Lieutenant General Nasser Moghadam (1921 – 11 April 1979) was the fourth and last chief of SAVAK (6 June 1978 – 12 February 1979). He succeeded General Nematollah Nassiri, who was arrested by the Shah's order in 1978. Moghadam was executed under Ayatollah Khomeini's order, after the Iranian Revolution along with Nassiri and Nassiri's predecessor, Hassan Pakravan.
On January 16th of 1979 the shah and his family fled Iran. On the 1st of February, Khomeini returned from exile and personally led the revolutionary process. After three days of fighting against the Shah's imperial guard Khomeini seized control.
In the overthrow of the shah's regime, Iranian leftists — particularly the radical left from the Mojahedin-e Khalq and Fedayeen Iran — have played no less (and directly in Tehran and major) role than the Islamists.
