ABSTRACT The paper examines the interconnections between crisis, war and undocumented migration focusing on the crisis at Evros borderzone, Northeastern Greece, in February/March 2020. It puts forward an analysis of public discourse that posits Greece as “a nation under threat” and reflects on the notion of crisis both as a dimension of the present historical moment and a governmental device for strengthening state power. The paper suggests that crisis and war be understood as parts of a security continuum and that the Evros crisis of 2020 rendered visible the mutual constitution of the processes of illegalization and securitization of migration. Formulated as an open threat for Greece and Europe, undocumented mobility feeds into the (in)security spiral promoting more surveillance, tighter border control and deepening the social hierarchy that positions illegal(ized) migrants at the lowest social strata.
