Two distinct cases of kin-state relations are examined: that of Russians living in states neighboring Russia and that of Magyars living in states around Hungary. The role of kin-state relations in Europe is studied from a historical perspective and, with reference to Rogers Brubaker's concept of a triadic nexus between nationalizing states, a national minority, and an external homeland. It is argued that the fall of communism – and the fall of several multi-ethnic federations, in particular – revived old territorial conflicts and hostility among national groups both within and between states. The question of kin-state relations is put at the forefront of European minority issues.
