Immigration is the expression of a long-term (permanent) or short-term Act of relocation from one place to another within or across national borders. Although the element that mobilized this action has changed over the periods, since 1945 to date, there has not been much change in the geography of the target countries that need to be achieved. Today, Europe is the last point in migration movements that all people want to reach. The development of the European Union (EU) countries in the political-social and economic fields is one of the reasons for this mobility. The fact that EU countries have over time turned to a more comprehensive dimension than economic cooperation has also led to countries meeting in a common denominator in solving the problems they face. The EU has moved to establish common policies due to migration problems. In addition to having their own legislation and practices in particular, the countries of the European Union have generally introduced common regulations and practices. In this study, it is discussed how migration movements targeting European countries affect refugee and migrant policies in the process that has come to the present day with the end of the Second World War. The conflict between the EU's humanitarian security approach and its activities to stop illegal immigrants trying to enter its borders, whose numbers have increased since 2011, has been examined. In order to address these contradictions, the measures taken by the EU to protect the rights and security of both EU citizens and migrants/refugees seeking asylum in EU countries by illegal means were examined and the common migration arrangements were discussed.
