This book is an academic attempt of the author to present cultural features of Indian tribes, developmental efforts made by the Government to bring them in mainstream and socio-cultural changes which have occurred in different periods of time making them dynamic and progressive. The book is divided into twenty chapters dealing with the tribals of India. As we know that Indian tribals are found in every geographical region of India such as north-eastern Indian region, north-western Indian region, central Indian region, western Indian region and southern Indian region. Therefore, region-wise cultural practices have been presented in the book describing their social, economic, political, religious, ritualistic, village, polyandrous, polygenous, movements, forest life, women and tribal identity. Changing models of tribal development, welfare programmes and developmental programmes launched by the Government have also found significant place in the book. Processes of socio-cultural changes like Hinduisation, Islamisation, Christianisation, Westernisation, modernisation, secularisation, urbanisation, industrialisation, globalisation, detribalisation, revitalisation, retribalisation and tribalisation have been presented in scientific manner. The book will be of great help to the students of Anthropology, Sociology, History and other social science subjects. It will also be useful to the candidates opting anthropology in different India level or State level competitive examinations and other scholars interested in understanding tribal culture development and change wholistically.
