Sargon's vast empire is known to have extended from Elam to the Mediterranean Sea, including Mesopotamia, parts of modern-day Iran and Syria, and possibly parts of Anatolia and the Arabian peninsula. He ruled from a new capital, Akkad, which the Sumerian king list claims he built on the left bank of the Euphrates. 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.
