In this study, the different attitudes of the European Union towards Ukrainian and Syrian refugees in its migration policies were examined. The intellectual infrastructure of these attitudes is analyzed within the framework of international relations theories such as The English School, which emphasizes the phenomenon of international society, Social Constructivism theory which emphasizes the construction of common identity and Securitization theory, which examines the process of making a political phenomenon a security issue. In addition to these approaches, the reasons for the double standard of the European Union in their migration policies are also examined in terms of the framework of geographical proximity. It emphasized to what extent the historical memories of European countries have an impact on their migration policies in the text. The theoretical analysis of the different attitudes of the European Union in the face of basically two similar events examined how these policies evolved into xenophobia and how they are fed by the current xenophobic phenomenon in Western Europe. In conclusion, it can be stated that xenophobia is a socio-psychological phenomenon in Western Europe, and this phenomenon is effective both in the determination of daily populist politics and in the attitudes preferred in the face of refugee policies.
