Byzantine Law refers to the legal system that developed in the Byzantine Empire, which lasted from the 4th to the 15th century. It was heavily influenced by Roman Law and aimed to provide a comprehensive legal framework for the diverse populations within the empire. The most significant compilation of these laws is the Corpus Juris Civilis, ordered by Emperor Justinian I in the 6th century, which organized and codified existing laws and legal principles. The legal system included various branches, such as public law, private law, and ecclesiastical law, reflecting the empire's complex social structure. Byzantine Law also emphasized the role of the emperor as the ultimate legal authority, blending secular and religious aspects. This legal tradition influenced many modern legal systems in Eastern Europe and the Mediterranean region.
