The communal riots of 1947 have been the subject of literature, films and scholarly research. Yet, despite scores of works on the subject, there was still a need for an objective and scholarly account of the way they happened in undivided Punjab. This need has been filled by Dr. Ishtiaq Ahmed who was already well-known in scholarly circles for his work on social science issues in the Asian context (State, Nation and Ethnicity in Contemporary South Asia (1998) and an edited book on religion in Asia). But his latest book is so magisterial in its thoroughness and so meticulous in its research that it should establish him as a major historian of contemporary South Asia.
