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 The latter were withdrawn soon afterwards upon the establishment of the Provisional Government, but the former continued to issue revenue stamps until the late 20th century.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.
National symbols of Ireland, the Republic of Ireland and Northern Ireland
Symbols of Ireland are marks, images, or objects that represent Ireland. Because Ireland was not partitioned until 1922, many of the symbols of Ireland predate the division into Southern Ireland (later Irish Free State and then Ireland) and Northern Ireland.
