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 In 1923, at a time when the home nations had withdrawn from FIFA, the FAI was recognised by FIFA as the governing body of the Irish Free State on the condition that it changed its name to the Football Association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.
Irish people
After the Irish War of Independence (1919–1921) the Anglo-Irish Treaty was signed which led to the formation of the semi-independent Irish Free State (now the independent Republic of Ireland) which consisted of 26 counties in the south and Donegal in the North-West. The remaining six counties in the northeast remained in the United Kingdom as Northern Ireland. It is predominately religion, historical, and political differences that divide the two communities of (nationalism and unionism). Four polls taken between 1989 and 1994 revealed that when asked to state their national identity, over 79% of Northern Irish Protestants replied "British" or "Ulster" with 3% or less replying "Irish", while over 60% of Northern Irish Catholics replied "Irish" with 13% or less replying "British" or "Ulster". A survey in 1999 showed that 72% of Northern Irish Protestants considered themselves "British" and 2% "Irish", with 68% of Northern Irish Catholics considering themselves "Irish" and 9% "British". The survey also revealed that 78% of Protestants and 48% of all respondents felt "Strongly British", while 77% of Catholics and 35% of all respondents felt "Strongly Irish". 51% of Protestants and 33% of all respondents felt "Not at all Irish", while 62% of Catholics and 28% of all respondents felt "Not at all British".
