This thesis focuses on the development of strategic culture in Slovenia and Croatia since independence. Croatia and Slovenia are small countries in the Western Balkans. Both countries became independent in 1991 and since then they became important regional actors in the Western Balkans. This thesis traces Slovenia and Croatia's historical position within the former SFR Yugoslavia's defence system. The empirical analysis in the thesis examines official documents of both countries to find basic notions of the strategic culture of Croatia and Slovenia. The thesis' research focuses on finding how both countries' goal of Euro-Atlantic integration influenced the development of their strategic culture. Keywords: Strategic Culture, Slovenia, Croatia
