Muhammad-Sadiq al-Sadr

Mohammad al-Sadr's son, Muqtada al-Sadr, is currently the leader of the Sadrist movement and bases his legitimacy upon his relationship to his father. He led a guerrilla uprising against Coalition forces and the new Iraqi government as part of the Iraqi Insurgency between 2004 and 2008.

Following the fall of Baghdad, the majority-Shi'a suburb of Revolution City (Saddam City) was unofficially but popularly renamed to Sadr City in his honour. Sadr City was the first part of Baghdad to overthrow the Baath Party in 2003.

Sometime before his death, al-Sadr was informed of Saddam's limited patience with him. In defiance, al-Sadr wore his death shroud to his final Friday sermon to show that the Shi'ites would not be intimidated by Saddam's oppression and that Sadr would preach the truth even if it meant his own death. He was later killed leaving the mosque in the Iraqi city of Najaf along with two of his sons as they drove through the town. Their car was ambushed by men, and both his sons were killed by gunfire while he was severely injured. He died an hour later in the hospital. Shi'as in Iraq, as well as most international observers, suspect the Iraqi Baathist government of being involved in, if not directly responsible for, their murders. Anger at, among other things, the government's involvement in Sadr's death helped spark the 1999 Shia uprising in Iraq.

As his power grew, al-Sadr became more and more involved in politics following the Gulf War, and throughout the 1990s, he openly defied Saddam. He organized the poor Shi'ites of Sadr City, yet another nickname for the impoverished Shi'ite ghetto in Baghdad, against Saddam and the Baath Party. Sadr gained the support of the Shi'ites by reaching out to tribal villages and offering services to them that they would otherwise not have been afforded by Hussein's regime. Saddam began to crack down on the Shi'ite leaders in the late 1990s in an attempt to regain control of Iraq.

Grand Ayatollah Sayyid Muhammad Muhammad-Sadiq al-Sadr (Arabic: محمد محمّد صادق الصدر; 23 March 1943 – 19 February 1999) was a prominent Iraqi Shia marja'. He called for government reform and the release of detained Shia leaders. The growth of his popularity, often referred to as the followers of the Vocal Hawza, also put him in competition with other Shi'a leaders, including Mohammed Baqir al-Hakim who was exiled in Iran.

al-Sadr was born to Muhammad Sadiq al-Sadr (1906–1986), the grandson of Ismail al-Sadr, the patriarch of the Lebanese al-Sadr family and a first cousin of Muhammad Baqir al-Sadr and Amina al-Sadr.
