40 Years of Schengen: A European Success Story Facing New Challenges
The Schengen Agreement, signed on June 14, 1985, in the small Luxembourgish village of Schengen, marked the beginning of a revolutionary era of free movement across Europe. Today, the Schengen area comprises 29 countries, including 25 EU member states and four non-EU nations. This passport-free zone has become a symbol of European integration, fostering economic growth and cultural exchange. However, as it celebrates its 40th anniversary, the Schengen area faces unprecedented challenges, including the reintroduction of border controls and political tensions.
The Birth of Schengen
The Schengen Agreement was signed by representatives from Belgium, Germany, France, Luxembourg, and the Netherlands aboard a boat on the Moselle River. The agreement aimed to eliminate internal border checks, a vision fully realized in 1995. Over the years, the Schengen area expanded, welcoming new members like Croatia in 2023 and Romania and Bulgaria in 2025.
Economic and Social Benefits
The Schengen area has significantly boosted trade and tourism. For instance, Romania and Bulgaria's accession in 2025 has streamlined logistics and reduced costs for businesses. Bulgaria's Prime Minister Nikolay Denkov hailed it as a diplomatic triumph, while Romania's finance minister highlighted its appeal to foreign investors. Similarly, Croatia's tourism sector has flourished since joining, with border queues disappearing during peak seasons.
Challenges and Threats
Despite its successes, the Schengen area is under strain. Several countries, including France, Germany, and Austria, have reintroduced temporary border controls to address migration and security concerns. These measures, while legally permissible, threaten the spirit of Schengen. Luxembourg's Interior Minister Léon Gloden recently warned against "creating borders in people’s minds again."
The Future of Schengen
As the Schengen Museum reopens in Luxembourg, its curator reflects on the changing perceptions of the agreement. While once celebrated, Schengen is now scrutinized for its role in migration and security crises. Yet, its core principles remain vital. The challenge lies in balancing freedom with security, ensuring Schengen continues to thrive for another 40 years.
