The Sunningdale Agreement was an attempt to establish a power-sharing Northern Ireland Executive and a cross-border Council of Ireland. The agreement was signed by the British and Irish government in Sunningdale, Berkshire, on 9 December 1973. Unionist opposition, violence and a general strike caused the collapse of the agreement in May 1974.
