Muqtada al-Sadr is an Iraqi politician, cleric, and militia leader, best known as the leader of the Sadrist Movement, an Iraqi Islamist nationalist movement. Born and raised in Najaf, Iraq, he is the son of Ayatollah Mohammad Mohammad Sadeq al-Sadr, an important Islamic Shiite figure in Iraq. Following the 2003 U.S. invasion of Iraq, Muqtada tried to inherit his father’s legacy but initially, he failed. Over time he appealed to the young and impoverished Shiite Iraqis and formed Mahdi Army, an armed force. However, over time, Muqtala’s intentions became more political as he became more moderate in his views. His party, the Sadrist Movement, played a big role in the 2005 general elections when he became the ‘kingmaker’ and lent his support to the party of Nouri al-Maliki, who became the Prime Minister of Iraq. Eventually, Muqtada turned his Mahdi militant army to the Peace Companies and in the early 2010s, he upheld his image as a nationalist rather than a religious leader. In the 2018 elections, he formed the SairoonAlliance with the Communist Party of Iraq and other political organizations and performed well in the elections.
