Despite Hammurabi’s various army successes, southern Mesopotamia had no natural, defensible borders, hence managed to get prone to attack. Adopting the loss of Hammurabi, their kingdom started initially to disintegrate quickly. Around his replacement Samsu-iluna (1749-1712 BCE), this new far southern area out-of Mesopotamia was shed to a local Akkadian king, named Ilum-ma-ili, and became the fresh Sealand Dynasty; they stayed free from Babylon for another 272 decades.
Both Babylonians in addition to their Amorite rulers had been motivated out-of Assyria into the north by an enthusiastic Assyrian-Akkadian governor called Puzur-Sin, c. 1740 BCE.
