Why was power given to kings by the sumerian city states?

In Sumerian city-states, power was granted to kings primarily due to their role as military leaders, religious figures, and overseers of agricultural production. Kings were often seen as representatives of the gods, lending divine legitimacy to their authority. This combination of military strength, religious significance, and administrative responsibility allowed them to maintain order, protect the city-state, and ensure prosperity, which the populace relied upon. As a result, kings became central figures in Sumerian society, wielding considerable power.
