Partition of Ireland
The partition of Ireland () divided the island of Ireland into two distinct jurisdictions, Northern Ireland and Southern Ireland. It took place on 3 May 1921 under the Government of Ireland Act 1920. Today the former is still known as Northern Ireland and forms part of the United Kingdom, while the latter is now a sovereign state also named Ireland and sometimes called the Republic of Ireland.
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.
