The entire eastern India was swept by violence just after India's partition and independence on 15 August 1947. Scores of Hindus had to flee the newly created East Pakistan for India and Muslims fled Assam for East Pakistan. A large number of people lost their lives owing to violence, which resurfaced with more ferocity in 1950. Mazumdar, the only member from the undivided Cachar in the cabinet, along with his cabinet and party colleagues took up the responsibility for the safety of both Hindus and Muslims in Cachar, touring affected areas and arranging camps and rehabilitation for the refugees, organising supplies and security.The Bengali Language Movement of 1960-1961 which was a movement to protest the forceful imposition of Assamese language upon the Bengali-speaking population of Barak valley by the Assam Government is also an important event in the history of Barak Valley.
