B.R. Ambedkar's 'Annihilation of Caste' is one of the most important, yet neglected, works of political writing from India. Written in 1936, it is an audacious denunciation of Hinduism and its caste system. Ambedkar - a figure like W.E.B. Du Bois - offers a scholarly critique of Hindu scriptures, scriptures that sanction a rigidly hierarchical and iniquitous social system. The world's best-known Hindu, Mahatma Gandhi, responded publicly to the provocation. The hatchet was never buried.
