About this source

What it is

The Corpus Juris Civilis is a collection of legal works enacted between 529 and 534 on the order of Emperor Justinian I. It has three main parts: the Code, a compilation of imperial laws; the Digest, extracts from Roman jurists; and the Institutes, a legal textbook. A later fourth part, the Novels, was added after Justinian's death. The project was directed by the official Tribonian.

Why it matters

This codification became the sole legal source for the empire and later the basis of civil law across much of Europe and beyond. It shows Justinian's determination to bring order to a confused legal system and to assert his authority as lawgiver, while revealing the huge bureaucratic effort of officials like Tribonian who carried out the work.

Look closer

  • What does this tell you about the scale of Justinian's government?
  • Who actually wrote the text, and why does that matter when judging whose achievement this is?
