Sargon I

First known emperor in the ancient world
Emperor of the Akkadian Empire
Sargon forged an empire that reached all the way from the Persian Gulf to the Mediterranean Sea.
The imperial dynasty of Sargon and his descendants lasted less than a century, but many ambitious Mesopotamian rulers later tried to emulate Sargon and take control of the entire region.
Sargon of Akkad (also known as Sargon the Great, Shar-Gani-Sharri, and Sarru-Kan, meaning “True King” or “Legitimate King”) reigned in Mesopotamia from 2334 to 2279 BCE.
His story was long known throughout Mesopotamia where, in time, he came to be considered the greatest man who had ever lived, celebrated in glorious tales down through the Persian Empire, along with his grand-son Naram-Sin. (source: http://www.ancient.eu/Sargon_of_Akkad/#)
