The higher powers
Caracalla's edict shows the great legislative power of the emperor. Because of thus power also the function of the Senate changed in the imperial period. In first case they were an advisory body to the king, consuls. However, they became a body that also could make laws.

The literary and practical achievements of the jurists of this period gave Roman law its unique shape.
The new concepts and legal institutions developed by jurists are too numerous to mention here. Therefore, we can only give a few
