Detailed explanation-1: -The Empire of Akkad collapsed in 2154 BCE, within 180 years of its founding.

Detailed explanation-2: -The Akkadian period is generally dated to 2334–2154 BC (according to the middle chronology). The short-chronology dates of 2270–2083 BC are now considered less likely. It was preceded by the Early Dynastic Period of Mesopotamia (ED) and succeeded by the Ur III Period, although both transitions are blurry.

Detailed explanation-3: -Sargon declared himself ruler of Kish and Uruk, gradually conquering each of the Sumerian city-states. Sargon was ruler over his empire for just over fifty years, from 2334 B.C.E. to 2279 B.C.E.
