Fadayan-e Islam is a Shia fundamentalist group in Iran with a strong activist political and terrorist orientation. The group was founded in 1946, and registered as a political party in 1989. It was founded by a theology student, Navvab Safavi. Safavi sought to purify Islam in Iran by ridding it of 'corrupting individuals' by means of carefully planned assassinations of certain leading intellectual and political figures.
