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.
