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.
Hindu nationalism
Anushilan Samiti was one of the prominent revolutionary movements in India in the early part of twentieth century. It was started as a cultural society in 1902, by Aurobindo and the followers of Bankim Chandra to propagate the teachings of the Bhagavad Gita. But soon the Samiti had its goal to overthrow the British rule in India. Various branches of the Samiti sprung across India in the guise of suburban fitness clubs but secretly imparted arms training to its members with the implicit aim of using them against the British administration.
