Abstract
How can anagreement between ethnic diversity and political integration be reached? When is the decision of a group justified? In order to analyse these questions, we will compare the situation of minorities in a clearly defined territory with that of immigrant minorities. Moreover, the necessity for recognition can be justified and as a result the need to live in accordance with cultural and linguistic peculiarities. Central for the desire for recognition is that a determinated self claims the right to determinate her own political, economic and/or cultural matters for herself. This gives equal chances and thus equal treatment to all people. Self-determination can develop to the aspiration of secession, which is accompanied by conflicts. An open theory of selfdetermination shows new perspectives for conflict regulation.
