Prior to 1922 the island of Ireland was one country, comprised of thirty-two counties within the four provinces of Connaught, Leinster, Munster and Ulster.
Today the island is divided into two countries:
- the Republic of Ireland, also known as Eire, made up of twenty-six counties
- Northern Ireland, a constituent part of the United Kingdom, made up of six of the counties of the Province of Ulster.
For further historic information, see Counties of Ireland.
