Justinian I

Justinian I (jŭstĭnˈēən), 483–565, Byzantine emperor (527–65), nephew and successor of Justin I. He was responsible for much imperial policy during his uncle's reign. Soon after becoming emperor, Justinian instituted major administrative changes and tried to increase state revenues at the expense of his subjects. Justinian's fiscal policies, the discontent of the Monophysites at his orthodoxy, and the loyalty of the populace to the family of Anastasius I produced the Nika riot (532), which would have cost Justinian his throne but for the firmness of his wife, Empress Theodora, and the aid of his great generals, Belisarius and Narses (see Blues and Greens). Justinian, through Belisarius and Narses, recovered Africa from the Vandals (533–48) and Italy from the Ostrogoths (535–54). He was less successful in fighting the Persians and was unable to prevent the raids of the Slavs and the Bulgars. Justinian's policy of caesaropapism (i.e., the supremacy of the emperor over the church) included not only matters of organization, but also matters of dogma. In 553, seeking to reconcile the Monophysites to the church, he called a council (see Constantinople, Second Council of) but accomplished nothing and finally tended to drift into heresy himself. Justinian's greatest accomplishment was the codification of Roman law, commonly called the Corpus Juris Civilis, executed under his direction by Tribonian. It gave unity to the centralized state and greatly influenced all subsequent legal history. Justinian erected many public works, of which the church of Hagia Sophia is the most notable. He was succeeded by his nephew, Justin II. The writings of Procopius are the main source of information on Justinian's reign.

Justinian I


Born 482 or 483 in Tauresium, upper Macedonia; died Nov. 14, 565, in Constantinople. Byzantine emperor from 527.

The son of a peasant, Justinian was educated under the patronage of his uncle Justin I, who was emperor from 518 to 527. Brought by Justin to the imperial court, Justinian exercised great influence on affairs of state. After ascending to the throne he strove to restore the Roman Empire to its former boundaries and former greatness. Supported by the middle strata of landowners and slaveholders, he also sought the support of the orthodox church; he attempted to limit the senatorial aristocracy’s claims to power. His wife, Theodora, played an important role in state politics.

During Justinian’s reign Roman law was codified (seeCODIFICATION OF JUSTINIAN). The emperor’s legislative activities were on the whole directed toward the establishment of unlimited imperial power, the strengthening of slavery, and the defense of property rights. He contributed to the centralization of the state by his reforms of 535 and 536, which increased the size of administrative districts, concentrated civil and military power in the hands of the districts’ governors, and regulated and strengthened the army and the administration of the state. He placed handicrafts and trade under the control of the state. Oppressive taxation increased under Justinian, and heretics were brutally persecuted.

Justinian was responsible for a vast program of construction. He erected fortifications for defense against barbarian invasions, built up cities, and constructed palaces and churches, including Hagia Sophia in Constantinople.

Justinian’s foreign policy was one of conquest. He regained areas of the Western Roman Empire that had been seized by the barbarians: northern Africa, Sardinia, and Corsica were recovered from the Vandals in 533 and 534, the Italian Peninsula and Sicily from the Ostrogoths between 535 and 555, and the southeastern part of the Iberian Peninsula from the Visigoths in 554. Slaveholding relations were restored in these areas. In the east, the Byzantines waged war against Iran from 527 to 532 and from 540 to 561; in the north they repulsed an attack by the Slavs.

In various regions of the empire, especially in the lands annexed under Justinian, popular uprisings broke out in protest against the emperor’s authority. Notable expressions of unrest were an uprising of Samaritans in Palestine in 529 and 530, the Nika revolt in Constantinople in 532, the revolutionary movement in North Africa from 536 to 548 headed by Stotzas, and the people’s liberation movement in Italy led by Totila.
