Code of Justinian in the context of "Institutes of Justinian"

The Corpus Juris (or Iuris) Civilis ("Body of Civil Law") is the modern name for a collection of fundamental works in jurisprudence, enacted from 529 to 534 by order of Byzantine Emperor Justinian I. It is also sometimes referred to metonymically after one of its parts, the Code of Justinian.

The work as planned had three parts: the Code (Codex) is a compilation, by selection and extraction, of imperial enactments to date; the Digest or Pandects (the Latin title contains both Digesta and Pandectae) is an encyclopedia composed of mostly brief extracts from the writings of Roman jurists; and the Institutes (Institutiones) is a student textbook, mainly introducing the Code, although it has important conceptual elements that are less developed in the Code or the Digest. All three parts, even the textbook, were given force of law. They were intended to be, together, the sole source of law; reference to any other source, including the original texts from which the Code and the Digest had been taken, was forbidden. Nonetheless, Justinian found himself having to enact further laws; today these are counted as a fourth part of the Corpus, the Novellae Constitutiones (Novels, literally New Laws).

Berytus (/ˈbɛrɪtəs, bəˈraɪtəs/; Phoenician: 𐤁𐤓𐤕, romanized: Biruta; Ancient Greek: Βηρυτός, romanized: Bērytós; Latin: Bērȳtus; Arabic: بَيرُوتَ), briefly known as Laodicea in Phoenicia (Ancient Greek: Λαοδίκεια ἡ ἐν Φοινίκῃ; Arabic: لاذقية كنعان) or Laodicea in Canaan from the 2nd century to 64 BC, was the ancient city of Beirut (in modern-day Lebanon) from the Roman Republic through the Roman Empire and Early Byzantine period/late antiquity. Berytus became a Roman colonia that would be the center of Roman presence in the Eastern Mediterranean shores south of Anatolia.

The veterans of two Roman legions under Augustus were established in the city (the fifth Macedonian and the third Gallic), that afterward quickly became Romanized. It was the only fully Latin-speaking city in the Syria-Phoenicia region until the fourth century. Although Berytus was still an important city after earthquakes, around 400 AD Tyre was made the capital of the Roman province of Phoenicia. "Of the great law schools of Rome, Constantinople, and Berytus", the law school of Berytus stood "pre-eminent". The Code of Justinian (one part of the Corpus Juris Civilis, the codification of Roman law ordered early in the 6th century AD by Justinian I and fully written in Latin) was mostly created in this school.
