Revenue stamps of Northern Ireland
Upon the partition of Ireland in 1921, separate revenue stamps began to be issued for both Northern Ireland and Southern Ireland. The latter were withdrawn soon afterwards upon the establishment of the Provisional Government, but the former continued to issue revenue stamps until the late 20th century. The need for separate issues for Northern Ireland came about since taxes raised there were meant to remain in the country. Most Northern Irish revenue stamps were British key types with appropriate inscriptions, but there were a number of different issues as well.
Northern Ireland Executive
The original Northern Ireland Executive was established on 1 January 1974, following the Sunningdale Agreement. It comprised a voluntary coalition between the Ulster Unionist Party, Social Democratic and Labour Party and Alliance Party of Northern Ireland, with the UUP's Brian Faulkner in the position of Chief Executive. It was short-lived, collapsing on 28 May 1974 due to the Ulster Workers' Council strike, and the Troubles continued in the absence of a political settlement.
