Author Ramachandra Guha's Gandhi: The Years That Changed the World, 1914-1948 is the second and concluding volume of the magisterial biography that began with the acclaimed Gandhi Before India, the definitive portrait of the life and work of Mahatma Gandhi. This volume opens with Mohandas Gandhi's arrival in Bombay in January 1915 and takes us through his epic struggles over the next three decades: to deliver India from British rule, to forge harmonious relations between India's Hindu and Muslim populations, to end the pernicious Hindu practice of untouchability, and to develop India's economic and moral self-reliance. We see how in each of these campaigns, Gandhi adapted methods of nonviolence – strikes, marches, fasts – that successfully challenged British authority, religious orthodoxy, social customs, and would influence non-violent, revolutionary movements throughout the world.
