Corpus Juris is a Latin term meaning "body of law." It refers to a comprehensive collection of legal texts and principles that serve as a foundation for legal systems. The most notable example is the Corpus Juris Civilis, compiled under the Byzantine Emperor Justinian I in the 6th century, which organized and codified Roman law. This compilation consists of four main parts: the Digest, the Institutes, the Codex, and the Novellae. The Corpus Juris Civilis has significantly influenced many modern legal systems, particularly in countries that follow civil law, shaping the way laws are interpreted and applied today.
