Bosnia and Herzegovina (BiH) is a multiethnic country with a dysfunctional and most complex political system in Europe. The current constitution and political system of BiH was created as a result of the Dayton Peace Agreement, whose primary goal was to end the war. The system which was created consists of too many levels of governance shaped along ethnic lines. At the state level, progress is not possible without the consent of all three constituent peoples (bosnian Serbs, Bosniaks, bosnian Croats), which results in frequent political blockades. The current system prevents the country's progress towards Euro-Atlantic integration and slows down the country's economic development, which affects the growing departure of young citizens and entire families abroad. None of the three constituent nations accepts the current Dayton constitution, which is one of many signs , which shows us that radical changes in the political system are needed. The aim of this paper is to present various forms of westerm democracies that are characteristic for multiethnic countries. Political systems in multiethnic countries such as Belgium, Switzerland, Canada and their models of democracy (federalism, cantonization, consociational democracy) are analyzed and presented as possible solutions for reorganization BiH. The purpose of my thesis is primarily to analyze the positive political solutions of the listed relevant multiethnic countries and to examine the possibilities of their use in the political system of BiH.
