Anushilan Samiti was an organisation that supported revolutionary violence as the means for ending British rule in India. The organisation arose from a conglomeration of local youth groups and gyms in Bengal in 1902. The Anushilan Samiti was established by Parmathanath Mitra. It had two prominent, somewhat independent, arms in East and West Bengal, Dhaka Anushilan Samiti (centred in Dhaka, modern day Bangladesh), and the Jugantar group (centred at Calcutta). From its foundation to its dissolution during the the Samiti challenged British rule in India by engaging in militant nationalism, including bombings, assassinations, and politically-motivated violence. The Samiti collaborated with other revolutionary organisations in India and abroad.
