Ensi (cuneiform: ππΌπ pa.te.si Sumerian: ensik, "lord of the plowland"; Emesal dialect: umunsik; Akkadian: iΕ‘Ε‘akkum) was a Sumerian title designating the ruler or prince of a city-state. Originally it may have designated an independent ruler, but in later periods the title presupposed subordinance to a lugal.
For the Early Dynastic Period (about 2800β2350 BC), the meaning of the titles en, ensi and lugal cannot be differentiated clearly: see lugal, ensi and en for details. Ensi may have originally been a designation of the ruler restricted to Lagash and Umma. The ensi was considered a representative of the city-state's patron deity. In later periods, an ensi was normally seen as subordinate to a lugal. Nevertheless, even the powerful rulers of the Second Dynasty of Lagash (c.β2100 BC) such as Gudea were satisfied with the title ensi.
