Answer:
Justinian's Proceedings.
Explanation:
The Proceedings of Emperor Justinian had a great influence on the future development of law. Its impact is greater in Europe and smaller in Asia. The legal systems of many modern countries are still based today on the elements of Justinian law. Already at the beginning of his reign, Justinian sought to reform Roman law, which had changed a great deal over time. Some fragments of legal acts before the reform were recounted, and many of them contained earlier acts of slavery. At the time of the creation of the law, and even later, the Roman Empire was more feudal than the slave. Justinian's Proceedings are the foundation of modern law.
Well what ended the civil war was the surrender of Lee at Appomattox so the answer is A. [i can only see half of the question by the way.]
