The free of movement of people is widely seen as one of the cornerstones of European integration. It allows citizens from member states to live and work across borders and is often celebrated as a symbol of a borderless Europe. Yet this freedom has always depended on complex systems of regulation. Workers moving across borders require access to social security, training, housing, and family rights. To deliver these services, national authorities must coordinate with European institutions, employers, trade unions, and welfare organizations. Internal Fortress examines how European freedom of movement was regulated within nation-states between 1950 and 1980. The project asks a fundamental question: did European integration weaken national control over migration, or did it instead reshape and in some cases even strengthen national regulatory systems?
The decades after the Second World War were a formative period. Countries in Western Europe shifted towards a new model of mass immigration, while at the same time rebuilding war-torn economies and expanding welfare. Thus, the rules governing free movement in the European Economic Community (EEC) intersected with a complex range of social and economic priorities in the member states. Governments had to reconcile broad mobility rights with national and local efforts to build up social services and promote full employment, while also balancing migration relationships with states outside the EEC, including many former colonies.
The project uses a mix of public and private archival sources drawn from local, national, and international bodies to understand how this process unfolded in practice. In doing so, it contributes to broader debates about migration governance, the postwar welfare state, and European integration. The project explores how European free movement helped to introduce a more decentralized - and often more conflictual - mode of migration politics. The expected impact is twofold. First, the project helps shift the focus of academic research from the negotiation of formal European rules in Brussels to their practical implementation. Secondly, it provides a valuable reference point for people who are currently active in migration policy, by revealing how today’s broad norms of regional mobility have been constructed over time through a diffuse process organizational tinkering, often far from the border.
