After suffering a variety of ill effects under the government of Saddam Hussein (a Sunni), Shi'as in Saddam City claimed a degree of autonomy from the rest of Iraq after the fall of Baghdad in April 2003, with their own police force, clinics, and food distribution.
The city is apparently run by local Shi'a clerics, who claim to take orders from upper-level Shi'a clerics in Najaf. They indicate that it is uncertain whether Saddam City will return to the control of a national civil government if one is established. Following the defeat of Saddam Hussein, it was renamed Sadr City, after Ayatollah Mohammad Sadeq al-Sadr.

Saddam City was also the name given to Kuwait City during the Iraqi occupation of Kuwait.
