Starting with the military coup d'etat of September 12, 1980, Turkey had experienced fundamental changes in its political structure, economic system, social strata, cultural patterns, religious expressionism, and foreign policy. With the end of the Cold War ten years after, the world entered a period of historic systemic changes. Along the way, Turkey moved suddenly from a staunchly pro-vvestern isolationist existence in its immediate neighbourhood into a central posture vvith an intention to have an effect across a vast region extending 'from eastern Europe to western China'. This change in Turkey's stance and mentality was due to wider changes experienced within and around Turkey during the 1980s. This paper, employing theoretic and practical explanations, explores Turkey's transformation in domestic and foreign policies during the 1980s and early 1990s, in order to set the stage to the analysis of Turkish foreign policy at the end of the Cold War. It will specifıcally look at the nature of the political regime, socio-economic dynamics, and external environment as factors that brought about change in Turkish foreign policy in the wake of the end of the Cold War.
