Since the 1980s, media assistance is often used as a tool in democratization processes and state building in post-conflict or fragile states. A number of international organizations, governmental, non-governmental, or inter-governmental, foundations and professional organizations are getting involved in assisting media to develop, while sending material and technical support, offering trainings but also getting involved in the establishment of regulatory bodies, and introducing media laws. This method is yet not well researched, and its effectiveness is under the question in academia as well as by practitioners in the field. In this thesis, I explore whether media assistance was an effective tool of democratization and state-building in post-war Bosnia and Herzegovina, a country that became semi-protectorate after the signing of the Dayton Peace Accord. This thesis discuses if the imposition of the rules that regulate the media, can contribute to the process of democratization and state building, and look into how it affected professionalization of the media.The case of Bosnia is particularly indicative since it was one of the first and one of the biggest media assistance efforts, and some of the methods tested here have been transferred to other post-conflict countries, like Kosovo, Afghanistan, Iraq.
