Northern Ireland national football team
In 1920, Ireland was partitioned into Northern Ireland and Southern Ireland. In 1922, Southern Ireland gained independence as the Irish Free State, later to become a republic under the name of Ireland. Amid these political upheavals, a rival football association, the Football Association of Ireland, emerged in Dublin in 1921 and organised a separate league and international team. In 1923, at a time when the home nations had withdrawn from FIFA, the FAI was recognised by FIFA as the governing body of the Irish Free State on the condition that it changed its name to the Football Association of the Irish Free State. The Irish FA continued to organise its national team on an all-Ireland basis.
Provinces of Ireland
The earliest recorded mention of the major division of Ireland is in the Ulster Cycle of legends, such as the "Táin Bó Cúailnge". The "Táin" is set during the reign of "Conchobar Mac Nessa", king of Ulster, and is believed to have happened in the 1st century. In this period Ireland is said to have been divided into five independent over-kingdoms, or "cuigeadh" whose "rí" (kings) were of equal rank, not subject to a central monarchy. Pseudo-historians called this era "Aimser na Coicedach", which has been translated as: "Time of the Pentarchs"; "Time of the Five Fifths"; and "Time of the provincial kings". It was also described as "the Pentarchy".
