Corpus Juris Civilis
The Corpus Iuris Civilis (sometimes also called Corpus Juris Civilis) is a collection of laws regarding Roman civil law. It was first compiled in the 6th century, during the reign of Iustinan I. After the fall of the Roman empire it was mostly forgotten. It was re-discovered in the 11th century. During the Middle Ages it was an important source of civil law for most countries in Europe.
