The difficulties of sociologists - particularly in Germany - to contribute to the political discussion about 'Nation' and (recent) national movements is suggested do be due to insufficiant theoretical clarity. It is proposed to to define ethnic identity as cultural phenomenon. Political unrest and dangerous movements, however, arise, whenever to be 'ethnic' is associated with state/government in its modern sense. The recent experience of political-cultural hegemony over against socalled minorities' makes requests for ethnic self-determination plausible and necessary.
