Bordering power Europe? The mobility-bordering nexus in and by the European Union

The EU has been built on the idea that enhanced transnational relations and free movement of persons between Member States have a positive impact on international cooperation and security. However, what we have witnessed in the past decade is a growing pressure to limit mobility, reinvigorated by the Covid-19 pandemic. Calls for a strengthened Schengen area go together with the externalization of European borders and the involvement of third states, but also with the reintroduction of border functions between Member States. Inside the EU free movement has been reduced if not stopped for fear of terrorism, irregular migration or the spread of viruses. Meanwhile, new techniques to govern mobility have emerged, affecting the role and meaning of borders. This article focuses on three dynamics of this process that entail a transformation of sovereignty, territoriality and rights: the externalization of borders, internal rebordering and logistification. The article argues that by focusing on what borders do rather than discussing what borders are, we can observe a more comprehensive transformation of borders within, around and outside the EU, a transformation that goes beyond the Westphalian imaginary and the simplistic alternative between hard and soft borders.
