to the Gothic War of 535–554. Despite his diplomatic skill, he was not able to avert war, and was imprisoned by the Goths in Ravenna for a few years. Upon his release, he was appointed to the post of magister officiorum, head of the imperial secretariat, which he held for an unparalleled 26 years. In this capacity, he was one of the leading ministers of Emperor Justinian I (r. 527–565), playing an important role in the Byzantine emperor's religious policies and the relations with Sassanid Persia; most notably he led the negotiations for the peace agreement of 562 that ended the 20-year-long Lazic War. His historical writings survive only in fragments, but provide unique source material on early Byzantine ceremonies and diplomatic issues between Byzantium and the Sassanids. (Full article...)
Justinian II (Latin: Iustinianus; Greek: Ἰουστινιανός, romanized: Ioustinianós; 668/69 – 4 November 711), nicknamed "the Slit-Nosed" (Latin: Rhinotmetus; Greek: ὁ Ῥινότμητος, romanized: ho Rhīnótmētos), was the last Byzantine emperor of the Heraclian dynasty, reigning from 685 to 695 and again from 705 to 711. Like his namesake, Justinian I, Justinian II was an ambitious and passionate ruler who was keen to restore the Roman Empire to its former glories. However, he responded brutally to any opposition to his will and lacked the finesse of his father, Constantine IV. Consequently, he generated enormous opposition to his reign, resulting in his deposition in 695 in a popular uprising. He only returned to the throne in 705 with the help of a Bulgar and Slav army. His second reign was even more despotic than the first, and in 711 he was killed by mutinous soldiers. (Full article...)

Alexios I Megas Komnenos (Greek: Αλέξιος Κομνηνός; Georgian: ალექსი კომნენოსი; c. 1182 – 1 February 1222) or Alexius I Megas Comnenus 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...)

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...)
Irene of Athens (Greek: Εἰρήνη, Eirḗnē; 750/756 – 9 August 803), surname Sarantapechaena (Greek: Σαρανταπήχαινα, Sarantapḗchaina), was Byzantine empress consort to Emperor Leo IV from 775 to 780, regent during the childhood of their son Constantine VI from 780 until 790, co-ruler from 792 until 797, and finally empress regnant and sole ruler of the Eastern Roman Empire from 797 to 802. A member of the politically prominent Sarantapechos family, she was selected as Leo IV's bride for unknown reasons in 768. Even though her husband was an iconoclast, she harbored iconophile sympathies. During her rule as regent, she called the Second Council of Nicaea in 787, which condemned iconoclasm as heretical and brought an end to the first iconoclast period (730–787). Her public figure was very polarizing during her 5 year reign, as most saw it as wrong for a woman to rule solely. Her reign as such made her the first ever empress regnant, ruling in her own right, in Roman and Byzantine imperial history.
The untimely death of her husband caused the throne to actually fall to her, leaving her solely in charge. During her regency with her son, Constantine VI, Irene became very influential in government policies. As Constantine VI reached maturity, he began to move out from under the influence of his mother. In the early 790s, several revolts tried to proclaim him as sole ruler. One of these revolts succeeded, but in 792 Irene was re-established in all imperial powers as co-emperor with Constantine VI. In 797, Irene organized a conspiracy in which her supporters gouged out her son's eyes, maiming him severely. He was imprisoned and probably died shortly afterwards. With him out of the way, Irene proclaimed herself sole ruler. Pope Leo III—already seeking to break links with the Byzantine East—used Irene's alleged unprecedented status as a female ruler of the Roman Empire to proclaim Charlemagne as Emperor of the Romans on Christmas Day of 800 under the pretext that a woman could not rule and so the throne of the Roman Empire was actually vacant. A revolt in 802 overthrew Irene and exiled her to the island of Lesbos, supplanting her on the throne with Nikephoros I. Irene died in exile less than a year later. (Full article...)

Andronikos II Palaiologos (Greek: Ἀνδρόνικος Δούκας Ἄγγελος Κομνηνὸς Παλαιολόγος, romanized: Andrónikos Doúkās Ángelos Komnēnós Palaiologos; 25 March 1259 – 13 February 1332), Latinized as Andronicus II Palaeologus, reigned as Byzantine emperor from 1282 to 1328. His reign marked the beginning of the recently-restored empire's final decline. The Turks conquered most of Byzantium's remaining Anatolian territories, and Andronikos spent the last years of his reign fighting his own grandson in the First Palaiologan Civil War. The war ended in Andronikos' forced abdication in 1328, after which he retired to a monastery for the remainder of his life. (Full article...)
Alexios V Doukas (Greek: Ἀλέξιος Δούκας; 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...)
