For the first time ever in history, a Member State decided to leave the EU.

Following the result of a divisive referendum, the United Kingdom triggered Article 50 of the Lisbon Treaty, setting in motion its exit from the EU on 31 January 2020 after 47 years of membership.

This historical moment was epitomised when the UK flag was taken down from outside the Committee of the Regions in Brussels and added to the House of European History’s collection.
