In remembrance of 09/11. 25 years later

Twenty-five years ago, on 11 September 2001, the world witnessed one of the defining tragedies of the modern era. The attacks in the United States claimed thousands of lives, devastated families and communities, and had consequences that reached far beyond the places directly affected.

We believe that remembering significant moments in history is essential to understanding the world we inhabit today. This anniversary offers an opportunity not only to honour those who lost their lives, but also to reflect on the profound changes that followed.

The events of 11 September transformed international politics and security. Governments around the world reconsidered approaches to terrorism, intelligence-sharing, border controls, aviation security and emergency powers. The years that followed also brought major debates concerning surveillance, privacy, civil liberties, migration and the relationship between individual rights and collective security.

The impact was not limited to law or politics. The attacks influenced international relations, economics, technology, media, transport, public policy and everyday life. They changed the way societies understood security and risk, and shaped institutions and policies that continue to influence the present day.

For our community, which brings together students and researchers from different disciplines and backgrounds, this history is particularly important. Understanding 11 September requires more than examining one perspective. It calls for reflection across law, politics, international relations, history, technology, economics, sociology and many other fields.

It is equally important to remember the human dimension of that day. Behind every number was a person, a family, a colleague, a friend and a community. The tragedy also revealed extraordinary acts of courage, compassion and solidarity from first responders, emergency workers and ordinary people who sought to help others in moments of profound uncertainty.

Twenty-five years later, remembrance remains relevant because history does not simply remain in the past. The decisions made in response to moments of crisis can shape societies for decades. They influence how we understand freedom and security, how institutions exercise power, and how communities respond to fear and uncertainty.

As we mark this anniversary, we remember those whose lives were lost and those whose lives were changed forever. We also reflect on the responsibility of future generations to learn from history, to defend human dignity and fundamental freedoms, and to build societies grounded in peace, justice, resilience and respect.
