The Good Friday Agreement is accepted in a referendum in Northern Ireland with roughly 75% voting yes.
The Good Friday Agreement (GFA), or Belfast Agreement (Irish: Comhaontú Aoine an Chéasta or Comhaontú Bhéal Feirste; Ulster-Scots: Guid Friday Greeance or Bilfawst Greeance), is a pair of agreements signed on 10 April 1998 that ended most of the violence of the Troubles, a political conflict in Northern Ireland that had ensued since the late 1960s. It was a major development in the Northern Ireland peace process of the 1990s. Northern Ireland's present devolved system of government is based on the agreement. The agreement also created a number of institutions between Northern Ireland and the Republic of Ireland, and between the Republic of Ireland and the United Kingdom.
Issues relating to sovereignty, civil and cultural rights, decommissioning of weapons, demilitarisation, justice and policing were central to the agreement.
The agreement was approved by voters across the island of Ireland in two referendums held on 22 May 1998. In Northern Ireland, voters were asked in the 1998 Northern Ireland Good Friday Agreement referendum whether they supported the multi-party agreement. In the Republic of Ireland, voters were asked whether they would allow the state to sign the agreement and allow necessary constitutional changes (Nineteenth Amendment of the Constitution of Ireland) to facilitate it. The people of both jurisdictions needed to approve the agreement in order to give effect to it.
The British–Irish Agreement came into force on 2 December 1999. The Democratic Unionist Party (DUP) was the only major political group in Northern Ireland to oppose the Good Friday Agreement.
