The central aim of this article is to analyse the manner in which the legal structure of EU citizenship subjectifies Union citizens. I begin by explicating Alexander Somek’s account of individualism as a concept which captures EU citizenship and propose to update his analysis by coining the notion of mobile individualism. By looking at a range of CJEU’s case law on EU citizenship through the lens of the purely internal rule and the transnational character of EU citizenship, I suggest that movement sits at the core of EU citizenship. In order to adequately capture this unique structure of citizenship, we need a concept of individualism which takes movement rather than depoliticisation as its central object of analysis. I propose that the notion of mobile individualism can best capture the subjectivity of a model EU citizen, a citizen who is a-political due to being mobile.
