The war in Bosnia and Herzegovina ended in 1995 and since then the political structure has been shared between the three ethnic groups in the country, Bosniaks, Serbs and Croats. Bosnia and Herzegovina’s constitution is characterized by the Dayton peace agreement which has existed in the country since the war ended. Dayton peace agreement succeeded to create peace between the three groups, but failed to get a stable and growing society. The main purpose with this essay was to find out why Bosnia and Herzegovina are failing to reach a European Union membership. My conclusion is that Bosnia and Herzegovina’s current policy is the same as it was when the Dayton peace agreement was applied in country’s constitution in 1995. Changes need to be done in order that Bosnia and Herzegovina’s political structure should be developed. As it stands now an EU membership is far away for Bosnia and Herzegovina.
