This study examines the securitization of international migration within Czech political discourse, focusing on the 2017 parliamentary elections. The objective is to analyze how relevant political parties framed migration, particularly in the context of the so-called European migration crisis of 2015, as a security threat in their pre-election policy documents. Using the concept of securitization as developed by the Copenhagen School, the study explores the extent to which migration discourse was instrumentalized to strengthen political positions and mobilize voters. The study employs a content analysis of the electoral manifestos of major political parties relevant after the 2017 elections to the Chamber of Deputies of the Parliament of the Czech Republic. The findings indicate that international migration was frequently framed as a security threat. This research thus offers a deeper insight into the political utilization of migration issues in the Czech context and its impact on the formation of security discourse in post-communist Central European states.
