History

Historical Context

The 1998 Good Friday Agreement, signed on 10 April 1998 by British PM Tony Blair, Irish Taoiseach Bertie Ahern and US President Bill Clinton, ended three decades of Troubles and won 71 % support in the May referendum. Building on that power-sharing framework, Sinn Féin, the SDLP, the SNP and Plaid Cymru signed a Cardiff memorandum in 2024 to deepen North-South cooperation.
