The Ramadan Revolution, also referred to as the 8 February Revolution and the February 1963 coup d'état in Iraq, was a military coup by the Iraqi branch of the Ba'ath Party which overthrew the prime minister of Iraq, Abdul-Karim Qasim in 1963. It took place between 8 and 10 February 1963. Qasim's former deputy, Abdul Salam Arif, who was not a Ba'athist, was given the largely ceremonial title of president, while prominent Ba'athist general Ahmed Hassan al-Bakr was named prime minister. The most powerful leader of the new government was the secretary general of the Iraqi Ba'ath Party, Ali Salih al-Sa'di, who controlled the National Guard militia and organized a massacre of hundreds—if not thousands—of suspected communists and other dissidents following the coup.
