Ingenieros participated in the revolutionary struggle from his early youth and was one of the founders (1896) and leaders of the Socialist Party of Argentina. He broke with the reformist leadership of the party in 1913 and took a revolutionary Marxist stand. He enthusiastically welcomed the October Revolution and took part in solidarity demonstrations in support of Soviet Russia. He appreciated the essence of the events in Russia and popularized the ideas of the October Revolution and of Soviet power in his writings. Ingenieros exposed American imperialism as the chief enemy of the peoples of Latin America.
