Mohandas Gandhi, the most iconic figure of Indian nationalism, remains an inspiration for anti-capitalists and peace activists globally. Seventy years after his death, however, his legacy remains contested: was he a saint, revolutionary, class conciliator, or self-obsessed spiritual zealot? This biography examines his campaigns from South Africa to India to evaluate the successes and failures of Satyagraha and Ahimsa. The contradictions of Gandhi's politics are unpacked through an analysis of the social forces at play in the mass movement around him. Entrusted to liberate the oppressed of India, his key support base were in fact industrialists, landlords and the rich peasantry. Gandhi's moral imperatives often clashed with these vested material interests, as well as with more radical currents to his left. Today, our world is scarred by permanent wars, racist violence, environmental destruction, and economic crisis. Can non-violent resistance win against state and corporate power? This book explores Gandhi's experiments in civil disobedience to assess their relevance for struggles today.
