Ulster

Ulster, northernmost of the historic provinces of Ireland. Modern Ulster consists of nine counties. Six (Antrim, Armagh, Down, Fermanagh, Derry, and Tyrone) now make up Northern Ireland (see Ireland, Northern), which is often referred to as Ulster; the remaining three (Cavan, Donegal, and Monaghan) are in the Republic of Ireland.
