SUBAHU
/ SUMU-ABUM
Sumu-abu
/ Su-abu / Subahu / Sumu-Abum was an Amorite, and the first King
of the First Dynasty of Babylon (the Amorite Dynasty). He reigned
from 1830-1817 BC (short chronology) / 1897-1883 BC (middle chronology).
He freed a small area of land previously ruled by the fellow Amorite
city state of Kazallu which included Babylon, then a minor administrative
center in southern Mesopotamia. Sumu-Abum (and the three Amorite
kings succeeding him) makes no claim to be King of Babylon, suggesting
that the town was at this time still of little importance.
