Colonial and Post-Colonial Identity Politics in South Asia analyses the colonial and post–colonial documentation and caste classification among Muslims in India, demonstrating that religion negotiated with regional social customs and local social practices whilst at the same time fostering a shared religious belief. The central question addressed in this is book is how different castes assert their identity for classification and how caste encountered colonial documentation. Identifying the colonial context of the documentation of caste among Muslims, and relying on colonial documentation in various census reports, Gazetteers, government or police records, ethnographic studies and travelogues, the author demonstrates the sheer diversity of attempts and caste among Muslims. The book deconstructs how under Colonialism Muslims were categorized into three broad but overlapping categories - Ashraf, Ajlafs and Arzals - and that Muslims were categorized into Asiatic, Non-Asiatic, Foreign, Mixed and Hindustani –Muslim categories. It argues that few colonial theories applied to Muslims. Finally, the author explores post-colonial documentation of castes among Muslims in various Commission reports, particularly in Backward class commission reports and its interplay in the reservation politics of the contemporary period and examines the growth of various Muslim caste organizations in different parts of India and their role in identity politics. Providing a new perspective on the issue of minorities in India, this book will be of interest to scholars of religion, Islam, history, politics and sociology of India.
