On 7 February 1992, twelve states signed the Maastricht Treaty, the foundation treaty of the European Union. As the treaty enters its 30s, what has it achieved? And where do we go from here? Bruegel’s Maria Demertzis talks to Amy Verdun, Professor at the University of Victoria and visiting Professor at Leiden University, and Mathieu Segers, Professor in Contemporary European History at Maastricht University and Europe Chair at Studio Europa Maastricht, starting with their own personal recollection of 1992.
