Ishma-Dagan

Ishma-Dagan (, Ish-ma-Dda-gan; died 2154 BC) was a ruler of the city of Mari, one of the military governors known as Shakkanakku in northern Mesopotamia, in the later period of Akkad. According to the dynastic lists, he ruled for 45 years, after Shu-Dagan, and was the third Shakkanakku ruler. Ishma-Dagan was probably contemporary with the Akkadian ruler Shar-Kali-Sharri. He had two sons who succeeded him in turn as Shakkanakkus of Mari: Nûr-Mêr and Ishtup-Ilum.
