The volumes provide records for period 1948 to 1971 and chronologically elucidate the trajectory of the various movements and political struggles that led to the formation of an independent nation state called People's Republic of Bangladesh. These include the 1952 Bengali Language Movement that catalyzed the assertion of Bengali national identity in the region and became a forerunner to Bengali nationalist movements. Bangabandhu Sheikh Mujibur Rahman led the struggle for independence, first through massive populist and civil disobedience movements and later during the Bangladesh Liberation War. Important events cited in the present volumes include the 1954 United Front election victory, 1966 Six Point Movement, 1968 Agartala Conspiracy Case, 1969 mass uprising, 1970 election victory and 1971 Non-Cooperation Movement among others. These are the first ever declassified documents released by the Government of Bangladesh and will serve as an invaluable historical resource in understanding the liberation of Bangladesh. This 6th volume holds records for the period 1960-1961.
