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 In 1923, at a time when the home nations had withdrawn from FIFA, the FAI was recognised by FIFA as the governing body of the Irish Free State on the condition that it changed its name to the Football Association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.
Northern Ireland
As a consequence of the worsening security situation, autonomous regional government for Northern Ireland was suspended in 1972. Alongside the violence, there was a political deadlock between the major political parties in Northern Ireland, including those who condemned violence, over the future status of Northern Ireland and the form of government there should be within Northern Ireland. In 1973, Northern Ireland held a referendum to determine if it should remain in the United Kingdom, or be part of a united Ireland. The vote went heavily in favour (98.9%) of maintaining the status quo. Approximately 57.5% of the total electorate voted in support, but only 1% of Catholics voted following a boycott organised by the Social Democratic and Labour Party (SDLP).
