Justinian I

Justinian I (born c. 482 in Tauresium in the Latin-speaking Balkans, reigned 527-565) was the last great emperor of the unified late Roman world and arguably the most consequential ruler of late antiquity. Rising from peasant origins under his uncle Justin I, he pursued an ambitious program of imperial renewal: his generals Belisarius and Narses reconquered Vandal North Africa, Ostrogothic Italy, and part of Visigothic Spain, briefly restoring Roman rule across much of the Mediterranean. His jurists, led by Tribonian, codified centuries of Roman law into the Corpus Juris Civilis (the Digest, Code, and Institutes), the foundation of the entire later Western legal tradition. He rebuilt Constantinople after the Nika riots of 532, crowning it with the church of Hagia Sophia, intervened forcefully in Christological controversy, and ruled alongside his powerful empress Theodora until his death in 565. The letters here, drawn from the Austrasian collection, Cassiodorus, and the correspondence of popes John II and Agapetus I, reflect his diplomatic and doctrinal dealings with the Frankish court, the Ostrogothic regime in Italy, and the papacy.
