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.

Historians conclude that although there were influences of European nationalism and philosophies of liberalism. In Bengal at large, through the decades 1860s and 1870s, there arose large numbers of "akhras", or gymnasiums consciously designed along the lines of the Italian Carbonari which drew the youth. These were influenced by the works of Italian nationalist Giuseppe Mazzini and his Young Italy movement. Aurobindo himself studied the revolutionary nationalism of Ireland, France and America. Hem Chandra Das, during his stay in Paris, is also noted to have interacted with European radical nationalists in the city, returning to India an atheist and Marxist.
