The main goal of the present study is to seek whether there is a compatibility between Turkey and the European Union (EU) in meeting the key challenges in the global platform, with a special focus on the international crises. With this purpose, the first part has been allotted to the conceptual and historical background. It began with an effort to define the international crisis (and the concepts derived from it) by presenting a historical development. Then, the factors that provide a parallelism for Turkey's and the EU's reactions to crises have been explored. The last chapter is related to the historical evolution of crisis management in these two polities by according a place to NATO. In the second part, factual compatibility of action between the two actors constituted the main research theme. This effort has been materialized through three chapters. At first, diplomatic initiatives have been exposed. The second area of focus concerned the parallelism and divergences in the operational field. In the last chapter, two cases have been studied because of the particular importance that they have for Turkish foreign policy: Cyprus and Iraq.
