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.

Even early in his life, during his post-graduate studies, he was actively associated with the Anushilan Samity, an organisation to trigger nationalistic activities. This was founded in Dacca by Barrister P. Mitra on whom Vivekananda made an indelible impact. Later on, this organisation was transferred to Calcutta.
