Did all Mesopotamia city state have a religious ruler called a shaman?

Not all Mesopotamian city-states had a religious ruler specifically called a shaman. Instead, many city-states were governed by kings or priest-kings who held both political and religious authority. While shamans, or similar religious figures, may have existed, the primary leadership structure typically revolved around these rulers who managed both the civic and spiritual needs of their communities. The role of religion was significant, but it was often integrated into the broader governance rather than being solely represented by shamans.
