The Counties Of Ireland

Please be aware that for the purposes of locational categories, i.e. those defined as places, ALL are categorised under Ireland, Places. This includes all place names, cemeteries, churches, schools, universities, etc.
The idea of counties was first introduced to Ireland following the Anglo-Norman invasion in the twelfth century. At that time 12 counties were defined in Leinster and Munster. From that time until the mid sixteenth century county borders were not well defined reflecting the weakness of English control during that period. During the reign of Elizabeth 1 the counties o f, Longford, Clare, Galway, Sligo, Mayo, Roscommon, Leitrim, Armagh, Monaghan (1585), Tyrone, Derry , Donegal, Fermanagh (1585), and Cavan were formed. But still the county borders were not very clearly set out. However, improvements in mapping gradually resulted in the counties as we know them today. Wicklow, surveyed and destinguished into a county in 1606, was the last county to be formed
In Ireland, usage of the word county nearly always comes before rather than after the county name; thus "County Clare" in Ireland as opposed to "Clare County" in Michigan, United States. The former "King's County" and "Queen's County" were exceptions; these are now County Offaly and County Laois, respectively. The abbreviation Co. is used, as in "Co. Clare"
