The transition of Turkey's multi-party system with regard to medium-sized state and axis country concepts

After 1945, the existence of a bipolar system in the international system caused many developments and other countries that wanted to be included in one of these two poles determined different policies. One of these countries is Turkey. Turkey has joined one of these two poles in order to exist in the international system and be protected from threats. The reason for this is that Turkey is a Medium-Sized State. The pole that Turkey is included in is the United States of America (USA), a Western Bloc country. The USA, on the other hand, chose Turkey, an Axis country, in order to take a more effective position against its enemy, the Union of Soviet Socialist Republics (USSR). In addition, Turkey's perception of national security problems from the USSR is one of the factors that pushes Turkey to the USA bloc. In this thesis, the systemic and political developments after 1945, which are the biggest reason for Turkey's transition to a multi-party system, will be evaluated. This evaluation is shaped around the concepts of Medium-Sized State, Axis Country and National Security. The issue claimed in this thesis is that since Turkey is a medium-sized state; it was not kept in the multi-party system in order not to be alone in the newly formed international system and in terms of the threats it perceived.
