Around 1792 BC/BCE, a king named Hammurabi inherited the throne of Babylon from his father. Babylon was a city near Kish (the home of Sargon). At first, Hammurabi only ruled a small area of the land around his own city. But soon he began to conquer some of the smaller cities around him. He convinced the kings of other cities to swear allegiance to him. Soon he ruled over the whole southern part of Mesopotamia. This area was called Babylonia, after the city of Babylon.
