Early Old Babylonian period. The period from 2000-1800 BCE is called the Isin-Larsa period, also the Early Old Babylonian period. The archeological period is the Middle Bronze Age. Hegemony in the south was exercised by the dynasty at Isin and usually had the upper hand in political and military matters. Kings of Isin often have Amorite names, the first being the last general under the rule of the last king of Ur-III. Many Amorites obtain high positions and eventually kings of cities. They apparently quickly integrate into the (Akkadian) society and seem to renounce their language, since not much is found in written form.
