The people who were trained by Communist International(Comintern) to propel the communist movement were working on it, more or less, at the same time and intervals and in different ways for the expansion of Communist ideology in India. Comintern made three clusters for it and allotted three separate jobs to them. There was one, which was directed by Lenin himself, under the leadership of MN Roy, for creating communist movement in India by the way of armed revolution. Second group was the one that was responsible for integrating the scattered revolutions, struggles and left organizations of India into one centralized communist party to strengthen it. This was lead by British Communist Rajani Palme Dutt and Harry Pollitt. And third group was the one which was responsible for converting the fight of Congress, which was the biggest proponent and party of Indian Freedom Movement, into a leftist agenda and approach. This was lead by Pandit Jawarlal Nehru. The leaders of all three ideologies were a by-product of Comintern only. The whole book, is a historical and sociological study of development of leftist ideology, it?s implementation and effect, from 1917 to 1964, in a global environment. Since Bolshevism emanated in 1917 in Russia and Indian Communist Party?s split along with the death of Pandit Jawahar Lal Nehru, who was responsible for institutionalizing the communist ideology in country?s policy, happened in 1964, that? why this period has been made the book?s architectural theme. This book is first in the series of 3 books on development and effect of communism in India.
