Welcome to 'Benelux Decoded', the series where we take a closer look at the Benelux Union and its unique role in Europe.
Did you know that the Benelux is often described as a laboratory for the European Union? Through pioneering cross-border projects, Belgium, the Netherlands, and Luxembourg have repeatedly tested ideas that later inspired European integration on a wider scale.
This special role is even explicitly recognised in EU law. Article 350 of the Treaty on the Functioning of the European Union allows the Benelux countries to pursue cooperation that goes further than existing EU rules. In other words: the Benelux is the only regional partnership within the EU with a treaty-based mandate to act as a frontrunner for deeper integration.
One of the clearest examples is the free movement of people. Long before open borders became a European reality, the Benelux countries already understood the importance of seamless cross-border mobility. Together with France and Germany, they helped lay the foundations for the Schengen Agreement in 1985.
The idea is simple but powerful: if cooperation works within the Benelux, it can gradually be expanded and eventually adopted at the European level. In that sense, the Benelux has not only shaped regional cooperation — it has helped shape Europe itself.
