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 The latter were withdrawn soon afterwards upon the establishment of the Provisional Government, but the former continued to issue revenue stamps until the late 20th century.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.

The Northern Ireland riots of August 1969 marked the beginning of the Troubles. In Belfast, Catholic Irish nationalists clashed with Protestant Ulster loyalists and the mainly-Protestant Royal Ulster Constabulary (RUC), Northern Ireland’s police force. Hundreds of Catholic homes and businesses were burnt out and more than 1,000 families, mostly Catholics, were forced to flee. The rioting ended with Operation Banner, the deployment of British troops. In December 1969, the IRA split into the 'Official' IRA and 'Provisional' IRA, with the 'Provisionals' promising to defend Catholic areas.
