Justinian I

Justinian I faced a major uprising in Constantinople, the Nika Riots, which threatened his rule. Empress Theodora urged him to stay, and General Belisarius crushed the revolt, killing an estimated 30,000 people and solidifying Justinian's autocratic power.

Byzantine forces under General Belisarius defeated the Vandal Kingdom in North Africa. Justinian's reconquest restored Roman control over the region, including Carthage, and eliminated the Vandal threat to Mediterranean trade.

Justinian I commissioned the codification of Roman law, resulting in the Corpus Juris Civilis. This compilation of legal texts preserved and systematized Roman jurisprudence, becoming the foundation for civil law in many European countries.

Justinian I inaugurated the Hagia Sophia in Constantinople, a monumental domed church designed by Anthemius of Tralles and Isidorus of Miletus. It served as the center of Eastern Orthodox Christianity for nearly a millennium and influenced Byzantine and Ottoman architecture.

Byzantine forces captured Ravenna, the capital of the Ostrogothic Kingdom in Italy. This victory, part of the Gothic War, restored Roman rule over the Italian peninsula after decades of Ostrogothic control.
