What was the Codex Justinianus?

The Codex Justinianus, or Code of Justinian, is a central component of the Corpus Juris Civilis, a comprehensive codification of Roman law ordered by Eastern Roman Emperor Justinian I in the sixth century AD. It served as a uniform rewriting of existing Roman laws and laid the foundational framework for civil law systems in many modern states. Alongside the Code, the broader legal collection eventually encompassed the Digest, the Institutes, and later the Novellae Constitutiones.
