The aim of the article is the analysis of the genesis and contemporary content of the multiculturalism policy, implemented in European countries. The authors also consider the attitude of the European states to the increasing migrants flow. The attention is focused on the theoretical and practical differences in the understanding of the concept of "multiculturalism". Additionally, the analysis of the successful experience in implementing the multiculturalism policy from several non-European continents is presented in this article, which can be also applied in Europe. The authors also analyse the strategic mistakes and the reasons why the policy of multiculturalism is considered to be not effective in Europe today. The article is based on the case study, explicitdiagnostic, descriptive and evaluationary approaches, as well as an analysis of the works of various authors, who have been studying ethno-cultural diversity and multicultural societies for a long time, and on the critical discourse analysis of the recent publications in the media, related to the multiculturalism policy in Europe. © 2020 Faculty of European Studies.
