<p>In the (post–Cold War era), one can see violence, ethnic and religious changes in the Middle East more than any other regions in the world. In the recent years, changes and rises have made this region the central place for ethnic and religious crisis around the world. The present study aims to answer this basic question framed through two theoretical approaches of constructivism and Copenhagen school. That is, what are the most influential reasons for spreading pankurdism in the Kurdish-resident regions in the Middle East? In order to answer this question, the research hypothesis is based on some influential elements including self-governance experience in Iraqi Kurdistan as the heart and the locus for forming the dream of great Kurdistan, appearance and activation of new generation of leaders, Kurdish party and civil actors. It also includes intensification of awareness and ethnic identity-orientation among young Kurdish people, the fragility of the government in Iraq, collapse of authority in Syria and appearance and proceeding of Islamic state of Iraq and Syria (ISIS) forces. In this paper, the research method is analytical-causal explanation. The most important findings of the study is that the combination of reasons cause to make spread of pankurdism in the Kurdish-resident region and their convergence effective. These reasons are the identification among the Kurds as the result of dissatisfactions, humiliation, and suppression during several decades, the successful experience of autonomy in the Kurdish-resident regions, and collapse and fragility of authority in Syria and Iraq. In the near future, such increasing opportunities and convergences of the historical and main identity can prepare the Kurds to put pressure on the governments for autonomy or even their independency.</p>
