Final answer:
The Codex Justinianus, or Code of Justinian, led to the development of two significant bodies of law: civil law, which is applied in many regions globally, and canon law, which governs the Roman Catholic Church. It preserved Roman legal principles and was systematically refined to provide a coherent legal framework.
Step-by-step explanation:
The Codex Justinianus, also known as the Code of Justinian, is a cornerstone of what became known as the Corpus Juris Civilis. This monumental legal compilation was commissioned by Emperor Justinian of the Byzantine Empire. The two main bodies of law derived from the Code of Justinian that have had a profound influence on legal systems are the civil law and the canon law traditions. Civil law systems are present in much of Europe, Latin America, and other parts of the world that were part of the Roman Empire or under its influence. Canon law, on the other hand, is the legal framework that governs the Roman Catholic Church.
Justinian's work had a long-lasting impact: it preserved Roman laws and legal thinking, ensuring that the legal principles of the Roman Empire would endure long after its fall. The Justinian Code was not merely a collection of existing laws; it systematically reviewed, organized, and consolidated Roman law. Justinian's legal experts eliminated contradictions and refined the legal texts to create a clear and coherent body of laws. As a result, the Code of Justinian essentially redefined Roman law and became a crucial reference for the development of subsequent legal systems in many parts of the world.
