Political history of Sri Aurobindo
Anushilan Samiti was founded as an attempt to organize Bengali youth through a program of physical fitness and spiritual training for a nationalist program. By 1902, Calcutta had three societies working under the umbrella of Anushilan Samity, a society earlier founded by a Calcutta barrister by the name of Pramatha Mitra. These included Mitra's own group, another led by a Bengali lady by the name of Sarala Devi, and a third one led by Aurobindo Ghosh. The Anushilan Samiti had Aurobindo and Deshabandhu Chittaranjan Das as the vice-presidents, Suren Tagore the treasurer. Jatindra Nath Banerjee (Niralamba Swami), Bagha Jatin, Bhupendra Nath Datta (Swami Vivekananda's brother), Barindra Ghosh were among other initial leaders.
By 1905, the work of Aurobindo and his brother Barin Ghosh allowed Anushilan Samity to spread through Bengal.
History of the Anushilan Samiti
However, although sharing some critiques against the leadership of Joseph Stalin and the Comintern, the Anushilan Marxists did not embrace Trotskyism. Buddhadeva Bhattacharya writes in 'Origins of the RSP' that the "rejection of Stalinism did not automatically mean for them [the Anushlian Samiti] acceptance of Trotskyism. Incidentally, the leninist conception of international socialist revolution is different from Trotsky's theory of Permanent Revolution which deduces the necessity of world revolution primarily from the impossibility of the numerically inferior proletariat in a semi-feudal and semi-capitalist peasant country like Russia holding power for any length of time and successfully undertaking the task of socialist construction in hand without the proletariat of the advanced countries outside the Soviet Union coming to power through an extension of sociaist revolution in these countries and coming to the aid of the proletariat of the U.S.S.R."
