Leftist Politics in British India: A Case Study of the Muslim Majority Provinces Himayatullah Yaqubi * Abstract The paper is related with the history and political developments of the various organizations and movements that espoused a Marxist, leftist and socialist approach in their policy formulation. The approach is to study the left’s political landscape within the framework of the Muslim majority provinces which comprised Pakistan after 1947. The paper would deal those political groups, parties, organizations and personalities that played significant role in the development of progressive, socialist and non-communal politics during the British rule. Majority of these parties and groups merged together in the post-1947 period to form the National Awami Party (NAP) in July 1957. It is essentially an endeavour to understand the direction of their political orientation in the pre-partition period to better comprehend their position in the post-partition Pakistan. The ranges of the study are much wide in the sense that it covers all the provinces of the present day Pakistan, including former East Pakistan. It would also take up those political figures that were influenced by socialist ideas but, at the same time, worked for the Muslim League to broaden its mass organization.
