This master thesis aims at investigating whether and to what extent the European Union contributes to democratic consolidation in Bosnia-Herzegovina within the scope of its integration process. For this purpose, the empirical study is based on Merkels model of democratic consolidation. In order to build upon this model, the basic terms and theories of transformation science were clarified at first. Following this, the demography of the country was addressed. Due to the multiethnic composition of the population, an analysis of the handling of this multiethnicity after the ethnic conflict, and before the engagement of the EU, was performed. In this light, the constitution and the behaviour of the political elite were examined. In order to be able to determine a possible democratisation process, these two factors were also subjected to an evaluation within the frame of the EUs engagement. Analysis showed that the EU has taken measures to weaken the ethnonationalist parties dominant after the conflict and to promote a civic culture. Furthermore, it was shown that the EU seeks to achieve a constitutional reform that would promote the integration process and be supported by the ethnically divided internal powers, which, however, proves to be difficult seeing the prevailing distrust among the ethnicities. Equally, it became clear that EU politics are characterised by inconsistency, short-sightedness, indulgence and passivity: To date there is no tailor-made strategy to integrate Bosnia-Herzegovina into the EU which is also why the EU is helpless in the face of fundamental problems, has to concede even for little progress and fails to profit from the promising integration perspective. In order to promote the democratisation process, the EU would have to overcome its inner dissent as well as its enlargement fatigue and find an individual approach to the country meeting the local conditions.
