This work is a case study that has its focus on the Civilizations and the Clash or Alliance of civilization that has been in existent in one time or another throughout the world. In the field of this work, I have prepared a definition chapter and I have explained some terms about my thesis. First of all is the term "civilization" and I will try to write the following question’s answer? What is civilization? The chapter of ‘opponent theories’ in this work is about theories of the opposite side of the "Alliance of Civilization". The first opponent theory is the "end of the world" by Francis Fukuyama and second one is the "Clash of Civilization". The Project of "Alliance of Civilization". Firstly, it is explained as a UNO project; this process started in 2005 by Annan who is the former General-Secretary of UNO. Turkey and Spain organized this project making Spain and Turkey as co-chairs too. However, I also think of ‘alliance’ as having a general meaning. Turkey’s relationship with Middle-East countries like Syria, Iran and Israel- Palestine proves to be an important factor. Turkey wants to join the European Union. I claim that, this condition is an opportunity for both sides.
