The Anglo-Irish Agreement is an agreement between the British and Irish governments. The agreement was committed with the various institutions defined in the multi-party agreement. It also sets out the position agreed by the two governments on the current and future status of Northern Ireland. The Good Friday Agreement, also known as the Belfast Agreement, was signed on Good Friday on 10 April 1998. It consists of two closely linked agreements, the Anglo-Irish Agreement and the Multi-Party Agreement. It led to the creation of a decentralised system of government in Northern Ireland and the creation of many new institutions, such as the Northern Ireland Assembly and Executive, the North South South Ministerial Council and the British Irish Council. Brooke also tried to connect northern Ireland`s constitutional parties. He proposed that cross-party discussions should be tackled in three areas: the first to deal with relations within Northern Ireland; the second, which deals with relations between the two parts of Ireland; and the third on the links between the British government and the Irish government. Discussions began in April 1991, but quickly became part of procedural disputes. But the three-part format should be at the center of the Good Friday agreement. In addition to the number of signatories[Note 1], Stefan Wolff identified the following similarities and differences between the themes discussed in the two agreements:[28] The two main political parties of 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. In these circumstances, power-sharing has proved impossible to maintain. Meanwhile, voters in each community began to turn away from moderate parties, and instead support for Sinn Féin and the DUP grew, supplanting the SDLP and UUP. For much of the decade following the Good Friday agreement, decentralization was suspended because the main parties in each community were unable to reach a power-sharing agreement. Progress has been made on decommissioning, which was confirmed in September 2005, but a political agreement has remained thoughtless. Finally, the British and Irish governments held crisis talks in St Andrews in October 2006. There, Sinn Féin finally agreed to accept the PSNI, while the DUP agreed to share power with Sinn Féin.

Finally, in May 2007, a leader of the DUP, Sinn Féin, UUP and SDLP was able to take office. This time, the institutions created under the Good Friday Agreement should be maintained until the current political crisis of January 2017 has led to the collapse of the executive. The Good Friday Agreement (GFA) or the Belfast Agreement (irish: Comhaonté Aoine an Chéasta or Comhaonté Bhéal Feirste; Ulster-Scots: Guid Friday Greeance or Bilfawst Greeance)[1] is a couple of agreements signed on 10 April 1998 that put an end to most of the violence of the Troubles, a political conflict in Northern Ireland that had erupted since the late 1960s. This was an important development in the Northern Ireland peace process in the 1990s. Northern Ireland`s current system of de-decentralized government is based on the agreement.
