Partition of Ireland
Beginning on 21 January 1919 with the Soloheadbeg ambush, through the Irish War of Independence, Irish republicans attempted to bring about the secession of Ireland from the United Kingdom of Great Britain and Ireland. Meanwhile, Irish unionistsmost of whom lived in the northeast of the islandwere just as determined to maintain the Union. The British Government, committed to implementing Home Rule, set up a cabinet committee under the chairmanship of southern unionist Walter Long. The Long Committee recommended the establishment of two devolved administrations, dividing the island into two territories: Northern Ireland and Southern Ireland. This was implemented as the Government of Ireland Act 1920. The act entered into force as a "" on 3 May 1921 and provided that Northern Ireland would consist of the six northeastern counties, while the remainder of the island would form Southern Ireland. It was intended that each jurisdiction would be granted home rule but remain within the United Kingdom. The government of Southern Ireland never functioned: the war for independence continued until the two sides agreed a truce in July 1921, ending with the Anglo-Irish Treaty on 6 December 1921.
Northern Ireland
Unlike England, Scotland and Wales, Northern Ireland has no history of being an independent country or of being a nation in its own right. Some writers describe the United Kingdom as being made up of three countries and one province or point out the difficulties with calling Northern Ireland a country. Authors writing specifically about Northern Ireland dismiss the idea that Northern Ireland is a "country" in general terms, and draw contrasts in this respect with England, Scotland and Wales. Even for the period covering the first 50 years of Northern Ireland's existence, the term "country" is considered inappropriate by some political scientists on the basis that many decisions were still made in London. The absence of a distinct nation of Northern Ireland, separate within the island of Ireland, is also pointed out as being a problem with using the term and is in contrast to England, Scotland, and Wales.
