History of the Anushilan Samiti: The history of the Anushilan Samiti stretches from its beginning early in the first decade of 1900 to its gradual dissemination into the Congress-led Indian independence movement and into the Communist politics in India in the late 1930s.  The "Samiti" began in the first decade of the 20th century in Calcutta as conglomeration of local youth groups and gyms.  However, its focus was both physical education and proposed moral development of its members.  From its inception it sought to promote what it perceived as Indian values and to focus on Indian sports e.g. "Lathi" and Sword play.  It also encouraged its members to study Indian history as well as those of European liberalism including the French Revolution, Russian Nihilism and Italian unification.  Soon after its inception it became a radical organisation that sought to end British Raj in India through revolutionary violence.  After World War I, it declined steadily as its members identified closely with leftist ideologies and with the Indian National Congress.  It briefly rose to prominence in the late second and third decade, being involved in some notable incidences in Calcutta, Chittagong and in the United Provinces.  The samiti dissolved before the Second World War into the Revolutionary Socialist Party.
