"This is the first ever study of the little known anwal community of indo-tibetan border, which has been confined for a long time to hilly, forested and remote areas of Uttarakhand Himalaya. The centuries-old social isolation of the anwals has made their identity undefinable in the broad spectrum of Indian social system. It is an effort to bring forth the anwals--their origin, society, culture and economy--to the notice of academicians, policymakers and even to the common men. It is hoped that the study will be able to determine the criteria and the indices to ascertain the social position of various socially isolated communities in general, and the anwals in particular."
