This study will draw attention to the two important historical moments during the Palestinian conflict and will focus how they have been perceived and been debated among the Turkish Islamism. These two important moments to be focused are the 1948 Arab-Israeli War which emerged immediately after the establishment of Israel, and the 1967 Six Days War, which occurred almost 20 years after the first one and lasted only six days. In both wars, the Arabs have been defeated, and the newly established state of Israel got a chance to increase his power in the region and strengthened their policies towards the vulnerable region. Moreover, both wars brought about critical ruptures and renewals within the ideas of nationalism, socialism, and Islamism as the political thought of Arab World. Firstly, in this work, it will be analyzed how these changes are perceived and discussed from the perspective of a different Islamic country which out of the region. In this regard, Turkey is an interesting example with his different political attitudes to the region and more importantly the historical ties and relations with the societies of the region. Then, after mentioning briefly as a matter of the Turkish Foreign policy approaches to these two major wars, I will focus the idea of Islamism that has revealed itself in different forms in both periods and its approaching to these two important wars and aftermath. Although the Palestine-Israel issue has always been occupied an important place in the Islamic thought in Turkey, because of its periodic changes at different eras, Turkish Islamism has ascribed different meanings to the developments in the region over these two wars. In the Turkish Islamic thought, on the one hand, there are some approaches to these developments in the region that have based on more global scale and external outbreaks, on the other hand, there are also approaches in both cases that deal with the attitude of the Arab States and more generally the situation of Muslims in a self-criticism. Finally, in this study, all these debates will be handled through some effective Islamic periodicals such as Sebilürresad, Büyük Doğu, Hilal and İslam as important grounds for discussing the issues of Islamic thought.
