Counties of Ireland

The island of Ireland has 32 counties, with Northern Ireland and the Republic of Ireland being nicknamed respectively the six counties and the twenty-six counties. The counties are subdivisions of the ancient Provinces of Ireland, made up, in general, from smaller territories. While the provinces have existed in some form for many centuries, the counties developed under the Anglo-Norman and British administrations, with the first counties formed in the century after Strongbow's arrival and the last, Wicklow, finally formalised in 1606.
