History of the Anushilan Samiti
Around 1902, Aurobindo Ghosh arranged for Bannerjee to return to Calcutta to begin organisational work, where he began a gymnasium and a youth society. It was at this time that Bannerjee came in touch with Vibhuti Bhushan Bhattacharya, Sarala Devi Ghoshal and Pramathanath Mitra. In Calcutta, a few clubs and societies were still active at the time. Most notable was a gymnasium in Ballygunge Circular Road run by Sarala Devi herself, a second was an organisation named "Anushilan Samiti" founded by Satish Chandra Basu with the patronage of Pramathanath Mitra. A third one was a youth club called "Attōnnōti Samiti" (Self-improvement society) in central Calcutta.
History of the Anushilan Samiti
Through the twenties and thirties, many Anushilan members began identifying with Communism and leftist ideologies. Former Jugantar leader Narendranath Bhattacharya, now known as M. N. Roy, became an influential member of the Communist International, helping to find the Communist Party of India. Particularly during the mass detentions of the 1930s around the Civil Disobedience Movement, many members were won over to the party. By the end of that decade a number of left-wing parties were competing for the youth of Bengal. Most were aimed at broad-based class warfare, opposed to terrorism in principle. Those who did not join left-wing parties identified more closely with Congress.
Jugantar was formally dissolved in 1938, many former members continued to act together under Surendra Mohan Ghose, who acted as a liaison between other Congress politicians and Aurobindo Ghose in Pondicherry.
