Lugal-Zage-Si of Umma (reigned ca. 2359 BC–2335 BC short chronology) was the last Sumerian king before the conquest of Sumer by Sargon of Akkad and the rise of the Akkadian Empire, and was considered as the only king of the third dynasty of Uruk. Lugal-Zage-Si himself also pursued an expansive policy, and he conquered Lagash. Lugal-Zage-Si began his career as King of Umma, from where he conquered several of the Sumerian city-states including Uruk, where he established his capital, and was arguably the first king to unite Sumer as a single kingdom. He overthrew king Urukagina of Lagash and created a unified Mesopotamian Empire, which he ruled over for 25 years.
