Which civilization's rule over Mesopotamia lasted for about 100 years after 2100 B.C.E.?

The Amorites, who emerged as a significant cultural and political force after the decline of the Sumerians and Akkadians, are recognized for their rule over Mesopotamia that began around 2100 B.C.E. Following the fall of the Third Dynasty of Ur, the Amorites established several city-states, most notably Babylon. Their dominance in the region is exemplified by the reign of King Hammurabi, known for creating one of the earliest and most complete written legal codes. The Amorite period is characterized by the development of trade, art, and literature, influencing the subsequent evolution of Mesopotamian civilization.

The other civilizations mentioned either predate or do not match the specified time frame. The Akkadians were significant earlier in Mesopotamian history but had already declined by 2100 B.C.E. The Sumerians were predominant before the Akkadians and largely fell out of control during the rise of the Amorites. The Hittites, although an important civilization in their context, did not rule over Mesopotamia and are more known for their influence in Anatolia and interactions with neighboring cultures. Therefore, the Amorites are accurately identified as the civilization that governed Mesopotamia for about 100 years after 210
