Derry City F.C.
The border has divided association football teams since 1921. The Irish Football Association (the I.F.A.) oversees the sport in N.I., while the Football Association of Ireland (the F.A.I.) oversees the sport in the Republic. As a result, separate international teams are fielded and separate championships take place (Irish Football League in Northern Ireland, League of Ireland in the rest of Ulster and Ireland). Anomalously, Derry City F.C. has played in the League of Ireland since 1985 due to crowd trouble at some of their Irish League matches prior to this. The other major Ulster team in the League of Ireland is Finn Harps of Ballybofey, County Donegal. When Derry City F.C. and Finn Harps play against each other, the game is usually referred to as a 'North-West Derby'. There have been cup competitions between I.F.A. and F.A.I. clubs, most recently the Setanta Sports Cup.
