Almost 80 years ago, in the mid 1920’s, the first activities of the communist movement started in a rudimentary form in the region of what now constitutes Bangladesh (which was then a part of British ruled undivided India). Independent centers of communist activity developed almost simultaneously in other parts of India and by revolutionary Indian migrants outside India. Within a few years all these scattered centers were brought together and organized into an all-India based party, the Communist Party of India.
