The Good Friday Agreement is signed in Northern Ireland.

The Good Friday Agreement (GFA) or Belfast Agreement is a pair of agreements signed on 10 April 1998 that ended most of the violence of the Troubles, an ethnic and national conflict in Northern Ireland since the late 1960s. It was a major development in the Northern Ireland peace process of the 1990s. It is made up of the Multi-Party Agreement between most of Northern Ireland's political parties, and the British–Irish Agreement between the British and Irish governments. Northern Ireland's present devolved system of government is based on the agreement.

April 10 is the 100th day of the year in the Gregorian calendar; 265 days remain until the end of the year.
