Leftism in India, 1917-1947 provides a comprehensive account of the Leftist movements in India during the most decisive phase of its struggle for freedom and describes how they interacted with the mainstream of the Indian freedom movement under the leadership of the Indian National Congress, guided by Mohandas Karamchand Gandhi and his ideology of non-violence. This ideology directly opposed those who believed in Marxism-Leninism and, little wonder, their policies clashed at almost every stage of the freedom movement. These clashes gave rise to dramatic developments which are vividly described in this work. Each such development has been highlighted in its proper context, analysed with scholarly objectivity and supported by primary source materials collected not only from the Indian National Archives but also from Berlin, Paris, London, Mexico, Moscow and Tashkent.
