Recently, critical voices have raised concerns that EU member states are unwilling to express solidarity and proclaimed that EU solidarity was dead. Surprisingly, the Schengen Area, as opposed to asylum policies, has been examined only sporadically in this context. Although there is overall agreement that solidarity is a necessary precondition for the functioning of Schengen cooperation, it has multiple meanings. Hence, theoretically drawing on the concept of solidarity and methodologically employing the Discourse Historical Approach (DHA), this study attempts to find out how solidarity is conceptualised in legislative and political discourse on Schengen cooperation. It does so by identifying the argumentation strategies of the main actors. The main findings are that whereas scholars tend to link solidarity to free movement and incoming refugees, legislative and political discourse emphasise external border controls. Indeed, this suggests that Schengen will remain resilient as long as its security is ensured, no matter the reimpositions of internal borders. These are perceived as a remedy to Schengen deficiencies rather than a problem per se. Also, in line with EU legislation, the interstate dimension of solidarity clearly prevails within Schengen.
