Justinian I

Justinian I, born Petrus Sabbatius in 482 in Tauresium, Dardania, was an Eastern Roman emperor who reigned from 527 to 565. His ambitious reign, often termed the 'renovatio imperii' (restoration of the Empire), sought to reclaim territories of the defunct Western Roman Empire. Under his general Belisarius, the Vandal Kingdom in North Africa was conquered, followed by the Ostrogothic Kingdom in Italy, restoring Dalmatia, Sicily, Italy, and Rome to the empire. His general Narses also helped in these campaigns. The southern Iberian Peninsula was also reclaimed, establishing the province of Spania. These military successes significantly increased the Empire's revenue. Justinian is most remembered for his comprehensive reform and codification of Roman law, known as the Corpus Juris Civilis. This legal compilation, consisting of the Codex Justinianeus, Digesta, Institutiones, and Novellae, remains the basis of civil law in many modern legal systems. His reign also witnessed a flourishing of Byzantine culture and a significant building program. The Hagia Sophia, commissioned by Justinian and rebuilt after the Nika riots, stands as a testament to his architectural patronage and is a masterpiece of Byzantine architecture. Despite his achievements, Justinian's reign was not without challenges. The Nika riots in 532 nearly cost him his throne, and his empire faced recurring incursions by various peoples. The plague of Justinian, an epidemic that ravaged the empire in the 540s, had a devastating demographic impact. Justinian died childless in 565, succeeded by his nephew Justin II.
