Did nippur have a king and queen?

Nippur, an important ancient Sumerian city, did not have a king and queen in the same way that many other city-states did. Instead, it was primarily a religious center, dedicated to the worship of the god Enlil, and was governed by a priestly hierarchy. While there may have been local rulers or governors, Nippur's significance lay more in its religious authority than in a traditional royal lineage.
