Phocas (Latin: Flavius Focas Augustus; Greek: Φωκᾶς, Phokas; c. 547 – 5 October 610) was Byzantine emperor from 602 to 610. The early life of Phocas is largely unknown, but he rose to prominence in 602, as a leader in the revolt against Emperor Maurice. Phocas captured Constantinople and overthrew Maurice on 23 November 602, and declared himself emperor on the same day. Phocas deeply mistrusted the elite of Constantinople, and therefore installed his relatives in high military positions, and brutally purged his opponents. Phocas was an incompetent leader, both of the administration and army, and under him the Byzantine Empire was threatened by multiple enemies, with frequent raids in the Balkans from the Avars and Slavs, and a Sassanid invasion of the eastern provinces. Because of Phocas' incompetence and brutality, the Exarch of Africa, Heraclius the Elder, rebelled against him. Heraclius the Elder's son, Heraclius, succeeded in taking Constantinople on 5 October 610, and executed Phocas on the same day, before declaring himself the emperor.


Early Life

Flavius Phocas' date of birth is unknown.[1] He and his family were likely of Thraco-Roman origin.[2] The life of Phocas before his usurpation of the Byzantine Empire's throne is obscure, but it is known that he served as a low-ranking officer under Emperor Maurice.


In 602, the Byzantine army rebelled against Emperor Maurice, largely due to exhaustion and outrage over orders to continue campaigning north of the Danube in winter as well as previous cuts in wages. The army declared Phocas, by then a centurion, to be the new emperor, raising him on a shield (the traditional method of declaring emperors) on 23 November 602.[3][4]

Phocas was crowned the new emperor by the patriarch in the church of St John the Baptist at the Hebdomon. Several days afterwards he entered Constantinople unopposed.

Maurice fled the city with his sons, Theodosius and Tiberius, but they were soon after captured and executed. Maurice's wife and daughters were put in the monastery of Nea Metanoia and later killed.[5]

Foreign conflict

Despite the execution of the previous emperor and his dynastic successors, Phocas remained in a precarious position, which led him to devote his energy to purging enemies and destroying conspiracies. Because of this focus, and the local resistance he faced all throughout the Byzantine Empire, he was unable to confront foreign attacks on the empire's frontiers. The Avars and Slavs launched numerous raids into the Balkan provinces of the Byzantine Empire, and the Sassanian Empire launched an invasion of the eastern provinces of the empire.

The Avars were able to take all land in the Balkans north of Thessalonika. The populations of Christian cities were slaughtered or captured. The Byzantines transferred most of their forces to the eastern front due to the threat from the Persians.

The Sassanid Persians had formerly been at peace with Maurice as a result of a treaty they made with him in 591. After Phocas usurped and killed Maurice, the Persians invaded the empire in 603. [3] The Sassanids rapidly occupied the eastern provinces, leading the Magister militum per Orientem, Narses, to defect to their side. Phocas swiftly dealt with him, by inviting him to Constantinople under the promise of safe conduct, then having him burnt alive when he arrived. By 607, the Sassanids had occupied Mesopotamia, Syria, and much of Asia Minor, as far as the Bosphorus.[6]

By the time his reign ended in 610, the Persians had already crossed the Euphrates and taken Zenobia. Contemporary accounts describe the Persians as being very brutal to the occupied population. The 'miracle of St Demetrios' described the carnage:

[T]he devil raised the whirlwind of hatred in all the East, Cilicia, Asia, Palestine and all the lands from there to Constantinople: the factions, no longer content simply to spill blood in public places, attacked homes, slaughtered women, children, the aged, and the young who were sick; those whose youth and frailty impeded their escape from the massacre, [saw] their friends, acquaintances, and parents pillaged, and after all that, even set on fire so that the most wretched inhabitant was not able to escape.[5]


Phocas was an incompetent administrator, who was unable to control either the state or the army effectively.[7] Due to his distrust of the bulk of Constantinople's elite, with whom he had no connection before becoming emperor, Phocas practised nepotism, frequently filling senior military positions with his relatives. He installed: his brother Domentziolus as Magister officiorum in 603; his nephew Domentziolus as Magister militum per Orientem in 604, giving him command over the eastern provinces; and his brother Comentiolus as Magister militum per Orientem around 610. All three remained loyal to Phocas until they were killed by Heraclius.[8] Of the three known male blood-relatives of Phocas, all three were appointed to senior posts, two in military positions and one in an administrative position. Phocas also appointed Priscus, who was his son-in-law by way of his marriage to Phocas' daughter Domentzia, as Comes excubitorum, the captain of the Excubitors, in 603.[9]

Italian policy

The deposition of Phocas 610 AD.

When Phocas was Emperor, Byzantine Italy was under continual attack from Lombards, but the Byzantine government spent few resources to aid Italy due to troubles elsewhere. In the entirety of Phocas' reign the only public building built with government money in the city of Rome was a statue of Phocas completed in 608.[5]

When Phocas usurped Maurice, Gregory the Great was bishop of Rome and he praised Phocas as a restorer of liberty. Gregory referred to him as a pious and clement lord, and compared his wife (the new Empress) Leontia to Marcian's consort Pulcheria (whom the Council of Chalcedon called the new Helena). In May 603, portraits of the imperial couple arrived in Rome and were ordered by the pope to be placed in the oratory of St Caesarius in the imperial palace on the Palatine.[5]

Imperial approval was needed in that time to appoint a new pope, but the approval was delayed by a year upon the death of Pope Sabinian in 606, as Phocas was occupied with killing internal enemies that threatened his rule.[5] He finally gave approval in 607 and Boniface III became pope. Phocas declared Rome "the head of all churches".[5]


Miniature 41 from the Constantine Manasses Chronicle, 14 century: Usurper Phocas and the assault against him from the armies of Heraclius.

Despite being appointed as Comes excubitorum, Priscus was not loyal to Phocas, and in 608 he appealed to Heraclius the Elder, the Exarch of Carthage, to rebel against Phocas.[9] Heraclius the Elder agreed, and began to prepare to invade, by cutting off the supply of grain to Constantinople and assembling a large army and navy. Heraclius the Elder launched his invasion in 609, with his cousin, Nicetas, marching troops overland to the capital, and his son, Heraclius, leading a naval invasion of Thessaloniki, before marching to Constantinople. Heraclius arrived outside Constantinople on 3 October 610, and seized the city on 5 October. Heraclius was declared emperor on the same day, and swiftly had Phocas executed.[10]


Phocas is generally depicted as a villain by Byzantine and modern historians alike, but some of the earliest sources available about Phocas’ reign were written during the reign of Heraclius. The writings that survive aren’t reliably neutral and the writers would have good reason to demonize him in order to strengthen the rule of Heraclius.[11]

In the cultural sphere, the reign of Phocas is marked by the change of Imperial fashion set by Constantine the Great. Constantine and all his successors, except Julian the Apostate, were beardless. Phocas again introduced the wearing of the beard. This fashion lasted until the end of the Byzantine Empire.[12]
