The city of Kolkata was known as a city of processions and demonstrations until the 'Spring Thunder' crashed over Naxalbari in 1967. Since then, this historic city-shot down many a time-witnessed a saga of heroic struggles, undying revolutionary optimism and self-sacrifice. Inspired by Mao Tsetung Thought and Charu Mazumdar, radical youth, students and workers rebelled against reaction to 'make the '70s the decade of Liberation' in a way never seen before or after.
