Especially after 2015, it is possible to see references to the security of the EU and its member states caused by the migration crisis. To observe, this thesis evaluated how the migration into the EU has been securitized in Eurojust discourse between 2010 and 2019. By taking the speech act of the Copenhagen School as the basis, critical discourse analysis is conducted by using documents/publications of Eurojust. As a result of the analysis, it is found that in the period of 2010 and 2014, securitization of migration is not discursively framed. However, after 2015, discourse on securitization of migration can be seen in the documents of Eurojust.Show less
