A Major Mesopotamian City
Ur was a major Sumerian city-state located in Mesopotamia, marked today by Tell el-Muqayyar in southern Iraq. It was founded circa 3800 BCE, and was recorded in written history from the 26th century BCE. Its patron god was Nanna, the moon god, and the city's name literally means "the abode of Nanna."
Cuneiform tablets show that Ur was, during the third millennium BCE, a highly centralized, wealthy, bureaucratic state. The discovery of the Royal Tombs, dating from about the 25th century BCE, showed that the area had luxury items made out of precious metals and semi-precious stones, which would have required importation. Some estimate that Ur was the largest city in the world from 2030-1980 BCE, with approximately 65,000 people.

The Ziggurat of Ur
This temple was built in the 21st century BCE, during the reign of Ur-Nammu, and was reconstructed in the 6th century BCE by Nabonidus, the last king of Babylon. The ruins, which cover an area of 3,900 feet by 2,600 feet, were uncovered in the 1930s. It was part of a temple complex that served as an administrative center for the city of Ur, and was dedicated to Nanna, the moon god.

Control of Ur
Between the 24th and 22nd century BCE, Ur was controlled by Sargon the Great, of the Akkadian Empire. After the fall of this empire, Ur was ruled by the barbarian Gutians, until King Ur-Nammu came to power, circa 2047 - 2030 BCE (the Third Dynasty of Ur). Advances during this time included the building of temples, like the Ziggurat, better agricultural irrigation, and a code of laws, called the Code of Ur-Nammu, which preceded the Code of Hammurabi by 300 years.
Shulgi succeeded Ur-Nammu, and was able to increase Ur's power by creating a highly centralized bureaucratic state. Shulgi, who eventually declared himself a god, ruled from 2029-1982 BCE, and was well-known for at least two thousand years after.
Three more kings, Amar-Sin, Shu0Sin and Ibbi-Sin, ruled Ur before it fell to the Elamites in 1940 BCE. Although Ur lost its political power, it remained economically important. It was ruled by the first dynasty of Babylonia, then part of the Sealand Dynasty, then by the Kassites before falling to the Assyrian Empire from the 10th-7th century BE. After the 7th century BCE, it was ruled by the Chaldean Dynasty of Babylon. It began its final decline around 550 BCE, and was uninhabited by 500 BE. The final decline was likely due to drought, changing river patterns and the silting of the Persian Gulf.
