Probably Sargon of Akkad.
From Wikipedia:
http://en.wikipedia.org/wiki/Sargon_of_Akkad
"Sargon is the first individual in recorded history to create a multiethnic, centrally ruled empire, and his dynasty controlled Mesopotamia for around a century and a half."
The man's effect on the world was absolutely incredible.
