With the coming to power of the Justice and Development Party (AKP), led by its leader Recep Tayyip Erdogan, Turkish Muslim nationalism, a new national ideology promoted by the AKP, laid the foundations for a new Turkey and new Turks. Yeni Turkiye Yolunda (Towards a new Turkey) is the slogan used by the Erdogan's party to support a more nationalist Turkey intertwined with its Ottoman and Islamic heritage. In this paper, I put forward the claim that a number of State-sponsored institutions, including new national museums, play a relevant role in shaping this new Turkey. The aim is to investigate how museums operate as instruments of national identity building by exhibiting a fictitious national past. The case study of the Kabatepe Simulation Centre and Museum will serve this purpose. By interviewing politicians, bureaucrats, and historians, I have researched the links between a ruling class that supports Turkish Muslim nationalism, and new public museums, which exhibits it.
