In the anthropological and sociological studies of India the terms 'tr
ibe' and 'caste', have been in use for almost two hundred years. The r
elated notions of 'tribalism' and 'casteism' were brought in to replac
e a static (structural) by a dynamic (organizational, processual) appr
oach. Since the 1970s, 'ethnic group' and 'ethnicity' have gained curr
ency. After defining the terms, three cases of ethnicity are examined,
namely East Bengali Muslim, Punjabi Sikh and Kashmiri Muslim. It is a
rgued that, while the first is a success story, the second seems more
like a retreat at present, and the third is at best nascent. The reaso
ns for this difference are explored. Ethnicity, it is argued, is not o
nly characterization of identity, but also a set of strategies to esta
blish a new state. This objective is opposed by competing ethnic group
s and the existing state. Ethnic movements therefore involve violence
and their outcome is dependent upon a variety of factors and therefore
contingent.
