7 de Abril de 529.

First draft of Corpus Juris Civilis (a fundamental work in jurisprudence) is issued by Eastern Roman Emperor Justinian. The Corpus Juris Civilis (Body of Civil Law) is a fundamental work in jurisprudence, issued from 529 to 534 by order of Justinian I, Byzantine Emperor.

Justinian gave orders to collect legal materials of various kinds into several new codes which became the basis of the revival of Roman law in the Middle Ages. This revived Roman law, in turn, became the foundation of law in all civil law jurisdictions. The provisions of the Corpus Juris Civilis also influenced the canon law of the church since it was said that ecclesia vivit lege romana — the church lives under Roman law.

The work was directed by Tribonian, an official in Justinian's court, and distributed in three parts: Digesta (or "Pandectae"), Institutiones, and the Codex Constitutionum. A fourth part, the Novels (or "Novellae Constitutiones"), was added later.
