This thesis intends to establish whether and to what degree possible explanations for the Visegrad Group´s response to the 2015-2016 migration crisis can be provided by Postfunctionalism and Intergovernmentalism. The purpose of this study is not to explicitly test the two theories but to use them as tools to better understand the case under analysis, by applying a non-competitive approach. Based on the elaboration of 21 official statements released by the Visegrad Group between 2015-2016, findings show that both theories could (partially) confirmed my initial hypotheses. I conclude that security matters (as Intergovernmentalist suggests) consisted in the lion´s share in the statements, while economy matters (as also suggested by Intergovernmentalism) did not. When it comes to identity matters (as Postfunctionalism suggests), I conclude that those were used in connection to security matters, with the aim of forging a common European response to the crisis and to justify the partisan reaction of the Visegrad Group.
