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 Southern Ireland stamps saw little use since that political entity was quickly superseded by the Provisional Government of Ireland and later the Irish Free State (both of which applied overprints on various British and Irish revenue stamps).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.
History of the Orange Institution
The Fourth Home Rule Act was passed as the Government of Ireland Act 1920, the north eastern part of Ulster being partitioned from Southern Ireland as Northern Ireland. This new self-governing entity within the United Kingdom was confirmed under the terms of the Anglo-Irish Treaty of 1921. Southern Ireland became the Irish Free State in December 1922, then, in December 1937, it became Éire. This independent Irish state has been popularly known (in English) as the Republic of Ireland since it left the Commonwealth in April 1949.
