However, the Sumerians remained generally dominant until the rise of the Akkadian Empire (2335–2124 BC), based in the city of Akkad in central Iraq. Sargon of Akkad, originally a Rabshakeh to a Sumerian king, founded the empire, he conquered all of the city states of southern and central Iraq, and subjugated the kings of Assyria, thus uniting the Sumerians and Akkadians in one state. He then set about expanding his empire, conquering Gutium, Elam and had victories that did not result into a full conquest against the Amorites and Eblaites of Ancient Syria.
