Social movements primarily take the form of non-institutionalised collective political action which strive for political and/or social change. While India has witnessed many such movements over the centuries, it is only recently that scholars have begun to study them in depth. This thoroughly revised and updated version of a seminal book critically examines and reviews the literature concerning social movements in India from 1857 to the present. In the process he discusses the theoretical issues raised by various scholars while analysing major trends in different movements. In conclusion, he suggests areas for future research.
