Justinian Code is the first complete slavery statute in the world. It systematically collected and arranged all the laws and legal works from Rome to Justinian. It is voluminous and rich in content. It indicates that Roman law itself has developed to an extremely developed and complete stage, which has had a great influence on the development of jurisprudence and jurisprudence in European countries in the future.

In addition, the content and legislative techniques of this code are far more detailed than other slavery laws. The concepts and principles defined by it have the characteristics of rigorous wording, accuracy and clear conclusion, especially the important principles it puts forward, such as the formal equality of free people within the scope of "private law", the main condition for the contract to take effect with the consent of the parties, and the unlimited private ownership of property, which laid the foundation for later laws.
