This essay has the ambition to examine and compare Croatia’s and Bosnia and Herzegovina’s development towards a consolidated democracy. By applying Linz & Stepen’s theory on how to consolidate a democracy and put focus on political society, behavioral patterns, attitude and constitutional structure the purpose is to find similarities and differences between Bosnia and Croatia within this field. The focus of this study is to compare two similar countries that have developed in very different ways. By applying the theory and a comparative method the purpose is to examine why two so similar countries with so much in common have developed in so different ways? In order to better answer the question there are two part questions and these are: What difficulties, concerning consolidation of democracy, have Croatia and Bosnia faced since the democratic transition in the beginning of the 1990s? What similarities and differences in the area of democratic consolidation (with focus on political society, behavioral patterns, attitude and constitutional structure) are there between the two countries? As the analysis shows, the main reason why these two countries differ so much is that Bosnia is a divided country with different nationalities and each nationality only wants to realize its own interest and does not care about what is best for the country as an entity. However, Croatia has recently realized that democracy is the best for the country and its development.
