Overview
Traditionally, Ireland has been identified as containing four (4) provinces: Ulster, Connacht (formerly known as Connaught), Munster, and Leinster. Today, the island of Ireland is split between the Republic of Ireland and the constituent country of Northern Ireland within the United Kingdom. The counties within the United Kingdom are the Counties Antrim, Armagh, Down, Fermanagh, Londonderry, and Tyrone.
Traditional Provinces
Within the island of Ireland, the four traditional Irish provinces have been Ulster in the north, Leinster in the east, Munster in the south, and Connacht in the west. Today, each of the counties of Ulster are considered Northern Ireland, with the exceptions of Counties Donegal, Cavan, and Monaghan, all of which are in the Republic of Ireland.
Ulster
Within the traditional Province of Ulster, the nine Irish counties mentioned above—Antrim, Armagh, Cavan, Donegal, Down, Fermanagh, Londonderry, Monaghan, and Tyrone—have been included.
Connacht
Formerly known as Connaught, the traditional Province of Connacht contains Counties Mayo, Sligo, Leitrim, Roscommon, and Galway. Each county is located to the southwest of the general area of Ulster and is representative of the western side of the island.
Munster
The southernmost portion of the island of Ireland has been represented by the Province of Munster, home to the Counties Kerry, Clare, Limerick, Cork, Tipperary, and Waterford. County Cork in particular is one of the more populated counties in all of Ireland to this day.
Leinster
Home to the national capital of the Republic of Ireland, Dublin, the Province of Leinster is on the eastern side of the island of Ireland and contains Counties Kilkenny, Wexford, Carlow, Wicklow, Laois, Kildare, Dublin, Offaly, Westmeath, Longford, Westmeath, and Louth.
