It was founded in 1960 by Third Force activists led by Khalil Maleki and a number of radical nationalists, most of whom had social democracy leanings and some members with Islamic socialism tendencies. Hossein Malek, Ahmad Sayyed Javadi and Jalal Al-e-Ahmad were among people associated with the group.{{cite book|author=Samih K.
