The First dynasty of Lagash is dated to the 26th century BCE. En-hegal is recorded as the first known ruler of Lagash, being tributary to Uruk. His successor Lugal-sha-engur was similarly tributary to Mesilim. Following the hegemony of Mesannepada of Ur, Ur-Nanshe succeeded Lugal-sha-engur as the new high priest of Lagash and achieved independence, making himself king. He defeated Ur and captured the king of Umma, Pabilgaltuk. In the ruins of a building attached by him to the temple of Ningirsu, terracotta "bas reliefs" of the king and his sons have been found, as well as onyx plates and lions' heads in onyx reminiscent of Egyptian work. One inscription states that ships of Dilmun (Bahrain) brought him wood as tribute from foreign lands. He was succeeded by his son Akurgal.
