The Good Friday Agreement (Comhaontú Aoine an Chéasta), lesser known as the Belfast Agreement (Comhaontú Bhéal Feirste), and, more rarely, as the Stormont Agreement was a major political development in the Northern Ireland peace process. It was signed in Belfast on 10 April 1998 (Good Friday) by the British and Irish governments and endorsed by most Northern Ireland political parties. The concord was endorsed by the voters of Northern Ireland and Ireland in separate referenda on 23 May 1998. The Democratic Unionist Party (DUP) was the only large party that opposed the Agreement.
