Nippur (Sumerian: Nibru, often logographically recorded as 𒂗𒆤𒆠, EN.LÍL, "Enlil City;" Akkadian: Nibbur) was an ancient Sumerian city. It was the special seat of the worship of the Sumerian god Enlil, the "Lord Wind", ruler of the cosmos, subject to An alone. Nippur was located in modern Nuffar 8 kilometers north of modern Afak, Al-Qādisiyyah Governorate, Iraq. It is roughly 200 km south of modern Baghdad and about 100 km southeast of the ancient city of Babylon. Occupation at the site extended back to the Ubaid period (Ubaid 2 – Hajji Muhammed), the Uruk period, and the Jemdet Nasr period. The origin of the ancient name is unknown but different proposals have been made.
