This is a list of the Emperors of the late Eastern Roman Empire, commonly known as the Byzantine Empire by modern historians. This list does not include numerous co-emperors who never attained sole or senior status as rulers.

This list begins with Constantine I the Great, the first Christian emperor reigning from Constantinople. Diocletian before him had ruled from Nicomedia and replaced the republican trappings of the office with a straightforward autocracy. All Byzantine Emperors regarded themselves as Roman Emperors.^[1]

The Emperor Heraclius (610-641) replaced Latin with Greek as the language of the army and began the administrative restructuring of the Empire into themata. Although Greek had long been the dominant language in the Eastern Roman Empire this change represented a formal rejection of the Latin language and many aspects of traditional Roman culture. Indeed after 800 AD the Pope and later the Franks would reject the Roman Imperial authority of Constantinople partially on this basis.

The title of all Emperors listed preceding Heraclius was officially Augustus, although various other titles such as Dominus were used as well. For official purposes, 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 generally "king", "sovereign" but now was used in place of Imperator. Kings were now titled by the neologism Regas (Gr. Ρήγας, from the Lat. "Rex") or by another generic term Archon (Gr. Άρχων, "ruler"). Autokrator (Gr. Αυτοκράτωρ) was also frequently used, along with a plethora of more hyperbolic titles including Kosmokrator (Gr. Κοσμοκράτωρ) ("Master of the World") and "Chronokrator" (Gr. Χρονοκράτωρ) ("Master of Time"). In the later centuries of the Empire, the emperor could be often referred to by Western Christians as the "Emperor of the Greeks," though they still considered themselves "Roman" Emperors.

[edit] Constantinian dynasty (306-363)

Name	Status	Birth	Emperor from	Emperor until	Notes
Constantine I "the Great" (Gaius Flavius Valerius Aurelius Constantinus)	son of the Augustus Constantius Chlorus	27 February c.280	25 July 306 Proclaimed "Augustus" upon the death of Constantius Chlorus	22 May 337	He declared himself "Augustus" in Eboracum, Britannia (Modern York), upon the death of Constantius Chlorus, and, after a period of prolonged civil war, became sole Emperor. He famously converted to Christianity, and began imperial favour of that religion. He founded Constantinople as a capital of the Empire. Divided the Empire between his three sons upon his death. Later canonised.
Constantius II (Flavius Iulius Constantius)	second son of Constantine I	7 August 317	22 May 337 Inherited Eastern third of Roman Empire upon his father's death	5 October 361 died of illness on campaign	By inheritance, he succeeded to the Eastern third; after his two brothers died, he became sole Emperor. He was responsible for the deaths of numerous family members in the wake of Constantine's death, and persecuted those remaining. His last cousin, Julian, rebelled against him in the last years of his life.
Julian "the Apostate" (Flavius Claudius Iulianus)	grandson of Constantius Chlorus, cousin of Constantius II	May 332	5 October 361 Proclaimed by his army in Gaul, became legitimate Emperor upon the death of Constantius	28 June 363 Mortally wounded in battle	The son of Constantine I's half brother, Julius Constantius, he was early orphaned by the death of his mother of childbed fever, and the murder of his father by the sons of Constantine I. Raised by Constantius II to the rank of Caesar, he ruled and defended Gaul very ably. He eventually rebelled, being proclaimed Augustus by his army, and seized control of Italy. He succeeded to the entire empire after Constantius' fortuitous death of illness. He died on campaign against the Sassanids. He is more famous, however, for his rejection of Christianity, and his doomed attempts to rejuvenate Paganism.

	Jovian ( Flavius Claudius Iovianus )	Guards' Captain amongst Julian's* Eastern forces*	c.332	28 June 363 Elected by the army upon Julian's* death*	17 February 364 Died on journey back to Constantinople		A non-entity, chosen by the army to succeed following Julian's intestate death. His only deeds worth mentioning were to secure the escape of the Roman army from Persia by signing a peace treaty; this treaty signed away Rome's furthest Eastern provinces to the Persians. He died before reaching his capital.

[edit] Valentinian-Theodosian dynasty (364-457)

Name	Status	Birth	Emperor from	Emperor until	Death	Notes
Valentinian I (Flavius Valentinianus)	Officer under Julian and Jovian	321	26 February 364 Elected by the army upon Jovian's* death*	17 November 375 Died of cerebral haemorrhage		Shortly after his accession, he chose his brother Valens to rule alongside him. The pair then partitioned the Empire between themselves. Valentinian thereafter ruled in the West only. During his reign, the Empire was repeatedly ravaged by barbarians. His anger at the invasion of the Quadi caused his fatal haemorrhage.
Valens ( Flavius Iulius Valens )	Minor soldier of the Roman army, brother of Valentinian I	328	28 March 364 Appointed by his brother	9 August 378 Killed at the Battle of Adrianople		Called "The Last True Roman", he was chosen to rule the East by his brother, Valentinian I. His reign was ineffective, and at one point he came close to abdication and suicide following the proclamation of an imperial pretender, Procopius. He was killed in the disastrous Battle of Adrianople, in which most of his armies were destroyed by Gothic invaders.
Gratian ( Flavius Gratianus )	Son of Valentinian I, nephew of Valens	18 April/23 May 359	9 August 378 Inherited rule of the East upon the death of Valens	19 January 379 Appointed Theodosius I* as Emperor of the East*	25 August 383 Assassinated during the rebellion of Magnus Maximus	He inherited the rule of the East upon Valens' death. He appointed one of his generals, Theodosius, as Emperor in the East in the following year. He was also Emperor in the West (with Valentinian II) 375-383
Theodosius I ( Flavius Theodosius )	Aristocrat and military leader, brother-in-law of Gratian	11 January 347	19 January 379 Appointed by Gratian	17 January 395 old age		He was appointed Emperor in the East by Gratian, who needed a loyal ally to deal with the effects of Adrianople. He restored the Eastern armies by taking many barbarian mercenaries into Roman service. After the deaths of Gratian and Valentinian II, he took control of the Western half of the Empire. He was the last Emperor to de facto rule the entire Empire. Made Christianity the official religion of the Empire.
Arcadius ( Flavius Arcadius )	Son of Theodosius I	377/378	17 January 395 Upon the death of Theodosius I	1 May 408		A weak Emperor, dominated by his wife Aelia Eudoxia and ministers. Brother of the Western Emperor Honorius
Theodosius II ( Flavius Theodosius )	Son of Arcadius	10 April 401	1 May 408 Upon the death of Arcadius	28 July 450 Riding accident		He was heavily influenced by his sister, Pulcheria, who declared herself "Augusta" in 414. During his reign, her Christian views led to persecution of non-Christians in the Empire. However, the period also saw the construction of Constantinople's near-impregnable Theodosian Walls, and the publication of the Codex Theodosianus. He died in 450, leaving his sister as his heir.
Pulcheria ( Aelia Pulcheria )	Daughter of Arcadius, sister of Theodosius II	19 January 399	28 July 450 Upon the death of Theodosius II	July 453		After the death of her father, Arcadius, she became politically prominent. She was responsible for appointing the barbarian Aspar as Eastern Roman "Master of Soldiers", a position he would use to his own ends. Strongly Christian, she encouraged her brother to rule according to Christian values. She became a nun after being forced from the court in 441, but returned after her brother's death. She then married Marcian, and the pair ruled together until 453. She was later canonised by the Eastern Orthodox Church
Marcian ( Flavius Marcianus )	Soldier, politician, husband of Pulcheria	396	450 Upon his marriage to Pulcheria	January 457 Gangrene contracted on a journey		He was elevated to the imperial throne by his marriage to Pulcheria. He was supported by Aspar. Under his rule, the Eastern Empire recovered from the political and military vicissitudes of the past ¾ of a century, and faced down Attila the Hun. The West, however, he left to fend for itself. He was canonised after his death by the Eastern Orthodox Church

[edit] Leonid dynasty (457-518)

Name	Status	Birth	Emperor from	Emperor until	Death	Notes
Leo I "the Thracian" (Flavius Valerius Leo )	Soldier	401	7 February 457 Chosen by Aspar, commander-in-chief of the army	18 January 474 Died of dysentery		He was chosen by Aspar, who attempted to rule through him; Leo resisted and broke Aspar's power. In order to do this, he was forced to ally with the Isaurians, whose leader Tarasicodissa married Leo's daughter Ariadne and took the Roman name "Zeno". He raised Theodoric the Great in his court. He was the first Emperor to be crowned by the Patriarch of Constantinople.
Leo II ( Flavius Leo )	Grandson of Leo I	467	18 January 474 Succeeded his grandfather Leo I	17 November 474 Died of an unknown disease, possibly poisoned		He was the son of Ariadne (daughter of Leo I) by Zeno. He inherited the throne upon his grandfather's death. It was rumoured that his mother had poisoned him to allow Zeno to take the throne.
Zeno ( Flavius Zeno ) (Born Tarasicodissa)	Roman general of Isaurian origins; son-in-law of Leo I, father of Leo II	c.425	Co-emperor: 9 February 474 Appointed by his son Leo II Sole Emperor: 17 November 474 Succeeded upon the death of Leo II	9 January 475 Deposed by Basiliscus, brother-in-law of Leo I	9 April 491	An Isaurian chieftain, he gave his support to Leo I to overthrow Aspar. In exchange, he was allowed to marry Leo I's daughter Ariadne, by whom he had a son, Leo II. After the latter's death, he took the throne. Unpopular due to his barbarian origins, he was deposed by his mother-in-law, Verina, and her brother Basiliscus.
Basiliscus ( Flavius Basiliscus )	Army General; brother-in-law of Leo I		9 January 475 Seized power from Zeno	August 476 Deposed by Zeno	476/477	The brother of Leo I's wife, Verina. He was favoured by Leo I, who made him the leader of an expedition against Carthage. The expedition failed, however, Initially popular, Basiliscus alienated the Constantinopolitan population, and his own followers, partly through misfortunes of chance, partly through callous treatment of his allies and his support for the Monophysite Heresy. He was betrayed by his allies, and defeated when Zeno returned to the city with an army. He was then starved to death.
Zeno, restored ( Flavius Zeno ) (Born Tarasicodissa)	Roman general of Isaurian origins; son-in-law of Leo I, father of Leo II	c.425	restored August 476 Having deposed Basiliscus	9 April 491		He rallied an army and restored himself by force. Shortly afterwards, he formally reunited the Roman Empire upon the deposition of the Western Emperor Romulus Augustulus, although in reality the West fell under barbarian control. He ruled laxly, but he left the East stronger than he had found it.
Anastasius I ( Flavius Anastasius )	Palace official ("Silentiarius"); son-in-law of Leo I	c.430	11 April 491 Chosen by Ariadne, widow of Zeno	9 July 518		He was a reputable palace official chosen by Ariadne (daughter of Leo I, widow of Zeno) to succeed; the pair then married. He was at first popular due to his lowering of taxation; he lost popularity when he adopted a strong monophysite policy in his final years. His leadership in war led to an exhaustive conflict between the Romans and the Persians, resulting in little benefit; he also faced ravaging of the Balkans by Slavic and Bulgar invasions.

[edit] Justinian dynasty (518-602)

Name	Status	Birth	Emperor from	Emperor until	Death	Notes
Justin I (Flavius Iustinus )	General, commander of the City Guards under Anastasius I	c.450	July 518 Elected by army and people upon the death of Anastasius I	1 August 527		He was an illiterate Illyrian peasant, who rose to become commander of the city guards. Through this position and lavish bribery, he secured the throne upon the death of Anastasius I. His reign was marked mainly by conflict with the Ostrogoths and Persians.
Justinian I (Flavius Petrus Sabbatius Iustinianus)	Nephew and heir of Justin I	482/483	1 August 527 Inherited the throne on the death of Justin I	13/14 November 565		The son of Justin I's sister, Vigilantia, he was adopted by his uncle, then a rising officer of the army, and brought to Constantinople where he was given a good education. He married in 525 Theodora, a shrewd and capable courtesan who acted as the power behind the throne whilst she lived. Often referred to as the last "Roman" emperor Justinian reconquered large swathes of territory in Italy and the Adriatic coastline, North Africa, and Spain, destroying many of the conquered territories in the process. Justinian also ordered the construction of the Hagia Sophia patriarchal basilica in 532. This "Renewal of the Empire", however, was ended by an outbreak of the so-called Plague of Justinian across Europe, killing much of the Empire's population, and seriously weakening it. Against Justinian's credit of restoring Roman rule in parts of the west, and his work on creating the "Corpus Juris Civilis", must be set the dire legacy he left his heir, Justin II: a hugely reduced army, a crippled economy, and over-stretched resources.
Justin II (Flavius Iustinus Iunior)	Nephew and heir of Justinian I	c.520	14 November 565 Inherited the throne on the death of Justinian I	5 October 578		The son of Justinian I's sister, Vigilantia, he inherited the throne upon his uncle's death. He proved a dismal successor to Justinian: in 568, Italy was overrun by the Lombards; his refusal to pay tribute to the Avars led to a number of unsuccessful campaigns against them; and he lost Syria to the Persians. The stresses of his duties proved too much, and, after making his friend and general Tiberius co-Emperor, he lapsed into insanity.
Tiberius II Constantine (Flavius Tiberius Constantinus)	"Comes" of the Excubitors, friend and adoptive son of Justin II	c.520	5 October 578 Became full Emperor on the death of Justin II	14 August 582 possibly poisoned by Maurice		A friend of Justin II, he was adopted and made co-emperor in 574, upon the advice of the Empress Sophia. He thereafter ruled with the Empress until Justin's death in 578. During his reign, the Persians were defeated in Armenia, whilst the Roman territories in Spain and Africa were secured. However, he was unable to prevent Slavic invasions of the Balkans. He named his son-in-law, Maurice, heir when he became ill in 582; his death shortly afterwards was attributed by rumour to poison.
Maurice (Flavius Mauricius Tiberius)	Commander-in-chief of Cappadocian origins; son-in-law of Tiberius II	539	14 August 582 Succeeded upon the death of his father-in-law Tiberius II	November 602 Forced to abdicate by Phocas	27 November 602 Executed by Phocas	One of Constantinople's outstanding generals, he successfully defeated the Persians in 581. He married Constantina, the daughter of Tiberius II in 582, and in the same year became Emperor upon Tiberius' death. He continued the Persian war until 591, when he secured peace by placing the exiled Sassanid heir Khosrau II on the Persian throne. He also warred mostly successfuly with the Avars and Slavs, and instituted the system of the "Exarchates" in Italy and Africa, allowing greater competence in defending Roman territory there. A refusal to pay a ransom demanded by the Avars in exchange for several thousand captured Roman soldiers led to the rebellion of Phocas, who had Maurice executed. His reign saw the last flowering of Roman power, and a weakening of both the Empire and Persia.

	Phocas (Flavius Phocas )	sub-altern in the Balkan army, leader of rebellion; deposed Maurice	?	November 602 Seized power in a rebellion against Maurice	610 Executed by Heraclius		A minor soldier in the Roman army, he led a rebellion against Maurice after the latter ordered the exhausted forces to winter on the unprotected side of the Danube, and then tried to send them on a winter campaign. In the ensuing rebellion, Maurice abdicated; Phocas had himself crowned Emperor, and then executed the ex-emperor and his children. He was initially popular due to his lowering of taxes and his reforms. However, under his rule, the traditional Roman borders in the east began to collapse, whilst the Persians supported rebellions on their border and advanced their control westwards. Eventually, his authority crumbled, and Heraclius proclaimed himself as Emperor and seized control, executing Phocas.

[edit] Heraclian dynasty (610-711)

Name	Status	Birth	Emperor from	Emperor until	Death	Notes
Herakleios (Ηράκλειος, Hērakleios) Heraclius (Flavius Heraclius)	son of Exarch Heraclius the Elder; deposed Phocas	c.575	5 October 610 Seized power in a rebellion against Phocas	11 February 641		He rebelled against Phocas and seized power. After a long war with the Sassanid Empire and the Avars, he emerged victorious, fatally weakening both opponents. He was unable to prevent the loss of Syria, Palestine and Egypt to the newly emergent Arab Caliphate towards the end of his reign. He is credited with organising the system of Themata to defend the Empire, and with making Greek rather than Latin the official language of the Empire. He left the Empire to be ruled jointly by his two sons Constantine III and Heraklonas
Constantine III (Ηράκλειος (νέος) Κωνσταντίνος, Herakleios Novos Kōnstantinos) Constantine III ( Heraclius Novus Constantinus )	eldest son of Herakleios	3 May 612	11 February 641 Succeeded to throne with Heraklonas following death of Herakleios	24/26 May 641 Tuberculosis, allegedly poisoned by Martina		He was made co-Emperor with his father in 613, but did not fully accede until his father's death. He died shortly after his accession, his sole noteworthy act being bribing the army to safeguard the rights of his son, Constans II. The rumour that his stepmother, Martina, had poisoned him led to the downfall of herself and her son, Heraklonas
Heraklonas (Κωνσταντίνος Ηράκλειος, Kōnstantinos Herakleios) Heraclianus (Constantinus Heraclius)	younger son of Herakleios	626	11 February 641 Succeeded to throne with Constantine III following death of Herakleios	September 641 Deposed by Senate	c.641 Presumed to have died in exile	He was made co-Emperor with his father in 638, but did not fully accede until his father's death. After his brother's death, he ruled briefly as co-emperor, then made his nephew, Constans II, co-emperor, to quell an army revolt. The people of Constantinople, however, mistrusted him, believing that he and his mother Martina had murdered Constantine III; in September, the Senate deposed him and his mother, subjected both to ritual mutilation (Heraklonas lost his nose, Martina lost her tongue), and exiled them to Rhodes.
Constans II (Κώνστας Β', Kōnstas II); born Herakleios Constantine (Ηράκλειος Κωνσταντίνος, Herakleios Kōnstantinos ); called "Constantine the Bearded" (Κωνσταντίνος Πωγωνάτος, Kōnstantinos Pogonatos) Constans II (Constantus II); born Heraclius Constantine ( Heraclius Constantinus ); called "Constantine the Bearded"	son of Constantine III	7 November 630	641 Made co-Emperor by Hereklonas, sole emperor in that same year	15 September 668 Assassinated, possibly on the orders of Mezezius		His uncle, Heraklonas, made him co-emperor to quell a revolt; the revolt continued, and Heraklonas was deposed. Constans then ruled as sole emperor. In his reign, Egypt was lost completely by the Empire, whilst Carthage was also lost for a time. He stabilised the border in the Balkans. His religious attitudes led him to bring Pope Martin I to trial in Constantinople for his criticism of Constans. After executing his brother, Theodosius, he became hated by the people of Constantinople, and left for Syracuse; he spent the rest of his life in Italy. Rumours that he intended to establish Syracuse as his capital led to his being assassinated in his bath. A noble of the court, Mezesius, then established a military regime in Sicily for several months.
Mezezius	Usurper Emperor	Unknown	668	669		A member of the Gnuni family. Declared Emperor in Sicily and ruled there for seceral months. Killed in conflict with Constantine IV.
Constantine IV (Κωνσταντίνος, Kōnstantinos) Constantine (Constantinos)	son of Constans II	652	15 September 668 succeeded following murder of Constans II	September 685 Died of dysentery		He became Emperor following the murder of his father; immediately, he was forced to suppress a revolt in Sicily, led by the imperial pretender Mezezius. In his reign, Constantinople was attacked by an Arab fleet between 672 and 678; Greek fire was used to drive them off. However, several coastal cities, including Smyrna and Cyzicus, were conquered by the Arabs, whilst the Bulgars took advantage of the situation to establish a state in Moesia, to which Constantine was forced to pay tribute. His reign also saw the formal condemnation of monothelitism by the Sixth Oecumenical Council.
Justinian II	son of Constantine IV	669	Co-emperor in 681, sole emperor in 685.	695 Deposed by military revolt	December 711	Augmented the sum paid by the Umayyad Caliphate as an annual tribute, regained control of part of Cyprus.

Leontios	Usurper Emperor	Unknown	695	698 Deposed by military revolt	705	A strategos from Isauria. Used the army of the Helladic Theme to depose Justinian II. Lost Carthage to Abd al-Malik of the Umayyad Caliphate. Briefly resumed control of the city but the Battle of Carthage firmly established Umayyad control over the Exarchate of Africa. The remnants of the defeated Byzantine expedition revolted against Leontius and deposed him. Executed by Justinian II in 705.
Tiberios III	Usurper Emperor	Unknown	698	705 Deposed by a Bulgarian-supported revolt	705	An army officer of Germanic origins. Led remnants of the defeated army expedition for Carthage to successful revolt. War with Abd Al-Malik continued with incoclusive victories and losses for either side.

Justinian II	son of Constantine IV	669	705	711 Deposed by military revolt	December 711	Restored to the throne by winning the military support of Tervel of Bulgaria. Rewarded Tervel with a number of territories in the Balkans. Attempted to regain said territories by attacking Tervel in 708. The expedition failed and peace was restored. The Ummayyads managed to capture Cilicia and penetrated into Cappadocia. Inflicted harsh punishments to the city of Cherson which had served as his exile place for several years. The troops of Cherson revolted against him. He led his own troops against the rebels, fell into their hands and was swiftly executed.

Plagued by economic difficulties, the state treasury accumulated more than seven times less revenue (in nominal coins) than it had done previously. His economic measures included the dismantling of the Byzantine navy, never to be restored to its former strenghth of numbers. The empire grew increasingly depended on the rival republics of Venice and Genoa for naval support. The empire suffered from Turkish advances in Asia Minor throughout the reign, losing Prusa and much of Bithynia by 1326 to the rising Ottoman Dynasty. His second wife Eirene of Montferrat effectively established her own court in Thessalonica from 1303 to 1317. Theodore Svetoslav of Bulgaria conquered much of northeastern Thrace in c. 1305-1307.

However, Orhan I of the Ottoman Dynasty defeated Andronikos III at Pelekanos in 1329, took Nicaea in 1331 and Nicomedia in 1337. After that, only Philadelpheia and a handful of ports remained under Byzantine control in Asia Minor.

Anna declared Kantakouzenos an enemy of the state and offered his title of prefect of Constantinople to Apokavkos. Kantakouzenos answered by declaring himself rival emperor, initiating a civil war which would last until 1347. Ivan Alexander of Bulgaria soon allied with the faction under John V and Anna while Stefan Uroš IV Dušan of Serbia sided with John VI. Both rulers were actually taking advantage of the civil war for their own political and territorial gains. In time John VI would ally himself with Orhan I of the nascent Ottoman Sultanate. Anna was attempted to gain support from Western Europe and in Summer, 1343 an emissary proclaimed her loyalty to Pope Clement VI in Avignon.
