The Digest, also known as the Pandects, was a compendium or digest of juristic writings on Roman law compiled by order of the Byzantine emperor Justinian I in 530–533 AD. It is divided into 50 books.

Roman law is the legal system of ancient Rome, including the legal developments spanning over a thousand years of jurisprudence, from the Twelve Tables, to the Corpus Juris Civilis ordered by Eastern Roman emperor Justinian I. Roman law forms the basic framework for civil law, the most widely used legal system today, and the terms are sometimes used synonymously. The historical importance of Roman law is reflected by the continued use of Latin legal terminology in many legal systems influenced by it, including common law.
