The research objective is to reveal the influence of migration processes on interethnic relations and opportunities for achieving civil peace and inter-ethnic stability in multinational states. The leading method is analysis and generalization of sociological data. As a result, the attributes of a common citizens’ identity – the common state, the common history and territory, language and culture – have the consolidating potential in the respondents’ opinion. In conclusion, the creation of effective mechanisms for withdrawal of inter-ethnic tensions and for increasing confidence in the authorities presupposes painstaking work and consists of activities that may seem small in terms of Big Politics.
