This thesis embarks on efforts to understand how effective is multiculturalism in addressing ethnic cleavages in post-conflict societies. Kosovo, as a post-socialist and post-war country, is the particular case analyzed in order to understand how multiculturalist policies have in the last fifteen years affected interethnic relations in the country. By embarking on a case study approach, I use two main methods, interviewing and document analysis, as a means of triangulation to reinforce the arguments used in the analysis and interpretation of data. Liberal multiculturalism as elaborated by Kymlicka is the theoretical model which is used continuously to give meaning to the empirical data analyzed. The success of multiculturalism is approached in two respects: first, I look at what went wrong during the implementation of such multicultural policies, namely, the approach of international community in addressing interethnic relations through the introduction of group-rights. Secondly, I look specifically at the elements of liberal multiculturalism and how did they affect interethnic relations for the last fifteen years. The thesis shows a shared blame for the persisting fragility of interethnic relations in Kosovo both to the approach of the international community, as well as to the multiculturalist model itself.
