Revenue stamps of the United Kingdom
When Ireland was partitioned into Northern Ireland and Southern Ireland in 1921, separate revenue stamps were issued for both entities. Southern Ireland stamps saw little use since that political entity was quickly superseded by the Provisional Government of Ireland and later the Irish Free State (both of which applied overprints on various British and Irish revenue stamps). However, Northern Ireland continued to use separate revenue stamps until the 1980s. Northern Irish revenues include Civil Service, Dog Licence, Excise and National Insurance stamps, among many others.
Literature of Northern Ireland
The year 1922 marked a significant change in the relationship between Britain and Ireland, with the setting up of the Irish Free State in the predominantly Catholic South, while the predominantly Protestant Northern Ireland remained part of the United Kingdom. The outbreak of The Troubles in the 1960s provided a theme for writers; some were engaged in the social and political background, others reacted against the tensions by looking at nature.
