Hammurabi

Hammurabi (r. 1792–1750 BC) is famous for codifying the laws of Babylonia into the Code of Hammurabi. He conquered all of the cities and city-states of southern Mesopotamia, including Isin, Larsa, Ur, Uruk, Nippur, Lagash, Eridu, Kish, Adab, Eshnunna, Akshak, Akkad, Shuruppak, Bad-tibira, Sippar, and Girsu, coalescing them into one kingdom, ruled from Babylon. Hammurabi also invaded and conquered Elam to the east, and the kingdoms of Mari and Ebla to the northwest.
