Ion Gavrilă Ogoranu was a member of the fascist paramilitary organization the Iron Guard, who between 1948 and 1955, after the Soviet occupation of Romania and the establishment of the Romanian People's Republic, became the leader of an underground anti-communist paramilitary group in the Făgăraș Mountains.

The Iron Guard was a Romanian militant revolutionary fascist movement and political party founded in 1927 by Corneliu Zelea Codreanu as the Legion of the Archangel Michael or the Legionary Movement. It was strongly anti-democratic, anti-capitalist, anti-communist, and anti-Semitic. It differed from other European right-wing movements of the period due to its spiritual basis, as the Iron Guard was deeply imbued with Romanian Orthodox Christian mysticism.
