Anushilan Samiti
Anushilan Samiti (Ōnūshīlōn sōmītī, "lit": body-building society) was a Bengali Indian organisation that existed in the first quarter of the twentieth century, and propounded revolutionary violence as the means for ending British rule in India. The organisation arose from a conglomeration of local youth groups and gyms ("Akhara") in Bengal in 1902. It had two prominent, if somewhat independent, arms in East and West Bengal identified as Dhaka Anushilan Samiti centred in Dhaka (modern day Bangladesh), and the Jugantar group (centred at Calcutta) respectively.
Anushilan Samiti
A large portion of the Anushilan movement was attracted to left-wing politics during the 1930s, and those who did not join left-wing parties identified with Congress and the Congress Socialist Party. During the mass detentions of the 1930s surrounding the civil-disobedience movement, many members were won over to the Congress. Jugantar was formally dissolved in 1938; many former members continued to act together under Surendra Mohan Ghose, who was a liaison between other Congress politicians and Aurobindo Ghose in Pondicherry. During the late 1930s, Marxist-leaning members of the Anushilan in the CSP announced the formation of the Revolutionary Socialist Party.
