The problem of regional underdevelopment, particularly in tribal India, has long been recognized and more than one political party has campaigned on this issue. The Indian constitution and state and central government development plans have included special clauses aimed at assisting those groups, the tribals or adivasis, who are most affected by the problem. Reports have been commissioned and investigations conducted, but rarely have these ended in constructive or relevant action. The work of anthropologists over a number of generations since the 1920s has perhaps done most to tell us of the real depth of the problem as it has affected central India. Foremost amongst them was W. V. Grigson, the aboriginal tribes enquiry officer of the government of the Central Provinces and Berar, whose 1944 report stands as the most comprehensive study available of the condition of the tribal peoples of this region at the end of the colonial period.
