Sargon's vast empire is thought to have included large parts of Mesopotamia, and included parts of modern-day Iran, Asia Minor and Syria. He ruled from a new, but as yet archaeologically unidentified capital, Akkad, which the Sumerian king list claims he built (or possibly renovated). He is sometimes regarded as the first person in recorded history to create a multiethnic, centrally ruled empire, although the Sumerians Lugal-anne-mundu and Lugal-zage-si also have a claim. His dynasty controlled Mesopotamia for around a century and a half. He is a well known king of the Akkadians.
