In its ninth year of reign, the cottages (Kashushu), an East Village whose origins are known very little, they descended upon Babylon, perhaps pressured by the movements of Indo-European peoples. Samsu-Iluna could deal with them, even though the situation of this invasion was exploited by some cities (Ur, Larsa, Uruk) Mesopotamian South who revolted, action that was echoed in most northern cities (Isin, Eshnunna). More serious was the emancipation of southern Sumer, where around 1735 BC was a native dynasty, known as the "Dynasty of the country of the sea", formed by Sumerians and akkadians waste. Despite the efforts made, he/she could not prevent that by the North such an Adasi, son of no one, put in Assur which this city escaped, therefore the control of Samsu-Iluna, who could, however, dominate the Middle Euphrates (struggles against Muti-Khurshana). Likewise, the imperial city was attacked by the Kutir-Nakhkhunte Ielamita, although he/she could be expelled at the expense of great losses.
