This volume in The New Cambridge History of India looks at the numerous nineteenth-century movements for social and religious change–Christian, Hindu, Muslim, Sikh, and Zoroastrian–that used various forms of religious authority to legitimize their reform programs. Such movements were both indigenous and colonial in their origins, and the author shows how each adapted to the challenge of competing nationalisms as political circumstances changed. The volume considers the overall impact of British rule on the whole sphere of religion, social behavior, and culture.
