Forty Years of the Schengen Agreement: A Milestone Celebration Amid Mounting Challenges

In June 2025, the European Union commemorates the 40th anniversary of the Schengen Agreement, a historic milestone that revolutionized the concept of freedom of movement across Europe. Signed on June 14, 1985, in the small Luxembourgish town of Schengen, the agreement marked the beginning of the gradual dismantling of internal border controls among participating countries. Four decades later, Schengen remains one of the EU’s most tangible symbols of unity, liberty, and European integration. However, as Europe celebrates this anniversary, the once-unquestionable principle of borderless travel faces growing political, security, and social pressures.

 

The Genesis of Schengen: A Bold European Experiment

The Schengen Agreement was originally signed by five of the ten member states of the European Economic Community (EEC) — Belgium, France, Germany, Luxembourg, and the Netherlands. It set the stage for eliminating internal border checks while reinforcing external border controls. It was not a part of EU law initially but functioned as an intergovernmental agreement among a coalition of willing states. The agreement came into force in 1995 with the implementation of the Schengen acquis and later became part of EU law through the 1997 Treaty of Amsterdam.

Schengen not only allowed people to travel across borders without passports but also fostered economic growth by easing the movement of goods, services, and labor. Today, the Schengen Area includes 29 European countries, covering most EU member states and several non-EU nations such as Norway, Switzerland, Iceland, and Liechtenstein.

 

A Symbol of European Unity and Cooperation

At its heart, the Schengen Agreement symbolizes a deep commitment to European solidarity and cooperation. It has facilitated tourism, cultural exchange, cross-border employment, and transnational infrastructure projects. For many citizens, the ability to move freely across borders without cumbersome checks is an everyday convenience that underscores their European identity.

The economic impact has been substantial. According to the European Commission, Schengen contributes significantly to the EU’s GDP by reducing travel time and transportation costs. It also enhances competitiveness by allowing businesses to operate seamlessly across borders and encouraging intra-EU trade.

 

Recent Expansions and Integration

The Schengen Area continues to evolve. In January 2025, Romania and Bulgaria joined the Schengen Zone with air and sea border checks lifted, marking a long-awaited step toward full integration. Their accession came after years of political negotiations and concerns over border security and rule of law, showcasing the delicate balance between inclusion and scrutiny within the EU.

Croatia, another Balkan country, became a full member of the Schengen Area in January 2023, further consolidating the geographic and political cohesion of the bloc. These expansions demonstrate that the vision of a borderless Europe still holds strong appeal, particularly among countries striving for deeper integration into the EU framework.

 

Current Challenges to Schengen and Freedom of Movement

Despite its many successes, the Schengen Area is under considerable strain. Multiple crises over the past decade have exposed vulnerabilities in the system and reignited nationalistic and protectionist sentiments.

1. Migration and Asylum Pressures
The 2015 refugee crisis was a watershed moment for Schengen. Over a million refugees and migrants, primarily fleeing conflict in Syria, Afghanistan, and Iraq, arrived in the EU, overwhelming border countries and straining asylum systems. Several Schengen states, including Germany, Austria, and Sweden, reintroduced temporary border checks, citing security concerns and the inability to manage the inflow effectively.

Although the migration rate has declined since its peak, asylum applications in the EU remain significant, with continued instability in parts of Africa and the Middle East. The pressure on southern European countries like Greece and Italy has led to calls for a more equitable burden-sharing mechanism, but progress remains slow and contentious.

In response, the EU has attempted to strengthen the external borders through agencies like Frontex, which now plays a central role in coordinating border security. Yet, member states continue to diverge on issues like relocation quotas, asylum reform, and border fencing, creating friction within the Union.

2. Security Threats and Terrorism
The rise of terrorism in Europe — particularly the 2015 and 2016 attacks in Paris, Brussels, and Nice — heightened concerns about the Schengen Zone’s vulnerability to transnational threats. Critics argue that freedom of movement, while valuable, can be exploited by criminals and extremists.

As a result, intelligence-sharing, surveillance, and police cooperation have become more integrated, with databases such as SIS (Schengen Information System) and ETIAS (European Travel Information and Authorization System) playing a crucial role. However, the balance between security and privacy remains a sensitive issue, as does the legitimacy of extended internal border checks, which some claim violate the spirit of Schengen.

3. Pandemics and Public Health
The COVID-19 pandemic presented an unprecedented challenge to Schengen. In early 2020, nearly all member states reimposed internal border controls in an effort to contain the virus, bringing cross-border travel to a near halt. Although these measures were temporary, they highlighted how quickly national governments can act unilaterally during crises, raising questions about the resilience and legal framework of Schengen.

The pandemic also reshaped public opinion on freedom of movement, with many citizens expressing concerns over health risks associated with open borders. While most restrictions have since been lifted, the experience revealed how vulnerable Schengen is to disruption in times of emergency.

4. Rise of Nationalism and Political Fragmentation
Across the EU, rising populist and nationalist movements continue to challenge supranational institutions and policies — including Schengen. Leaders and parties advocating stricter border controls often cite fears over immigration, loss of sovereignty, and cultural erosion.

This trend has complicated EU negotiations on issues such as enlargement, border policy, and asylum reform. It also fosters a climate of mistrust among member states, making it harder to maintain the mutual confidence that underpins the Schengen system.

 

The Path Forward: Reform and Reinforcement

The EU is well aware of the challenges and has launched several initiatives to safeguard and reform Schengen. In 2021, the European Commission unveiled a Schengen Strategy aimed at strengthening internal and external border management, ensuring faster crisis response mechanisms, and promoting greater solidarity among states.

Key pillars of reform include:

• Modernizing border infrastructure and technology, including biometrics and automated checks.
• Clarifying rules for reintroducing internal controls, ensuring they remain exceptional and proportionate.
• Enhancing the role of Frontex, including increased funding and staffing.
• Implementing the New Pact on Migration and Asylum, which seeks to create a more sustainable and fair system for handling migration flows.

However, reforms alone cannot resolve all tensions. The EU must also work to rebuild public trust in Schengen, combat disinformation, and ensure that the benefits of freedom of movement are communicated clearly and equitably across all member states.

 

A Moment of Reflection and Renewal

As the EU marks 40 years since the signing of the Schengen Agreement, it stands at a crossroads. The celebrations provide an opportunity to reflect on the achievements of borderless Europe while acknowledging the complexities of maintaining such an ambitious project in a changing world.

Freedom of movement remains one of the most cherished and impactful rights granted by the EU. For millions of citizens, it symbolizes peace, prosperity, and the shared destiny of European nations. But preserving this freedom requires vigilance, adaptability, and a renewed commitment to solidarity.

 

Conclusion

The Schengen Agreement has transformed Europe in profound and lasting ways. What began as a bold experiment among five nations is now a cornerstone of European identity and integration. As challenges continue to mount — from migration to terrorism to pandemics — the EU must navigate a delicate path between openness and security.

Forty years on, the dream of a borderless Europe is alive, but it is not guaranteed. To keep that dream alive for future generations, Europe must reaffirm its values, reinforce its institutions, and remember that unity, not division, has always been its greatest strength.
