In spite of recent criticisms the concept of ethnicity should be retai
ned in anthropological analysis to designate more or less coherent cul
tural entities. These entities will be fluctuating, of course, due to
their position in a larger social space where women, goods, ideas, and
institutions are exchanged. Ethnicity is not as some have argued, a c
olonial invention, but an incontestable anthropological fact, where id
entity is nurtured by otherness. Ethnicity does not of itself have a p
olitical vocation: traditional African states were more often than not
pluri-ethnic. The 'national' phenomenon, the convergence of the State
and ethnicity is rare in pre-colonial African history. The nation-sta
te is a modern phenomenon, the product of a more or less arbitrary man
ipulation by an elite having a certain number of ethnic traits; a poli
tical re-modelling of collective identity.
