The first great code was that drawn up by a commission appointed by Theodosius II in the year 435. The work was completed in 438 and comprised all the leges generales since the time of Constantine the Great. This Code was declared in force in both the Western and Eastern Empires. The arrangement of the Code is far inferior to that of its successor, the Justinian Code. In the East the Theodosian Code remained in force until supplanted by the Justinian Code in the sixth century. In the West it survived the fall of Rome and largely served as a basis for the Romano-Barbarian Codes.
