Answer: The Akkadians managed to unite Mesopotamian city-states
Explanation: Under the rule of Sargon and subsequent kings of the kingdom, the Akkadian Empire, which is considered the first acknowledged empire in history, reached a peak around the 22nd century BCE.
By conquering other countries to divide them into a single Mesopotamian empire, Sargon created the Akkadian empire and replaced existing Akkadian noble people to replace rulers.
In the west and over Elam in the east, the Akkadian empire stretched up to the Mediterranean Sea.
