Rebordering Europe: external boundaries and integration in the European Union

The crises of the European Union and the geopolitical shifts in its international environment have generated a backlash against the post-Cold War ‘debordering’ of European integration. Whereas integration theories focus almost exclusively on the EU’s internal boundaries and developments, this framework paper conceptualizes and theorizes integration as a process of internal debordering and external rebordering. It sketches the history of European integration in a bordering perspective and proposes general assumptions about the EU’s bordering process. Accordingly, rebordering pressures result from widening boundary gaps at the EU’s external borders, exogenous shocks to cross-border transactions, growing community deficits of debordering, and their politicization. Whether external rebordering succeeds and how it interacts with internal boundary formation, depends on EU-level boundary negotiations and the relative costs and benefits of external vs. internal rebordering.
