Why were priests so important in the Sumer Ian city- states?

Priests were crucial in Sumerian city-states because they served as intermediaries between the gods and the people, performing rituals to ensure divine favor and prosperity. They managed temple complexes, which were central to the economy and social life, and collected offerings that supported both religious activities and community welfare. Additionally, priests often held significant political power, influencing decisions and governance, as their authority was intertwined with religious beliefs and practices.
