King Sumu Apum:
The Amorite sheikh (Sumu Abum) had founded Babylon in 1880 BC, which emerged as a center of power in the phase of the Amorite city-states with Isin, Larsa, and Eshnunna. Sumu Abum appeared as a man of war when he suppressed the revolts of Kish, Kutha, and Kazalua, and as a man of Imran when he built temples and took care of agriculture and irrigation. Babylon became the most famous city in the ancient world for its civilization, but this did not happen overnight, but rather took several centuries. Thus, Babylon became the capital of the first Babylonian state founded by the Amorites.
Sumo Abum, or Su Abu, the founder of the first Babylonian dynasty and the founder of the first rule in the city of Babylon, who built it and built its walls and made it the capital of his kingdom. He ruled from the years 1830-1817 BC. He was the first to give Babylon this name (God’s Gate), and Sumu Abum descends from the Western tribes ( Amorite) the Semitic who migrated to Sumer and Akkad from the Levant.
