The Pahlavi regime collapsed following widespread uprisings in 1978 and 1979. The Islamic Revolution dissolved the SAVAK and replaced it with the SAVAMA. It was run after the revolution, according to U.S. sources and persian exile sources in the US and in Paris, by Gen. Hossein Fardoust, who was deputy chief of SAVAK under Mohammad Reza’s reign, and a friend from boyhood of the deposed monarch.
