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 Christianity as the state religion, 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.
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 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...)

The Empire of Nicaea (Greek: Βασιλεία Ῥωμαίων) or the Nicene Empire was the largest of the three Byzantine Greekrump states founded by the aristocracy of the Byzantine Empire that fled when Constantinople was occupied by Western European and Venetian armed forces during the Fourth Crusade, a military event known as the Sack of Constantinople. Like the other Byzantine rump states that formed due to the 1204 fracturing of the empire, such as the Empire of Trebizond and the Despotate of Epirus, it was a continuation of the eastern half of the Roman Empire that survived well into the medieval period. A fourth state, known in historiography as the Latin Empire, was established by an army of Crusaders and the Republic of Venice after the capture of Constantinople and the surrounding environs.
Founded by the Laskaris family, it lasted from 1204 to 1261, when the Nicenes restored the Byzantine Empire in Constantinople after its recapture. Thus, the Nicene Empire is seen as a direct continuation of the Byzantine Empire, as it fully assumed the traditional titles and government of the Byzantines in 1205. (Full article...)

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

The 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 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...)

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

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

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...)
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 richest interiors were finished with thin plates of marble or coloured and patterned stone. Some of the columns were also made of marble. Other widely used materials were bricks and stone. Mosaics made of stone or glass tesserae were also elements of interior architecture. Precious wood furniture, like beds, chairs, stools, tables, bookshelves and silver or golden cups with beautiful reliefs, decorated Byzantine interiors. (Full article...)

A Hodegetria, or Virgin Hodegetria, is an iconographic depiction of the Theotokos (Virgin Mary) holding the Child Jesus at her side while pointing to him as the source of salvation for humankind. The Virgin's head usually inclines towards the child, who raises his hand in a blessing gesture. Metals are often used to draw attention to young Christ, reflecting light and shining in a way to embody divinity. In the Western Church this type of icon is sometimes called Our Lady of the Way.
The most venerated icon of the Hodegetria type, regarded as the original, was displayed in the Monastery of the Panaghia Hodegetria in Constantinople, which was built specially to contain it. Unlike most later copies it showed the Theotokos standing full-length. It was said to have been brought back from the Holy Land by Eudocia, the wife of emperor Theodosius II (408–450), and to have been painted by Saint Luke the evangelist, the attributed author of the Gospel of Luke. The icon was double-sided, with a crucifixion on the other side, and was "perhaps the most prominent cult object in Byzantium". (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 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 Empireunder the Macedonian dynasty underwent a revival during the late 9th, 10th, and early 11th centuries. Under the Macedonian emperors, the empire gained control over the Adriatic Sea, Southern Italy, and all of the territory of the TsarSamuil of Bulgaria. The Macedonian dynasty was characterised by a cultural revival in spheres such as philosophy and the arts, and has been dubbed the "Golden Age" of Byzantium.
The cities of the empire expanded, and affluence spread across the provinces because of the newfound security. The population rose, and production increased, stimulating new demand for trade. (Full article...)
A group of Andalusian exiles led by Abu Hafs Umar al-Iqritishi conquered Crete in either 824 or 827/828, and established an independent Islamic state. The Byzantines launched a campaign that took most of the island back in 842-43 under Theoktistos, but the reconquest was not completed and would soon be reversed. Later attempts by the Byzantine Empire to recover the island failed, and for the approximately 135 years of its existence, the emirate was one of the major foes of Byzantium. Crete commanded the sea lanes of the Eastern Mediterranean and functioned as a forward base and haven for Muslim corsair fleets that ravaged the Byzantine-controlled shores of the Aegean Sea. The emirate's internal history is less well known, but all accounts point to considerable prosperity deriving not only from piracy but also from extensive trade and agriculture. The emirate was brought to an end by Nikephoros Phokas, who successfully campaigned against it in 960–961, re-annexing the island to the Byzantine Empire. (Full article...)
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.

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...)

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 an 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...)

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

Bardanes, nicknamed Tourkos, "the Turk" (Greek: Βαρδάνης ὁ Τοῦρκος, romanized: Bardanēs ho Tourkos, fl. 795–803), was a Byzantine general who launched an unsuccessful rebellion against Emperor Nikephoros I (r. 802–811) in 803. Although a major supporter of Byzantine empressIrene of Athens (r. 797–802), soon after her overthrow he was appointed by Nikephoros as commander-in-chief of the Anatolian armies. From this position, he launched a revolt in July 803, probably in opposition to Nikephoros's economic and religious policies. His troops marched towards Constantinople, but failed to win popular support. At this point, some of his major supporters deserted him and, reluctant to engage the loyalist forces in battle, Bardanes gave up and chose to surrender himself. He retired as a monk to a monastery he had founded. There he was blinded, possibly on Nikephoros's orders. (Full article...)
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...)
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...)

Theodora was the youngest daughter of Emperor Constantine VIII. After Theodora's father died in 1028, her older sister Zoë co-ruled with her husbands Romanos III and Michael IV, keeping Theodora closely watched.

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 – like his brother Michael Akominatos, whom he accompanied 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...)
Alexios Komnenos (Greek: Ἀλέξιος Κομνηνός; c. 1135/42 – after 1182) was a Byzantine aristocrat and courtier. A son of Andronikos Komnenos and nephew of Emperor Manuel I Komnenos, he rose to the high rank of prōtostratōr in 1167. In 1176 he participated in the Myriokephalon campaign where, following the death of his older brother John, he was raised to the titles of prōtosebastos and prōtovestiarios. Following Manuel's death in 1180, he won the favour, and reportedly became the lover, of Empress-dowagerMaria of Antioch. Through her he ruled the Byzantine Empire for two years as de facto regent of the underage emperor Alexios II Komnenos. The aristocracy challenged his dominance, led by the princess Maria Komnene, who plotted to assassinate the prōtosebastos. The plot was discovered and most conspirators arrested, but Maria and her husband fled to the Hagia Sophia, protected by Patriarch Theodosios Borradiotes and the common people of Constantinople.
Mounting tensions resulted in a popular uprising against Alexios' regime on 2 May 1181, (modern scholars have proposed other dates as well), which ended in a mutual reconciliation. His power shaken, the prōtosebastos reacted by punishing Borradiotes for his role in the affair. Overwhelming opposition, both among the people and the aristocracy, forced him to recall Borradiotes soon after. These events left Alexios in poor shape to oppose the advance of the adventurer Andronikos I Komnenos, who moved against Constantinople from the east. The generals dispatched against Andronikos were defeated or defected, and the usurper entered the city in April 1182. The prōtosebastos Alexios was deposed, publicly humiliated, and mutilated. His fate thereafter is not known. (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...)
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...)
Basil II Porphyrogenitus (Greek: Βασίλειος ΠορφυρογέννητοςBasileios Porphyrogennetos; 958 – 15 December 1025), nicknamed the Bulgar Slayer (Greek: ὁ Βουλγαροκτόνος, ho Boulgaroktónos), was the senior Byzantine emperor from 976 to 1025. He and his brother Constantine VIII were crowned before their father Romanos II died in 963, but they were too young to rule. The throne thus went to two generals, Nikephoros Phokas (r. 963–969) and John Tzimiskes (r. 969–976) before Basil became senior emperor, though his influential great-uncle Basil Lekapenos remained as the de facto ruler until 985. His reign of 49 years and 11 months was the longest of any Roman emperor.
Underdrawing of Basil I in the Paris Gregory, c. 879–883
Basil I, nicknamed "the Macedonian" (Greek: Βασίλειος ὁ Μακεδών, translit.Basíleios ō Makedṓn; 811 – 29 August 886), was Byzantine emperor from 867 to 886. Born a lowly peasant in the theme of Macedonia, he rose to prominence in the imperial court after entering into the service of Theophilitzes, a relative of Emperor Michael III (r. 842–867). He was given a fortune by the wealthy Danielis and gained Michael's favour, whose mistress he married on his emperor's orders. In 866, Michael proclaimed him co-emperor, but Basil ordered his assassination the next year, thus installing himself as sole ruler of the empire. Despite his humble origins, he showed great ability in running the affairs of state, and founded the Macedonian dynasty. He was succeeded upon his death by his son (perhaps actually Michael III's son) Leo VI. (Full article...)

Anna Dalassene (Greek: Ἄννα Δαλασσηνή; ca. 1025/30 – 1 November 1100/02) was an important Byzantine noblewoman who played a significant role in the rise to power of the Komnenoi in the eleventh century. She exercised great influence over her son, the Emperor Alexios I Komnenos, who gave her the title Augusta. She also administered the empire as regent during his many absences from Constantinople on long military campaigns during the early part of his reign. As empress-mother, she exerted more influence and power than the empress-consort, Irene Doukaina, a woman whom she hated because of past intrigues with the Doukai. (Full article...)

John Kourkouas (Greek: Ἰωάννης Κουρκούας, romanized: Ioannes Kourkouas, fl. c. 900–946), also transliterated as Kurkuas or Curcuas, was one of the most important generals of the Byzantine Empire. His success in battles against the Muslim states in the East reversed the course of the centuries-long Arab–Byzantine wars and set the stage for Byzantium's eastern conquests later in the century.
Kourkouas belonged to a family of Armenian descent that produced several notable Byzantine generals. As commander of an imperial bodyguard regiment, Kourkouas was among the chief supporters of EmperorRomanos I Lekapenos (r. 920–944) and facilitated the latter's rise to the throne. In 923, Kourkouas was appointed commander-in-chief of the Byzantine armies along the eastern frontier, facing the Abbasid Caliphate and the semi-autonomous Muslim border emirates. He kept this post for more than twenty years, overseeing decisive Byzantine military successes that altered the strategic balance in the region. (Full article...)

Depiction from a contemporary portrait mosaic in the Basilica of San Vitale, Ravenna
Manuel the Armenian (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.

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.

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...)

Coin of Harald as the sole Norwegian king, "ARALD[us] REX NAR[vegiae]". Imitation of a type of Edward the Confessor.
Harald Sigurdsson (Old Norse: Haraldr Sigurðarson; c. 1015 – 25 September 1066), also known as Harald III of Norway and given the epithet Hardrada (harðráði; modern Norwegian: Hardråde, roughly translated as "stern counsel" or "hard ruler") in the sagas, was King of Norway from 1046 to 1066. Additionally, he unsuccessfully claimed both the Danish throne until 1064 and the English throne in 1066. Before becoming king, Harald had spent around fifteen years in exile as a mercenary and military commander in Kievan Rus' and as a chief of the Varangian Guard in the Byzantine Empire. In his chronicle, Adam of Bremen called him the "Thunderbolt of the North".
In 1030 aged fifteen, Harald fought in the Battle of Stiklestad together with his half-brother Olaf Haraldsson (later Saint Olaf). Olaf sought to reclaim the Norwegian throne, which he had lost to the Danish king Cnut the Great two years prior. In the battle, Olaf and Harald were defeated by forces loyal to Cnut, and Harald was forced into exile to Kievan Rus' (the sagas' Garðaríki). Thereafter, he was in the army of Grand Prince Yaroslav the Wise, becoming captain, until he moved on to Constantinople with his companions around 1034. In Constantinople, he rose quickly to become the commander of the Byzantine Varangian Guard, seeing action on the Mediterranean Sea, in Asia Minor, Sicily, possibly in the Holy Land, Bulgaria and in Constantinople itself, where he became involved in the imperial dynastic disputes. Harald amassed considerable wealth during his time in the Byzantine Empire, which he shipped to Yaroslav in Kievan Rus' for safekeeping. In 1042, he left the Byzantine Empire, returning to Kievan Rus' in order to prepare to reclaim the Norwegian throne. Possibly to Harald's knowledge, in his absence the Norwegian throne had been restored from the Danes to Olaf's illegitimate son Magnus the Good. (Full article...)
Cyril (Greek: Κύριλλος, romanized: Kýrillos; born Constantine, 826–869) and Methodius (Μεθόδιος, Methódios; born Michael, 815–885) were brothers, ByzantineChristian theologians and missionaries. For their work evangelizing the Slavs, they are known as the "Apostles to the Slavs".
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...)
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.
