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".
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 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.

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 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...)

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...)
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...)
A group of Andalusian exiles led by Abu Hafs Umar al-Iqritishi conquered Crete in either 824 or 827/828, and established an independent Islamic state. The Byzantines launched a campaign that took most of the island back in 842-43 under Theoktistos, but the reconquest was not completed and would soon be reversed. Later attempts by the Byzantine Empire to recover the island failed, and for the approximately 135 years of its existence, the emirate was one of the major foes of Byzantium. Crete commanded the sea lanes of the Eastern Mediterranean and functioned as a forward base and haven for Muslim corsair fleets that ravaged the Byzantine-controlled shores of the Aegean Sea. The emirate's internal history is less well known, but all accounts point to considerable prosperity deriving not only from piracy but also from extensive trade and agriculture. The emirate was brought to an end by Nikephoros Phokas, who successfully campaigned against it in 960–961, re-annexing the island to the Byzantine Empire. (Full article...)

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

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, a former church, and 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 Eastern Orthodox church from 360 AD to 1204, when it was converted to a Catholic church following the Fourth Crusade. It was reclaimed in 1261 and remained Eastern Orthodox until the Ottoman conquest 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 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...)
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...)
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.

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

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

The 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.

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

The work as planned had three parts: the Code (Codex) is a compilation, by selection and extraction, of imperial enactments to date; the Digest or Pandects (the Latin title contains both Digesta and Pandectae) is an encyclopedia composed of mostly brief extracts from the writings of Roman jurists; and the Institutes (Institutiones) is a student textbook, mainly introducing the Code, although it has important conceptual elements that are less developed in the Code or the Digest. All three parts, even the textbook, were given force of law. They were intended to be, together, the sole source of law; reference to any other source, including the original texts from which the Code and the Digest had been taken, was forbidden. Nonetheless, Justinian found himself having to enact further laws; today these are counted as a fourth part of the Corpus, the Novellae Constitutiones (Novels, literally New Laws). (Full article...)
The 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 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.

Coin depicting John II Megas Komnenos
John II Megas Komnenos (Greek: Ἰωάννης Μέγας Κομνηνός, Iōannēs Megas Komnēnos) (c. 1262 – 16 August 1297) was a turkEmperor of Trebizond from June 1280 to his death in 1297. He was the youngest son of Emperor Manuel I and his third wife, Irene Syrikaina, a Trapezuntine noblewoman. John succeeded to the throne after his full-brother George was betrayed by his archons on the mountain of Taurezion. It was during his reign that the style of the rulers of Trebizond changed; until then, they claimed the traditional title of the Byzantine emperors, "Emperor and Autocrat of the Romans", but from John II on they changed it to "Emperor and Autocrat of all the East, the Iberians, and the Transmarine Provinces", although Iberia had been lost in the reign of Andronikos I Gidos.
John is the first ruler of Trebizond for whom we know more than a few incidents and hints; there is enough information to compose a connected narrative of the first part of his reign. The chronicle of Michael Panaretos, which is often terse and even cryptic, is relatively full for John's reign, and external sources add further details to Panaretos' account. Emperor John II faced many challenges to his rule, which partly explains his marriage to the daughter of the Byzantine emperor Michael VIII Palaiologos. (Full article...)

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.

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. After two foiled plots, Theodora was exiled to an island monastery in the Sea of Marmara in 1031. A decade later, the people of Constantinople rose against Michael IV's nephew and successor, Michael V, and insisted that Theodora return to rule alongside Zoë. (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.
Anna Komnene (Greek: Ἄννα Κομνηνή, romanized: Ánna Komnēnḗ; 1 December 1083 – 1153), commonly Latinized as Anna Comnena, was a Byzantine Greek princess and historian. She is the author of the Alexiad, an account of the reign of her father, Byzantine emperor Alexios I Komnenos. Her work constitutes the most important primary source of Byzantine history of the late 11th and early 12th centuries, as well as of the early Crusades. Although she is best known as the author of the Alexiad, Anna played an important part in the politics of the time and attempted to depose her brother, John II Komnenos, as emperor in favour of her husband, Nikephoros.
At birth, Anna was betrothed to Constantine Doukas, and she grew up in his mother's household. She was well-educated in "Greek literature and history, philosophy, theology, mathematics, and medicine." Anna and Constantine were next in the line to throne until Anna's younger brother, John II Komnenos, became the heir in 1092. Constantine died around 1094, and Anna married Nikephoros Bryennios in 1097. The two had several children before Nikephoros' death around 1136. (Full article...)
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".

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...)

Gold solidus struck during the revolt of the Heraclii, depicting Heraclius the Elder and his son, the future Emperor Heraclius, wearing consular robes.
Heraclius the Elder (Greek: Ἡράκλειος, Herákleios; died 610) was a Byzantine general and the father of Byzantine emperor Heraclius (r. 610–641). Generally considered to be of Armenian origin, Heraclius the Elder distinguished himself in the war against the Sassanid Persians in the 580s. As a subordinate general (or hypostrategos), Heraclius served under the command of Philippicus during the Battle of Solachon and possibly served under Comentiolus during the Battle of Sisarbanon. Circa 595, Heraclius the Elder is mentioned as a magister militum per Armeniam sent by Emperor Maurice (r. 582–602) to quell an Armenian rebellion led by Samuel Vahewuni and Atat Khorkhoruni. Circa 600, he was appointed as the Exarch of Africa and in 608, he rebelled with his son against the usurper Phocas (r. 602–610). Using North Africa as a base, the younger Heraclius managed to overthrow Phocas, beginning the Heraclian dynasty, which would rule Byzantium for a century. Heraclius the Elder died soon after receiving news of his son's accession to the Byzantine throne. (Full article...)
Constantine V (Greek: Κωνσταντῖνος, translit.Kōnstantīnos; Latin: Constantinus; July 718 – 14 September 775) was Byzantine emperor from 741 to 775. His reign saw a consolidation of Byzantine security from external threats. As an able military leader, Constantine took advantage of civil war in the Muslim world to make limited offensives on the Arab frontier. With this eastern frontier secure, he undertook repeated campaigns against the Bulgars in the Balkans. His military activity, and policy of settling Christian populations from the Arab frontier in Thrace, made Byzantium's hold on its Balkan territories more secure.
Religious strife and controversy was a prominent feature of his reign. His fervent support of Iconoclasm and opposition to monasticism led to his vilification by later Byzantine historians and writers, who denigrated him with the nicknames "the Dung-Named" (Greek: Κοπρώνυμος, translit.Koprónimos; Latin: Copronymus), because he allegedly defaecated during his baptism, similarly "Anointed with Urine" (Greek: Οὐραλύφιος, translit.Ouralýphios; Latin: Uralyphius), and "the Equestrian" (Greek: Καβαλλινος, translit.Kaballinos; Latin: Caballinus), referencing the excrement of horses.

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...)
Anastasius I Dicorus (Greek: Ἀναστάσιος, translit.Anastásios; c. 431 – 9 July 518) was Eastern Roman emperor from 491 to 518. A career civil servant, he came to the throne at the age of 61 after being chosen by the wife of his predecessor, Zeno. His reign was characterised by reforms and improvements in the empire's government, finances, economy and bureaucracy. He is noted for leaving the empire with a stable government, reinvigorated monetary economy and a sizeable budget surplus, which allowed the empire to pursue more ambitious policies under his successors, most notably Justinian I. Since many of Anastasius' reforms proved long-lasting, his influence over the empire endured for many centuries.
Anastasius was a Monophysite Christian and his personal religious tendencies caused tensions throughout his reign in the empire that was becoming increasingly divided along religious lines. He is venerated as a saint by the Syriac Orthodox Church on 29 July. (Full article...)
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...)

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...)

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...)

Alexios Doukas Philanthropenos (Greek: Ἀλέξιος Δούκας Φιλανθρωπηνός) was a Byzantine nobleman and notable general. A relative of the ruling Palaiologos dynasty, he was appointed commander-in-chief in Asia Minor in 1293 and for a time re-established the Byzantine position there, scoring some of the last Byzantine successes against the Turkish beyliks. In 1295 he rose up in revolt against Andronikos II Palaiologos, but was betrayed and blinded. Nothing is known of him until 1323, when he was pardoned by Andronikos II and sent again against the Turks, relieving a siege of Philadelphia, allegedly by his mere appearance. He was then named briefly governor of Lesbos in 1328, and again in 1336, when he recovered the island's capital from Latin occupation. He ruled the island thereafter, probably until his death in the 1340s. (Full article...)
Kassia, Cassia or Kassiani (Greek: Κασσιανή, romanized: Kassianí, pronounced[kasia'ni]; c. 810 – before 865) was a Byzantine-Greek composer, hymnographer and poet. She holds a unique place in Byzantine music as the only known woman whose music appears in the Byzantine liturgy. Approximately fifty of her hymns are extant, most of which are stichera, though at least 26 have uncertain attribution. The authenticity issues are due to many hymns being anonymous, and others ascribed to different authors in different manuscripts. She was an abbess of a convent in the west of Constantinople.
Additionally, many epigrams and gnomic verses are attributed to her, at least 261. Kassia is notable as one of at least two women in the middle Byzantine period known to have written in their own names, the other being Anna Comnena. Like her predecessors Romanos the Melodist and Andrew of Crete, the earliest surviving manuscripts of her works are dated centuries after her lifetime. (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.

Gold tetarteron of Isaac I Komnenos, showing the Emperor wielding a globus cruciger and holding a sheathed sword
The son of the general Manuel Erotikos Komnenos, he was orphaned at an early age, and was raised under the care of Emperor Basil II. He made his name as a successful military commander, serving as commander-in-chief of the eastern armies between c. 1042 and 1054. In 1057 he became the head of a conspiracy of the dissatisfied eastern generals against the newly crowned Michael VI Bringas. Proclaimed emperor by his followers on 8 June 1057, he rallied sufficient military forces to defeat the loyalist army at the Battle of Hades. While Isaac was willing to accept a compromise solution by being appointed Michael's heir, a powerful faction in Constantinople, led by the ambitious Patriarch of Constantinople, Michael Keroularios, pressured Michael to abdicate. After Michael abdicated on 30 August 1057, Isaac was crowned emperor in the Hagia Sophia on 1 September. (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...)

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

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...)
