- Hammurabi (/?x�m?‘r??bi/; Old Babylonian Akkadian: ??????????, romanized: ?�mmurapi;[a] c.?1810 � c.?1750 BC), also spelled Hammurapi, was the sixth Amorite king of the Old Babylonian Empire, 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.
