It had spent the majority of its time in the League of Ireland in the Premier Division, the top tier of league football in the Republic of Ireland, but was expelled in November 2009 when it was discovered there were secondary, unofficial contracts with players. It was reinstated a few weeks later but demoted to the First Division, the second tier. The club are the League of Ireland's only participant from Northern Ireland.

The club, founded in 1928, initially played in the Irish League, the domestic league in Northern Ireland, and won a title in 1964–65. In 1971, security concerns related to the Troubles meant matches could not be played at the Brandywell. The team played home fixtures 30 miles away in Coleraine.
