From 529 to 534 AD the Byzantine Emperor Justinian I codified and consolidated Roman law up until that point, so that what remained was one-twentieth of the mass of legal texts from before. As one legal historian wrote, “Justinian consciously looked back to the golden age of Roman law and aimed to restore it to the peak it had reached three centuries before.” The Justinian Code remained in force in the East until the fall of the Byzantine Empire. Western Europe, meanwhile, relied on a mix of the Theodosian Code and Germanic customary law until the Justinian Code was rediscovered in the 11th century, and scholars at the University of Bologna used it to interpret their own laws. Both these codes influenced heavily not only the law systems of the countries in continental Europe (e.g. Greece), but also the Japanese and Korean legal traditions.
