During the rule of Emperor Justinian, the Corpus juris civilis was important because it set the foundation for many law systems.
What is Corpus Juris Civilis?
The collection of foundational legal treatises known today as the Corpus Juris Civilis was published from 529 to 534 on Justinian I, the Byzantine Emperorcommand. It is also sometimes referred to by one of its components, the Code of Justinian, as a metonym. The Justinian code consists of four books:
(1) Codex Constitutionum,
(2) Digesta, or Pandectae,
(3) Institutiones, and
(4) Novellae Constitutiones Post Codicem.
The work was written and distributed almost entirely in Latin, which was still the Eastern Roman Empire's official language in 529–534, as opposed to Greek, which was most often spoken by merchants, farmers, sailors, and other commoners.
