The two main political parties in the agreement were the Ulster Unionist Party (UUP), led by David Trimble, and the Social Democratic and Labour Party (SDLP), led by John Hume. The two heads of state and government together won the Nobel Peace Prize in 1998. The other parties to the agreement were Sinn Féin, the Alliance Party and the Progressive Unionist Party. The Democratic Unionist Party (DUP), which later became the largest Unionist party, did not support the agreement. When Sinn Féin and loyalist parties entered, they left the talks because republican and loyalist paramilitary weapons had not been decommissioned. And yet, in the elections, Hume, Trimble, Durkan and Nesbitt were not overtaken until five years later in the legislative power they had created and promoted by groups that instead appealed to more tribalist instincts. Their decline has in some ways predicted changes that have recently been observed elsewhere in Europe, when far-right and far-left forces opposed each other outside, advocated the closure of communities and countries, and avoided compromises in favour of ideological purity. Instead of encouraging moderation and reconciliation, the Good Friday agreement has instead pushed the electoral West on both sides of the denominational divide away from the centre and towards the extremes. The agreement brought together republicans and trade unionists after decades of political conflict in Northern Ireland 2. Participants also noted that, as part of this comprehensive political agreement, the two governments committed to proposing or supporting amendments to the Irish Constitution or UK legislation on the constitutional status of Northern Ireland. The agreement reaffirmed its commitment to “mutual respect, civil rights and religious freedoms for all within the Community.” The multi-party agreement recognized “the importance of respect, understanding and tolerance with regard to linguistic diversity,” particularly with regard to the Irish language, Ulster Scots and the languages of other ethnic minorities in Northern Ireland, “all of which are part of the cultural richness of the Island of Ireland.” This is because the Good Friday Agreement has created complex agreements between the various parties. The three areas of action of the pact have created a network of institutions to govern Northern Ireland (Strand One), bring together the heads of state and government in Northern Ireland with those of Ireland (Strand Two or North-South Cooperation) and bring together heads of state and government from across the United Kingdom and Ireland (Beach 3 or East-West).
