How long did the Sumerians rule?

The Sumerians are believed to have established one of the first urban civilizations around 4500 BCE, with their influence peaking between 2900 and 2334 BCE. They were eventually absorbed into the Akkadian Empire after Sargon of Akkad conquered the region around 2334 BCE. While Sumerian culture and innovations continued to influence subsequent civilizations, their political dominance effectively ended with the rise of the Akkadians and later empires. Thus, their rule spanned roughly 1,500 years.
