531 EMPEROR JUSTINIAN (527-565) (Byzantine Empire)
Ruled that Jews cannot testify against Christians. He also censored part of the synagogue liturgy for being anti-trinitarian. Justinian is famous for his Codex Justinianeus (Corpus Juris Civilis), which he began in 527, as well as his new regulations known as Novels (Novellae Constitutiones Post Codicem). In his Codex and Novellae, he revised many of the older ordinances and added some of his own. These included new anti- Jewish imperial directives and restrictions. In general, his code united church and state making anyone who was not connected to the Christian church a non- citizen. These regulations determined the status of Jews throughout the Empire for hundreds of years.
