 On Santucho’s initiative, and following shortly after the popular upheaval of 1969 known as "the Cordobazo", the Fifth Congress of the PRT voted in 1970 in favor of the formation of the People's Revolutionary Army (ERP).Although never officially recognized as the armed wing of the party, ERP contained among its members a large group of PRT militants and, more importantly, a number of armed combatants from diverse political and social backgrounds.Like the PRT, the organization's political platform was essentially anti-imperialist and anti-capitalist, with the socialist program of the PRT front-and-center.
