Ziggurat of Ur in the context of "Shulgi"

Ur (/ʊr/ or /ɜːr/) was a major Sumerian city-state in ancient Mesopotamia, located at the site of modern Tell el-Muqayyar (Arabic: تَلّ ٱلْمُقَيَّر, lit. 'mound of bitumen') in Dhi Qar Governorate, southern Iraq. Although Ur was a coastal city near the mouth of the Euphrates on the Persian Gulf, the coastline has shifted and the site is now well inland, on the south bank of the Euphrates, 16 km (10 mi) southwest of Nasiriyah in modern-day Iraq. The city dates from the Ubaid period c. 3800 BC, and is recorded in written history as a city-state from the 26th century BC, its first recorded king being Mesannepada.

The city's patron deity was the moon god Nanna (Sin in Akkadian), and the name of the city is derived from UNUG, literally "the abode (of Nanna)". The site is marked by the partially restored ruins of the Ziggurat of Ur, which contained the shrine of Nanna, excavated in the 1930s. The temple was built in the 21st century BC (short chronology), during the reign of Ur-Nammu and was reconstructed in the 6th century BC by Nabonidus, the last king of Babylon.

Ennigaldi-Nanna's museum is the earliest known public museum. It dates to circa 530 BCE. The curator was Ennigaldi, the daughter of Nabonidus, the last king of the Neo-Babylonian Empire. It was in the state of Ur, in the modern-day Dhi Qar Governorate of Iraq, roughly 150 metres (490 ft) southeast of the famous Ziggurat of Ur.

Ur-Nammu (or Ur-Namma, Ur-Engur, Ur-Gur, Sumerian: 𒌨𒀭𒇉; died c. 2094 BC) founded the Sumerian Third Dynasty of Ur, in southern Mesopotamia, following several centuries of Akkadian and Gutian rule. Though he built many temples and canals his main achievement was building the core of the Ur III Empire through military conquest. Ur-Nammu is chiefly remembered today for his legal code, the Code of Ur-Nammu, the oldest known surviving example in the world. He also initiated the construction of the Ziggurat of Ur. He held the titles of "King of Ur" and "King of Sumer and Akkad". His personal goddess was Ninsuna.
