The Anglo-Irish Agreement was signed on November 15, 1985, at Hillsborough Castle by British Prime Minister Margaret Thatcher and Irish Taoiseach Garret FitzGerald. This landmark treaty aimed to resolve the conflict in Northern Ireland, known as 'The Troubles'. It granted the Irish government an advisory role in Northern Ireland's affairs, while affirming that Northern Ireland's constitutional status would not change without the consent of its majority. The agreement also sought to establish a devolved government in the region, marking a significant step in Anglo-Irish relations and the peace process, despite initial strong opposition from unionists.
