Emperor Justinian wanted to save in writing all the laws that began in ancient Rome. In ancient Rome, the laws were called the Twelve Tables. Emperor Justinian collected up all the old laws, and added new ones that have his people even more rights. He called this the body of law the Code. One of the laws in Justinian's Code stated that a person was innocent until proven guilty. Justinian wrote laws that were fair for everyone because, he thought about the needs of all the people.
