On the hundredth day of 1998, the Northern Ireland peace talks ended with an historic agreement, dubbed the Belfast, or Good Friday Agreement. The accord was reached after nearly two years of talks and 30 years of conflict. A little more than a month later, on May 22, 1998, this Agreement was approved by voters across the island of Ireland in two referendums.
In Northern Ireland, voters were asked 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 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 December 2, 1999
