Name and Early History
In ancient times Leinster was occupied by five major
Fir-Bolg tribes, of which the tribe of Laigin rose to dominance and gave Leinster its name. The Fir Bolg may be related to the
Belgae, but this has not been firmly established. The tribes of Leinster were united by
Úgaine Mor Hugony, The Great, who built the hill-fort of Ailinne
Knochawlin, near
Kilcullen, County Kildare. He is a likely, but uncertain candidate as the first historical King of Laigin (Leinster) in the
7th century BC. The "-ster" of the toponym comes from the Nordic word for state, as the Vikings dominated and held Dublin and
Waterford, among other times for a period of time (around 800 - 1000).
The kingdom of Laigin was re-founded circa 175/185 AD following a period of civil wars in Ireland by the legendary
Cathair Mor.
Finn Mac Cool, or
Fionn mac Cumhaill, was reputed to have built a stronghold at the Bog of Almhainn, in what was then Leinster.
In the fourth and fifth centuries, after
Magnus Maximus left Britain with his legions, leaving a power vacuum, colonists from Laigin settled in North Wales, specifically in
Anglesey,
Carnarvonshire, and
Denbighshire. In Wales some of the Leinster-Irish colonists left their name on the
Llŷn peninsula, which derives its name from Laigin.
By the eighth century, Laigin , had split into two dynasties:
Northern Leinster dynasty: Murchad mac Brain (d. 727), King of
Uí Dúnlainge, and joint leader of the Laigin
Southern Leinster dynasty:
Áed mac Colggen (d. 738), King of
Uí Cheinnselaig, and joint leader of the Laigin
After the death of the last Kildare-based King of Laigin, Murchad Mac Dunlainge in 1042, the Kingship of Leinster reverted to the
Uí Cheinnselaig sept based in the south east (southern dynasty) which comprise the later
Kings of Leinster.
Some contend it was named after a powerful Welsh colony, meaning Land of the men of the Llyn Peninsula
[1][2].
Borders of Leinster
Today, made of twelve counties, it encompasses the old province of
Mide (mostly now in modern-day County Meath and County Westmeath). Also in it are County Longford and the
Annally and
Lusmagh parishes of County Offaly, formerly of
Connacht, and
County Louth, formerly of
Ulster. The borders were redrawn by Cromwell for administration and military reasons. The last major boundary changes occurred with the formation of County Wicklow (1603-1606), from lands in the north of Carlow (which previously extended to the sea) and most of southern Dublin.
Later minor changes dealt with "islands" of one county in another. By the late 18th century, Leinster looked as shown below.
