Initially, the front was an umbrella organization for a broad spectrum of forces with nationalist, liberal-democratic, socialist, "bazaari", secular and Islamic tendencies, that mobilized to successfully campaign for the nationalization of the Iranian oil industry. In 1951, the Front formed a government which was deposed by the 1953 Iranian "coup d'état" and subsequently repressed. Members attempted to revive the Front in 1960, 1965 and 1977.
