The motivation for this thesis has been based on the desire to conduct a contemporary study of securitization in the European Union's migration discourse. This takes into account the extraordinary circumstance of a war in the EU's close proximity and the unique approach the EU has shown towards the people fleeing the war, which seems to differ from the approach observed in research so far. The purpose of this study is to investigate whether the EU presents a securitized migration discourse by examining its discursive presentation of migration and how this presentation relates to securitization. The study is based on the migration discourse presented by the European Council, the European Parliament and the European Commission on the institutions' official websites. The study has been conducted as a qualitative discourse analysis using Carol Bacchi's WPR approach, with the Copenhagen School's securitization theory as the study's theoretical framework. By critically examining the problem definitions, premises and silences in the discourse, the result has shown that the EU mainly presents a securitized migration discourse, which, however, shifts in relation to the referent object of the discourse, i.e. whose security is in question.
