The foundation of Constantinople in 330 AD marks the conventional start of the Eastern Roman Empire, which fell to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors who never attained the status of sole or senior ruler, as well as of the various usurpers or rebels who claimed the imperial title.

The following list starts with Constantine the Great, the first Christian emperor, who rebuilt the city of Byzantium as an imperial capital, Constantinople, and who was regarded by the later emperors as the model ruler. Modern historians distinguish this later phase of the Roman Empire as Byzantine due to the imperial seat moving from Rome to Byzantium, the Empire's integration of Christianity, and the predominance of Greek instead of Latin.

The Byzantine Empire was the direct legal continuation of the eastern half of the Roman Empire following the division of the Roman Empire in 395. Emperors listed below up to Theodosius I in 395 were sole or joint rulers of the entire Roman Empire. The Western Roman Empire continued until 476. Byzantine emperors considered themselves to be Roman emperors in direct succession from Augustus;[2] the term "Byzantine" became convention in Western historiography in the 19th century. The use of the title "Roman Emperor" by those ruling from Constantinople was not contested until after the papal coronation of the Frankish Charlemagne as Holy Roman emperor (25 December 800).

The title of all emperors preceding Heraclius was officially "Augustus"[b], although other titles such as Dominus were also used. Their names were preceded by Imperator Caesar and followed by Augustus. Following Heraclius, the title commonly became the Greek Basileus (Gr. Βασιλεύς), which had formerly meant sovereign, though Augustus continued to be used in a reduced capacity. Following the establishment of the rival Holy Roman Empire in Western Europe, the title "Autokrator" (Gr. Αὐτοκράτωρ) was increasingly used. In later centuries, the emperor could be referred to by Western Christians as the "emperor of the Greeks". Towards the end of the Empire, the standard imperial formula of the Byzantine ruler was "[Emperor's name] in Christ, Emperor and Autocrat of the Romans" (cf. Ῥωμαῖοι and Rûm).[3]

Dynasties were a common tradition and structure for rulers and government systems in the Medieval period. The principle or formal requirement for hereditary succession was not a part of the Empire's governance;[4] hereditary succession was a custom and tradition, carried on as habit and benefited from some sense of legitimacy, but not as a "rule" or inviolable requirement for office at the time.[1]

| Constantine I
"the Great"
Flavius Valerius Constantinus | 25 July 306 – 22 May 337
(30 years, 9 months and 27 days)
West; then whole | Born at Naissus c. 272 as the son of the Augustus Constantius and Helena. Proclaimed Augustus of the western empire upon the death of his father on 25 July 306, he became sole ruler of the western empire after the Battle of the Milvian Bridge in 312. In 324, he defeated the eastern Augustus Licinius and re-united the empire under his rule, reigning as sole emperor until his death. Constantine completed the administrative and military reforms begun under Diocletian, who had begun ushering in the Dominate period. Actively interested in Christianity, he played a crucial role in its development and the Christianization of the Roman world, through his convocation of the First Ecumenical Council at Nicaea. He is said to have received baptism on his deathbed. He also reformed coinage through the introduction of the gold solidus, and initiated a large-scale building program, crowned by the re-foundation the city of Byzantium as "New Rome", popularly known as Constantinople. He was regarded as the model of all subsequent Byzantine emperors.[9] His reign was marked by greater imperial control over the Eastern Church and the construction of new churches, especially at the holy places sacred to Christianity.[10] To this day, Constantine is venerated as a saint by the eastern Orthodox church.[11]
| Constantius II
Flavius Julius Constantius | 9 September 337 – 3 November 361
(24 years, 1 month and 25 days)
East; then whole | Born on 7 August 317, as the second surviving son of Constantine I, he inherited the eastern third of Roman Empire upon his father's death, sole Roman Emperor from 353, after the overthrow of the western usurper Magnentius; after two years on the run, the latter committed suicide.[12] Constantius' reign saw military activity on all frontiers, and dissension between Arianism, favoured by the emperor, and the supporters of the Nicene Creed. In his reign, Constantinople was accorded equal status to Rome, and the original Hagia Sophia was built. Constantius appointed Constantius Gallus and Julian as Caesares, and died on his way to confront Julian, who had risen up against him.[13]
| Julian "the Apostate"
Flavius Claudius Julianus | 3 November 361 – 26 June 363
(1 year, 7 months and 23 days) | Born in May 332 at Constantinople (the first emperor born there),[14] Julian was the grandson of Constantius Chlorus and cousin of Constantius II. Proclaimed by his army in Gaul, he became the legitimate Emperor upon the death of Constantius. Julian has been described as the last pagan emperor of the Roman Empire and was generally opposed to Christianity.[15] He was killed on campaign against Sassanid Persia, despite his initial success in surrounding the ancient city of Ctesiphon. For his adherence to the old Roman gods and rejection of the Christian faith, he became known as Julian the Apostate.[16]
| Jovian
Jovianus[d] | 27 June 363 – 17 February 364
(7 months and 21 days) | Born in c. 332, Jovian hailed from a military family and was captain of the guards (protector domesticus) under both Constantius II and Julian.[18] He was elected by the army upon Julian's death. After assuming power, Jovian withdrew Roman forces from Persia and made an unpopular peace with them, which lasted until the early sixth-century.[19] Following an autumn spent in Antioch, he died of natural causes in central Anatolia and was buried in Constantinople.[19]

| Valentinian I "the Great"
Valentinianus | 25/26 February 364 – 17 November 375
(11 years, 8 months and 23 days)
Whole; then West | Born in 321. An officer under Julian and Jovian, he was elected by the army upon Jovian's death. He soon appointed his younger brother Valens as Emperor of the East, while he himself ruled in the West. Died of cerebral haemorrhage in 375.
| Valens | 28 March 364 – 9 August 378
(14 years, 4 months and 12 days; East) | Born in 328, Valens was not especially fit for the imperial office if Ammianus can be believed, but he was appointed Emperor of the East in 364 by his elder brother Valentinian I, who wanted a malleable colleague in the other half of the Empire.[21][f] Following Valentinians's death in 375, his son Gratian succeeded him. Meanwhile, Valens faced the challenge of the invading Huns, whose ferocity pushed the Gothic tribes to seek refuge within the Empire; Valens allowed them to settle on the condition that they become allies to the Empire.[23] When the Goths were mistreated at Roman hands and rebelled, Valens proceeded to face them without awaiting assistance from Gratian's armies and was killed at the Battle of Adrianople.[24]
| Procopius (#)  | 28 September 365 – 27 May 366
(7 months and 29 days; East) | Maternal cousin of Julian; revolted against Valens and captured Constantinople, where the people proclaimed him emperor. Deposed, captured and executed by Valens.[25]

## Theodosian dynasty (379–457)

|
|

| Theodosius I
"the Great"  | 19 January 379 – 17 January 395
(15 years, 11 months and 29 days)
East; then whole | Born on 11 January 347 in Spain, Theodosius was an aristocrat and military leader, and later brother-in-law of Gratian, who appointed him as emperor of the East in 379 and gave him charge of Macedonia and Dacia.[26] During his reign, Theodosius made Nicene Christianity the official religion of the state.[27] He reunited the whole Empire after defeating Eugenius at the Battle of the Frigidus, in September 394.[28] Theodosius died of a fever at Milan in 395 and his two sons, Honorius and Arcadius, became the emperors of the West and East, splitting power between them.[29]
| Arcadius | 17 January 395 – 1 May 408
(13 years, 3 months and 14 days; East) | Born in 377/378, Arcadius was the eldest son of Theodosius I and upon the latter's death in 395, the Roman Empire was permanently divided between the Eastern Roman Empire—later referred to as the Byzantine Empire—and the Western Roman Empire with Arcadius becoming Byzantine emperor in the East while his younger brother Honorius became emperor in the West; both were manipulated by court officials and did not possess their father's leadership abilities.[30] After contracting an illness, Arcadius died in 408.[31]

| Theodosius II
"the Calligrapher"  | 1 May 408 – 28 July 450
(42 years, 2 months and 27 days; East) | Born on 10 April 401, he was the only son of Emperor Arcadius and Empress Aelia Eudoxia. Theodosius II succeeded the throne in 408 upon the death of his father. Because he was a minor, the praetorian prefect Anthemius was essentially regent from 408 to 414, but Theodosius II's elder sister Aelia Pulcheria played a critical role as regent and co-ruler during his early years. Pulcheria exerted considerable influence, shaping court policies and fostering Christian orthodoxy.[32] Theodosius II was known for his mild and scholarly temperament. He had a keen interest in theology, astronomy, and calligraphy, and was reportedly well-educated, thanks to the influence of his sister Pulcheria. His long reign was marked by significant legal, administrative, and theological developments. One of the most enduring legacies of Theodosius II's reign was the construction of the Theodosian Walls of Constantinople.[33] These massive fortifications protected the city for over a millennium and are regarded as one of the greatest defensive structures of antiquity.[34] Theodosius II strongly supported Nicene Christianity and convened the Council of Ephesus in 431 CE, which declared the Virgin Mary as Theotokos ("God-bearer") and condemned the theology of Nestorianism.[35] He also commissioned the Theodosian Code, a comprehensive compilation of Roman laws published in 438; this codex organized and systematized the legal framework of the empire and influenced later European legal traditions.[36] During his reign, he faced constant threats from the Huns of Attila and negotiated treaties with them, paying substantial tributes to prevent invasions.[37] He married Aelia Eudocia Augusta, a learned woman of Greek descent, who, like the emperor's sister Pulcheria, became an influential figure in the court. Their marriage produced one daughter, Licinia Eudoxia, who later married Valentinian III, the Western Roman Emperor.[38] Theodosius II died in 450 CE from injuries sustained after falling off his horse while hunting.[39] His death marked the end of a relatively peaceful and prosperous reign, though it left unresolved issues such as rising threats from external enemies and religious divisions.
| Marcian
Marcianus | 25 August 450 – 27 January 457
(6 years, 5 months and 2 days; East) | Born in 396. A soldier and politician, he became emperor after being wed by the Augusta Pulcheria, sister of Theodosius II, following the latter's death. Died of gangrene.

## Leonid dynasty (457–518)

| Leo I "the Thracian"  | 7 February 457 – 18 January 474
(16 years, 11 months and 11 days) | Born in Dacia c. 400, and of Bessian origin, Leo became a low-ranking officer and served as an attendant of the Gothic magister militum, Aspar, who chose him as emperor on Marcian's death. He was the first emperor to be crowned by the Patriarch of Constantinople, and the first one to legislate in Greek.[40] His reign was marked by the pacification of the Danube and peace with Persia, which allowed him to intervene in the affairs of the West, supporting candidates for the throne and dispatching an expedition to recover Carthage from the Vandals in 468. Initially a puppet of Aspar, Leo began promoting the Isaurians as a counterweight to Aspar's Goths, marrying his daughter Ariadne to the Isaurian leader Tarasicodissa (Zeno). With their support, in 471 Aspar was murdered and Gothic power over the army was broken.[41]
| Leo II "the Younger"  | 18 January – November 474
(10 months) | Born 468, he was the grandson of Leo I by Leo's daughter Ariadne and her Isaurian husband, Zeno. He was raised to Augustus on 17 November 473. Leo ascended the throne after the death of his grandfather on 18 January 474. He crowned his father as co-emperor and effective regent on 29 January, dying shortly after.
| Zeno | 29 January 474 – 9 January 475
(11 months and 11 days) | Born c. 425 in Isauria, originally named Tarasicodissa. As the leader of Leo I's Isaurian soldiers, he rose to comes domesticorum, married the emperor's daughter Ariadne and took the name Zeno, and played a crucial role in the elimination of Aspar and his Goths. He was named co-emperor by his son on 29 January 474 and became sole ruler upon the latter's death, but had to flee to his native country before Basiliscus in 475, regaining control of the capital in 476. Zeno concluded peace with the Vandals, saw off challenges against him by Illus and Verina, and secured peace in the Balkans by enticing the Ostrogoths under Theodoric the Great to migrate to Italy where the Gothic king ruled.[42] Convincing Theodoric to move his Goths westward into Italy allowed Zeno to reduce what had been a drain to imperial resources, since these Germanic warriors had been exacting payments from the Empire throughout the 470s and 480s and menacing Eastern territories.[43] As a consequence, Zeno's reign also saw the end of the western line of emperors. His pro-Miaphysite stance made him unpopular and his promulgation of the Henotikon resulted in the Acacian Schism with the papacy.[44]
| Basiliscus | 9 January 475 – August 476
(1 year and 7 months)

* * *

with Marcus (475–476)[g] | General and brother-in-law of Leo I, seized power from Zeno and crowned himself emperor on 12 January. Zeno was restored soon after. Died in 476/477
| Zeno
(second reign) | August 476 – 9 April 491
(14 years and 8 months) | Retook the throne with the help of general Illus. Saw the end of the Western Roman Empire. Died of dysentery or epilepsy[47]
| Anastasius I "Dicorus"  | 11 April 491 – 9 July 518
(27 years, 2 months and 28 days) | Born c. 430 at Dyrrhachium, Anastasius was a palace official (silentiarius) when he was chosen as the husband and ultimately Emperor by Empress-dowager Ariadne. He was nicknamed "Dikoros" (Latin: Dicorus), because of his heterochromia. Apparently, there was some insistence from the citizenry of Constantinople that Zeno's successor should be an "Orthodox" Christian, which caused Ariadne to turn to Anastasius in the first place.[48] Anastasius reformed the tax system and the Byzantine coinage and proved a frugal ruler, so that by the end of his reign he left a substantial surplus. His Miaphysitism led to widespread opposition, most notably the Revolt of Vitalian and the Acacian Schism.[49] His reign was also marked by the first Bulgar raids into the Balkans and by a war with Persia over the foundation of Dara. He died childless.[50] Shortly before his death, he tried to devise a means for one of his three nephews to succeed him by placing a note that read Regnum under their beds, but when none of them chose that bed, he decided instead to name the first person he saw the following morning. Keeping true to his word, when Justin—commander of the imperial guards—entered his presence first that morning, he was pronounced as Anastasius's successor.[51]

## Justinian dynasty (518–602)

Petrus Sabbatius Justinianus | 1 April 527 – 14 November 565
(38 years, 7 months and 13 days) | Born in 482/483 at Tauresium (Taor) Macedonia, Justinian was the nephew of Justin I and was made consul in 521; he was elevated to co-emperor on 1 April 527, when Justin fell ill.[52] He succeeded Justin I as emperor upon the former's death. Through his mighty commanding general Belisarius, Justinian was able to regain North Africa, as well as much of Italy and Spain; these were territories that had been seized and occupied previously by various Germanic tribes (Vandals and Goths) at the former Western Roman Empire's expense. He carried out a massive building program throughout the Empire, including construction of the famous Hagia Sophia at Constantinople.[53] Justinian was also responsible for the corpus juris civilis, or the "body of civil law", which is the foundation of law for many modern European nations.[54]
| Justin II
Justinus | 14 November 565 – 5 October 578
(12 years, 10 months and 21 days) | Born c. 520. Nephew of Justinian I, he seized the throne on the death of Justinian I with support of army and Senate. Became insane, hence in 573–574 under the regency of his wife Sophia, and in 574–578 under the regency of Tiberius Constantine.

* * *

with Theodosius (590–602)[g] | Born in 539 at Arabissus, Cappadocia. Maurice became an official and later a general of the Byzantine army in the East under Tiberius II, achieving notable successes against the Sassanian Empire during the Byzantine–Sassanian War of 572–591.[55] He married the daughter of Tiberius II and was proclaimed emperor on 13 August 582 after Tiberius II's death.[56] Maurice fought wars against the Sassanian kingdom on the eastern front of his empire, the Avars and Slavs for control over the Balkans, and reinforced Byzantine holdings in Ravenna and Carthage.[57] He is best remembered for his contributions to Byzantine military theory, notably his treatise Strategikon, a manual on warfare.[58] Maurice named his son Theodosius as co-emperor in 590. Deposed by a centurion named Phocas, he was captured and executed on 27 November 602 along with his family at Chalcedon.[59]
| Phocas
Focas | 23 November 602 – 5 October 610
(7 years, 10 months and 12 days) | Subaltern in the Balkan army, he led a rebellion that deposed Maurice. Increasingly unpopular and tyrannical, he was deposed and executed by Heraclius.

## Heraclian dynasty (610–695)

Brought the Byzantine-Sassanid War of 602–628 to successful conclusion but was unable to stop the Muslim conquest of Syria. Heraclius' officials worked to replace Latin with Greek as the official language of administration in the East.[62] By this time Latin had long fallen out of everyday use in the Eastern part of the Empire and Heraclius's adopting of the title basileus (king or emperor) "marked a shift from Rome towards a Greek and Eastern Christian culture."[63]
| Heraclius Constantine
(Constantine III)[i]
Heraclius Constantinus
Ἡράκλειος Κωνσταντῖνος | 11 February – 25 May 641
(3 months and 14 days) | Born on 3 May 612 as the eldest son of Heraclius by his first wife Fabia Eudokia. Named co-emperor on 22 January 613, he succeeded to throne with his younger brother Heraklonas following the death of Heraclius. Died of tuberculosis, allegedly poisoned by Empress-dowager Martina.

| Constans II "the Bearded"
Constantinus, Κωνσταντῖνος | September 641 – 15 July 668
(26 years and 10 months) | Born on 7 November 630, Constans II was the son of Constantine III. Raised to co-emperor in summer 641 after his father's death due to army pressure, he became sole emperor after the forced abdication of his uncle Heracleonas and his exile.[66] Baptized Heraclius, he reigned as Constantin but was given the nickname "Constans". He faced a number of Arab incursions, almost losing his life while commanding the Byzantine fleet. Constans had some military success against the Slavs in the Balkans.[67] Around 662, he moved his seat and court to Syracuse, intending to liberate Italy from the Lombards. His presence was unwelcome in Italy and there was "fierce opposition" to Constans II's abandonment of Constantinople. He was assassinated by a chamberlain in 668.[68]
| Constantine IV "the Younger"
Constantinus, Κωνσταντῖνος | September 668 – 10 July (?) 685
(16 years and 10 months)

with Heraclius and Tiberius, sons of Constans II (659–681)[g] | Born in 652, co-emperor since 13 April 654, he succeeded following the murder of his father Constans II. Erroneously called "Constantine the Bearded" by historians through confusion with his father. He called the Third Council of Constantinople which condemned the heresy of Monothelitism, repelled the First Arab Siege of Constantinople, and died of dysentery.
| Justinian II "Rhinotmetus"
Justinianus, Ἰουστινιανός | July 685 – 695
(10 years) | Born in 669, son of Constantine IV, he was named co-emperor in 681 and became sole emperor upon Constantine IV's death. Deposed by military revolt in 695, mutilated (hence his surname) and exiled to Cherson, whence he recovered his throne in 705.

|
|

| Basil I "the Macedonian"
Βασίλειος | 24 September 867 – 29 August 886
(18 years, 11 months and 5 days)

* * *

with Constantine (868–879)[g] | Born in the Theme of Macedonia c. 811, he rose in prominence through palace service, becoming a favourite of Michael III, who crowned him co-emperor on 26 May 866. He overthrew Michael and established the Macedonian dynasty. He led successful wars in the East against the Arabs and the Paulicians, and recovered southern Italy for the Empire.
| Leo VI "the Wise"
Λέων | 29 August 886 – 11 May 912
(25 years, 8 months and 12 days) | Born on 19 September 866, either the legitimate son of Basil I or the illegitimate son of Michael III. Co-emperor since 6 January 870. Leo was known for his erudition. His reign saw a height in Saracen (Muslim) naval raids, culminating in the Sack of Thessalonica, and was marked by unsuccessful wars against the Bulgarians under Simeon I.
| Alexander
Αλέξανδρος | 11 May 912 – 6 June 913
(1 year and 26 days) | Son of Basil I, Alexander was born in 870 and raised to co-emperor in 879. Sidelined by Leo VI, Alexander dismissed his brother's principal aides on his accession. Died of illness, possibly testicular cancer[69]
| Constantine VII
Porphyrogenitus
Κωνσταντῖνος | 6 June 913 – 9 November 959
(46 years, 5 months and 3 days) | Son of Leo VI, he was born on 17/18 May 905 and raised to co-emperor on 15 May 908. His early reign was dominated by successive regencies, first by his mother, Zoe Karbonopsina, and Patriarch Nicholas Mystikos, and from 919 by the admiral Romanos Lekapenos, who wedded his daughter to Constantine and was crowned senior emperor in 920. Constantine re-asserted his control by deposing Romanos's sons on 27 January 945. His reign was marked by struggles with Sayf al-Dawla in the East and an unsuccessful campaign against Crete, and pro-aristocratic policies that saw a partial reversal of Lekapenos' legislation against the dynatoi. He is notable for his promotion of the "Macedonian Renaissance", sponsoring encyclopaedic works and histories. He was a prolific writer himself, best remembered for the manuals on statecraft (De administrando imperio) and ceremonies (De ceremoniis) he compiled for his son.[70]
| Romanos I Lekapenos
Ῥωμανὸς | 17 December 920 – 20 December 944
(24 years and 3 days)

* * *

with Christopher (921–931), Stephen and Constantine Lekapenos (924–945)[g] | An admiral of lowly origin, Romanos rose to power as a protector of the young Constantine VII against the general Leo Phokas the Elder. He became emperor in 920. His reign was marked by the end of warfare with Bulgaria and the great conquests of John Kourkouas in the East.[71] Romanos promoted his sons Stephen and Constantine (alongside Christopher, who died soon after) as co-emperors over Constantine VII, but was himself overthrown by them and confined to an island as a monk. He died there on 15 June 948.[72]
| Romanos II
Ῥωμανὸς | 9 November 959 – 15 March 963
(3 years, 4 months and 6 days) | The only surviving son of Constantine VII, he was born on 15 March 938 and succeeded his father on the latter's death. He ruled until his own death, although the government was led mostly by the eunuch Joseph Bringas. His reign was marked by successful warfare in the East against Sayf al-Dawla and the recovery of Crete by general Nikephoros Phokas.
| Nikephoros II Phokas
Νικηφόρος | 16 August 963 – 11 December 969
(6 years, 3 months and 25 days) | The most successful general of his generation, Nikephoros II was born c. 912 to the powerful Phokas clan. After the death of Romanos II, he rose to the throne with the support of the army and people as regent for the young emperors Basil II and Constantine VIII, marrying the empress-dowager Theophano. Throughout his reign he led campaigns in the East, conquering much of Syria. He was murdered by his nephew and one-time associate John Tzimiskes.
| John I Tzimiskes
Ἰωάννης | 11 December 969 – 10 January 976
(6 years and 30 days) | Nephew of Nikephoros Phokas, Tzimiskes was born c. 925\. A successful general, he fell out with his uncle and led a conspiracy of disgruntled generals who murdered him. Tzimiskes succeeded Nikephoros as emperor and regent for the young sons of Romanos II. As ruler, Tzimiskes crushed the Rus' in Bulgaria and ended the Bulgarian tsardom before going on to campaign in the East, where he died.
| Basil II "the Bulgar-Slayer"
Βασίλειος | 10 January 976 – 15 December 1025
(49 years, 11 months and 5 days) | Eldest son of Romanos II, Basil II was born in 958 to Romanus II.[73] The first decade of his reign was marked by rivalry with the powerful Basil Lekapenos, an unsuccessful war against Bulgaria, and rebellions by generals in Asia Minor. Basil solidified his position through a marriage alliance of his sister Anna to Vladimir I of Kiev, which was accompanied by the conversion to Christian Orthodoxy of the grand Kievian Rus' prince and his people.[74] After over 20 years of war, Basil eventually succeeded in his conquest of Bulgaria, which was finally subdued in 1018, earning him the name "Bulgar-slayer".[75] His conquest of Bulgar was periodically interrupted by warfare in Syria against the Fatimid Caliphate. Basil expanded Byzantine control over most of Armenia and his reign is widely considered as the apogee of medieval Byzantium.[76]
| Constantine VIII
Κωνσταντῖνος | 15 December 1025 – 12 November 1028
(2 years, 10 months and 28 days) | The second son of Romanos II, Constantine was born in 960 and raised to co-emperor on 30 March 962. During the rule of Basil II, he spent his time in idle pleasure. During his short reign he was an indifferent ruler, easily influenced by his courtiers and suspicious of plots to depose him, especially among the military aristocracy, many of whom were blinded and exiled.[77]
| Romanos III Argyros
Ῥωμανὸς | 12 November 1028 – 11 April 1034
(5 years, 4 months and 30 days) | Born in 968, the elderly aristocrat Romanos—who had served in both the judiciary and civil service—was chosen by Constantine VIII on his deathbed, after being required to marry the emperor's daughter Zoe under the alternative threat of being blinded and sent to a monastery. Romanos III succeeded to the throne upon Constantine's death a few days later.[78] Deluded by grandeur, Romanos fashioned himself at one time as a philosopher king like Marcus Aurelius and later as a military genius like Trajan, resulting in military debacles. He initiated expensive church building projects. A subsequent affair between his wife Zoe and  his chief eunuch's brother Michael, led to the pair colluding in poisoning Romanos, before ultimately resolving to having the emperor strangled and drowned in his own bath.[79]
| Michael IV "the Paphlagonian"
Μιχαὴλ | 12 April 1034 – 10 December 1041
(7 years, 7 months and 28 days) | Born in 1010, he became a lover of Zoe even while Romanos III was alive, and succeeded him upon his death as her husband and emperor. Aided by his older brother, the eunuch John the Orphanotrophos, his reign was moderately successful against internal rebellions, but his attempt to recover Sicily failed. He died after a long illness.
| Michael V "Kalaphates"
Μιχαὴλ | 13 December 1041 – 21 April 1042
(4 months and 8 days) | Born in 1015, he was the nephew and adopted son of Michael IV. During his reign he tried to sideline Zoe, but a popular revolt forced him to restore her as empress on 19 April 1042, along with her sister Theodora. He was deposed the next day, castrated and tonsured, dying on 24 August 1042.
| Zoë Porphyrogenita
Ζωή | 21 April – 11 June 1042
(1 month and 21 days) | The daughter of Constantine VIII, she succeeded on her father's death, as the only surviving member of the Macedonian dynasty, along with her sister Theodora. Her three husbands, Romanos III (1028–1034), Michael IV (1034–1041) and Constantine IX (1042–1050) ruled alongside her.
| Theodora Porphyrogenita
Θεοδώρα | 21 April – 11 June 1042
(1 month and 21 days) | The younger sister of Zoe, born in 984, she was raised as co-ruler on 19 April 1042. After Zoe married her third husband, Constantine IX, in June 1042, Theodora was again sidelined. After Zoe died in 1050 and Constantine in 1055, Theodora assumed full governance of the Empire and reigned until her death. She nominated Michael VI as her successor.
| Constantine IX Monomachos
Κωνσταντῖνος Μονομάχος[k] | 11 June 1042 – 11 January 1055
(12 years and 7 months) | Born c. 1000 of noble origin, he had an undistinguished life but was exiled to Lesbos by Michael IV, returning when he was chosen as Zoe's third husband. Constantine supported the mercantile classes and favoured the company of intellectuals, thereby alienating the military aristocracy. A pleasure-loving ruler, he lived an extravagant life with his favourite mistresses and endowed a number of monasteries, chiefly the Nea Moni of Chios and the Mangana Monastery. His reign was marked by invasions by the Pechenegs in the Balkans and the Seljuk Turks in the East, the revolts of George Maniakes and Leo Tornikios, and the Great Schism between the patriarchates of Rome and Constantinople.[81]
| Theodora Porphyrogenita
Θεοδώρα
(second reign) | 11 January 1055 – 31 August 1056
(1 year, 7 months and 20 days) | Claimed the throne again after Constantine IX's death as the last living member of the Macedonian dynasty. Died of natural causes[82]
| Michael VI Bringas "Stratiotikos"
Μιχαήλ[k] | 22 August 1056 – 30 August 1057
(1 year and 8 days) | A court bureaucrat and stratiotikos logothetes (hence his first sobriquet). Proclaimed emperor by Theodora on her deathbed on 22 August 1056. Deposed by military revolt under Isaac Komnenos, he retired to a monastery where he died in 1059.
| Isaac I Komnenos
Ἰσαάκιος Κομνηνός | 1 September 1057 – 22 November 1059
(2 years, 2 months and 21 days) | Born c. 1005. A successful general, he rose in revolt leading the eastern armies and was declared emperor on 8 June 1057; he was recognized after the abdication of Michael. He resigned in 1059 and died c. 1061.

Co-emperor since 1059, he succeeded on his father's death.

Senior emperor in 1071–78, he named his son Constantine co-emperor alongside his brothers. He abdicated before the revolt of Nikephoros Botaneiates, retired to a monastery and died c. 1090.

## Laskaris dynasty (1205–1261)

[edit]

Main articles: Laskaris and Empire of Nicaea

Note: Roman rule in Constantinople was interrupted with the capture and sack of the city by the crusaders in 1204, which led to the establishment of the Frankokratia. Though the crusaders created a new line of Latin emperors in the city, modern historians recognize the line of emperors of the Laskaris dynasty, reigning in Nicaea, as the legitimate Roman emperors during the struggle for Constantinople because the Nicene Empire eventually retook the city.[89] For other lines of claimant emperors, see List of Trapezuntine emperors and List of Thessalonian emperors.

Proclaimed emperor after Constantine's death in 1205, Theodore was crowned only in Easter 1208. He managed to stop the Latin advance in Asia and to repel Seljuk attacks, establishing the Empire of Nicaea as the strongest of the Greek successor states.

with Anna (1351–1365, in Thessalonica) | While the only son of Andronikos III, John V was not crowned or declared heir at his father's death—partly due to being only 10-years old at the time—which contributed to the outbreak of a destructive civil war between his regents and his father's closest aide, John VI Kantakouzenos, who was instead crowned co-emperor.[96] The conflict ended in 1347 with Kantakouzenos recognized as senior emperor, but he was deposed by John V during another civil war.[97] After successful Turkish incursions and their seizure of Adrianople, John V appealed to the West for aid against the Ottomans, even going so far as to seek religious union and journeying to Rome to convert to Catholicism.[98] Despite his efforts otherwise, John V was forced to recognize Ottoman suzerainty in 1371.[99]
| John VI Kantakouzenos
Ἰωάννης Ἄγγελος Κομνηνὸς Παλαιολόγος Καντακουζηνός | 8 February 1347 – 10 December 1354
(7 years, 10 months and 2 days)

with Matthew Kantakouzenos (1353–1357)[g] | A maternal relative of the Palaiologoi, he was declared co-emperor on 26 October 1341, and was recognized as senior emperor for ten years after the end of the civil war on 8 February 1347. Deposed by John V in 1354, he became a monk, dying on 15 June 1383.
| Andronikos IV Palaiologos
Ἀνδρόνικος Κομνηνός Παλαιολόγος | 12 August 1376 – 1 July 1379
(2 years, 10 months and 19 days)
May 1381 – June 1385
(4 years, in Selymbria) | Son of John V and grandson of John VI, he was named co-emperor and heir in 1352, but imprisoned and partially blinded after a failed rebellion in May 1373. He rebelled again and successfully deposed his father in 1376. Deposed by John V in 1379, he fled to Galata in exile but was restored as co-emperor and heir in May 1381, ruling over Selymbria and the coast of Marmara. Rebelled again in June 1385 but died shortly thereafter[100]
| John VII Palaiologos
Ίωάννης Παλαιολόγος | 1385 – 1403
(18 years, in Selymbria)
14 April – 17 September 1390
(5 months and 3 days)
late 1403 – 22 September 1408
(5 years, in Thessalonica)

with Andronikos V Palaiologos (1403–1407, in Thessalonica)[g] | Son of Andronikos IV, he was born in 1370, and named co-emperor under his father in 1377–79. He usurped the throne from his grandfather John V for five months in 1390, but with Ottoman mediation he was reconciled with John V and his uncle, Manuel II. As regent, he held Constantinople against the Ottomans in 1399–1402, and was then given Thessalonica as an appanage, which he governed until his death on 22 September 1408.

| Manuel II Palaiologos
Μανουὴλ Παλαιολόγος | 1382 – 1387
(5 years, in Thessalonica)
16 February 1391 – 21 July 1425
(34 years, 4 months and 5 days) | Second son of John V, he was born on 27 June 1350. Raised to co-emperor in 1373, he became senior emperor on John V's death and ruled until his death. He journeyed to the West European courts seeking aid against the Turks, and was able to use the Ottoman defeat in the Battle of Ankara—thanks largely to the fact that Timur and the Tartars attacked the Turks when they were besieging Constantinople, which forced the Turks' retreat—to regain some territories and throw off his vassalage to them.[101] Manuel II died in 1425 and was succeeded by his son, John VIII.[102]

| John VIII Palaiologos
Ίωάννης Παλαιολόγος | 21 July 1425 – 31 October 1448
(23 years, 4 months and 10 days) | Eldest surviving son of Manuel II, he was born on 18 December 1392. Raised to co-emperor around 1416 and named full autokrator in 1425, he succeeded his father on his death. Seeking aid against the resurgent Ottomans, he ratified the Union of the Churches in 1439, a move to reunite the Orthodox and Catholic churches that proved very unpopular in Constantinople.[102]
| Constantine XI Palaiologos
Κωνσταντῖνος Δραγάσης Παλαιολόγος | 6 January 1449 – 29 May 1453
(4 years, 4 months and 23 days) | The fourth son of Manuel II and Serbian princess Helena Dragaš, he was born on 8 February 1405. As Despot of the Morea since 1428, he distinguished himself in campaigns that annexed the Principality of Achaea and brought the Duchy of Athens under temporary Byzantine suzerainty, but was unable to repel Turkish attacks under Turahan Bey. As the eldest surviving brother, he succeeded John VIII after the latter's death. Facing the designs of the new sultan, Mehmed II, on Constantinople, Constantine acknowledged the Union of the Churches and made repeated appeals for help to the West, but in vain. Refusing to surrender the city, he was killed in battle during the Fall of Constantinople on 29 May 1453.[103]

### Notes

[edit]

1. ^ Historian Donald Nicol writes, "Hereditary succession to the throne was a custom or a convenience in Byzantium, not an inviolable... principle. Emperors, particularly in the later period, would take pains to nominate their sons as co-emperors, for the rule of a dynasty made for stability and continuity. But in theory, the road to the throne was a carriere ouverte aux talents [career open to talents]..."[1]
2. ^ Sometimes the Greek-language equivalent "Sebastos" was used instead
3. ^ a b c d Unless otherwise noted to be some other ambiguity, the emperors marked to be of ambiguous legitimacy are those who fulfill one or more of the inclusion criteria above, but who are not universally regarded by scholars to count as legitimate. In most cases, such figures are those who held power only briefly, and/or who in times of more than one emperor held one of the capitals but never achieved the full recognition of the other emperor(s).[5][6][7][8]
4. ^ From the fourth century, emperors and other high-profile men of non-aristocratic birth often bore the name "Flavius", the family name of the Constantinian dynasty. Because it was often used as a status marker rather than personal name,[17] "Flavius" will generally be omitted in the following entries for simplicity.
5. ^ Distinction between nomen, praenomen and cognomen, the core elements of Roman naming conventions, began to fade away from the 3rd century onwards. Given that "new Romans" —that is, barbarians turned citizens— adopted the names of their masters, many citizens adopted the names Julius, Flavius (notable the Constantinians) and Marcus Aurelius (notable the 3rd century emperors), thus making them obsolete as surnames. As a result, most citizens of the Empire, even emperors, reverted back to single-names by the 5th century.[20]
6. ^ While some historians attribute the division of the Roman Empire into East and West after Theodosius the Great split the throne between his sons, the year 364 probably more accurately marks the point at which the Empire was actually divided.[22]
7. ^ a b c d e f g h i j k l m n o p q r s Although they constitutionally held the same supreme power as their senior counterpart, it is customary among scholars of the later empire to only regard those who actually ruled as emperors, omitting junior co-emperors who only exercised power nominally and never governed in their own name.[45][46]
8. ^ From 629 onwards, Heraclius issued administrative documents in Greek.[60] Latin continued to be used in communication with Western Europe until the end of the empire and coins continued to be struck with Latin inscriptions until the early eighth century.[61]
9. ^ Heraclius Constantine is often enumerated as 'Constantine III',[64] though this name is also often applied to the earlier western emperor and has also been used for Heraclius Constantine's son Constans II (who actually ruled under the name 'Constantine', 'Constans' being a nickname).[65]
10. ^ Latin ceased being used in coin inscriptions under Leo III.[61]
11. ^ a b Emperors began to officially use family names from Constantine IX Monomachos onwards. The sole exception after Constantine IX's reign is Michael VI, whose family name (Bringas) was far less distinguished than those of the other imperial families and thus does not appear in official use.[80]
12. ^ Some historians regard Eudokia as an empress regnant, while others consider her as a regent.
13. ^ Unattested in coinage; Leo is only called emperor in a singular letter, while his brother's status can only be deduced from the fact that he was born in the purple and that he also used the "imperial tokens".[84]
14. ^ Alexios III used the name Alexios Komnenos Angelos (Ἀλέξιος Κομνηνός Ἄγγελος) prior to his accession but reigned as Alexios Komnenos, dropping his own family name in order to stress his matrilineal descent from the Komnenos dynasty.[87]
