Is it true that does northern ireland have a national football team based on the following text?

The Northern Ireland national football team represents Northern Ireland in international association football. From 1882 to 1921 all of Ireland was represented by a single side, the Ireland national football team, organised by the Irish Football Association (IFA). In 1921, the jurisdiction of the IFA was reduced to Northern Ireland following the secession of clubs in the soon-to-be Irish Free State, although its team remained the national team for all of Ireland until 1950, and used the name Ireland until the 1970s. The Football Association of Ireland (FAI) organises the separate Republic of Ireland national football team.
