Final answer:
Justinian's Code impacted beyond the Byzantine Empire by influencing the development of European legal systems and contributing to the creation of international law.
Step-by-step explanation:
Justinian's Code, formally known as the Corpus Juris Civilis, had a significant impact beyond the Byzantine Empire as it provided the foundation for many legal systems in Europe. After revising and codifying Roman laws and legal opinions, the Code served to unify legal practices within the empire and subsequently influenced the development of the civil law systems of modern Europe. Its architecture for legal principles and its preservation of Roman legal thought became cornerstones for the later establishment of international law.
