Decommissioning in Northern Ireland was a process in the Belfast Agreement as part of the Northern Ireland peace process. Under the Belfast Agreement, all paramilitary groups fighting in the Troubles would decommission. Decommissioning was a defining issue in the effort to negotiate peace in Northern Ireland.
The Belfast Agreement, or Good Friday Agreement, was signed in Belfast on 10 April 1998 (Good Friday) by the British and Irish governments and endorsed by most Northern Ireland political parties.
It contained provisions for a government involving both Catholics and Protestants, whose traditional aspirations, expressed as nationalism on one side and unionism on the other, had often clashed over the years. The Agreement recognised the legitimacy of both aspirations. One of the provisions of the Agreement was that the parties agree to collectively use their influence to achieve decommissioning within two years, by May 2000.
The Independent International Commission on Decommissioning (IICD) was established to oversee the decommissioning. Its objective was to facilitate the decommissioning of firearms, ammunition and explosives.
Into late 2001, the Provisional Irish Republican Army (IRA) was reluctant to disarm. The IRA refused to disarm because they said that the British government had reneged on its side of the bargain, by watering down the reforms of the Royal Ulster Constabulary proposed by the Patten Commission, and by failing to pull troops out of Northern Ireland.
