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.
Administrative geography of the United Kingdom
Northern Ireland was the first part of the British Isles to have a devolved government, under the Government of Ireland Act 1920, and that continued until the Parliament of Northern Ireland was suspended in 1972. After a period of direct rule by the Westminster government and some abortive attempts at reinstating devolved government during the Troubles, the present-day Northern Ireland Assembly was established in 1998, and is currently in operation following a number of periods of suspension. The complex history of Northern Ireland has led to differing views as to its status. The term "Province" is often used by unionist and British commentators to refer to Northern Ireland, but not by nationalists.
