In 500 C.E. Justinian came up with his code of law called, Justinian's Code. His code was also know as Corpus Juris Cilivis (body of law). This did not constitute a new legal law, instead it included an outline of past codes and the juries opinions about them. It also included Justinian's new laws. His Code consisted of four individual books. One of the four books and the basis of them all was the Codex Constitutionum. This was a book that had 10 books inside of it. Justinian had 10 men go through all the known laws issued by emperors and weed out all the inconsistent material and adapt new provisions to the circumstances of that time. The next book was known as the Digesta. This book was drawn between 530 and 533. The Juries statements were found in this book. The next book was The Institutiones. It was an elementary textbook that contained legal introductions for first-year law students. The fourth and final book was the Novellae Constitutiones Post Codicem, or in English, The Novels. This last book contained several collections of new regulations issued by Justinian himself (Jorge Cauz). A fun fact about Justinian and his code is that Justinian invented the law, "Innocent until proven guilty." We still use this law today.
