"Birsa Munda, whose Munda rebellion started with attacks on mission posts in 1899, claimed to have visions after the mode of the Biblical prophets, but told his flock to give up animal sacrifice, witchcraft and intoxication and to wear the sacred thread, all amounting to a kind of self-sanskritization. While such charismatic leaders come and go, the tradition of tribal nativism continues, and the VKA seeks to channel it towards integration into a larger Hindu activism. Gérard Heuzé ... aptly notes that the tribal rebellions of the 19th century, such as the 1830 Kol movement, the 1855 Santal Hoot and the 1899 Birsa rebellion, were incorporated by the Freedom Movement in its vision of a native tradition of struggle against foreign invaders (embodying 'the authentic spirit of the nation'), though in fact, exploitation by native (Hindu and Muslim) landlords and money-lenders had also played a role in provoking the tribals into rebellion."
