The earliest of these centres of power to develop foreign empire was also that destined, after many vicissitudes, to hold it latest, because it was the best endowed by nature to repair the waste which empire entails. This was the region which would be known later as Babylonia from the name of the city which in historic times dominated it, but, as we now know, was neither an early seat of power nor the parent of its distinctive local civilization. This honour, if due to any one city, should be credited to Ur, whose also was the first and the only truly "Babylonian" empire.
