Hammurabi, also spelled Hammurapi, was the sixth Amorite king of Babylon, reigning from c. 1792 to c. 1750 BC. He was preceded by his father, Sin-Muballit, who abdicated due to failing health. During his reign, he conquered the city-states of Larsa, Eshnunna, and Mari. He ousted Ishme-Dagan I, the king of Assyria, and forced his son Mut-Ashkur to pay tribute, bringing almost all of Mesopotamia under Babylonian rule.
