The present volume, entitled East Bengal as East Pakistan and Road to Bangladesh, describes the political and economic aspects of East Bengal (East Pakistan) during 1947-1970. The political and economic history of East Pakistan during Pakistan period was the history of deprivation of the East Pakistanis by the West Pakistanis. The deprivation was in the form of national power imbalance, which led to the denial of Bengali participation in the central decision-making process and of the economic disparity in the disfavor of East Pakistan. The regional power imbalance was created by the civil-military bureaucracy dominated by the West Pakistanis, particularly the Punjabis, who had a long tradition of bureaucratic participation, which automatically limited the intermediate Bengali participation in the government. The economic disparity was twisted in the form of public-private investment and the use of foreign aid and surplus trade balance of East Pakistan in West Pakistan and of inter-wing trade. These factors led to the growth of politics of regionalism in East Pakistan, and the elites there were compelled to launch strong mass movements for regional autonomy. Consequently, East Pakistan declared independence on 26 March 1971 and got liberated from Pakistan’s occupation on 16 December of 1971 after nine months of the War of Liberation, and thus emerged independent Bangladesh.
