By the turn of the fourteenth century the territorial extent of the Irish
lordship was at its height. The O'Brien's regained power in northern Munster
(Thomond). The O'Donnell and O'Neill clans were still extant in northern
Ireland. Among the Irish chiefs also included McCarthy (Cork),
O'Connor (Sligo), O'Rourke (Leitrim), O'Reilly (Cavan), MacCartan (Down),
MacMahon (Monaghan), Maguire (Fermanagh), and O'Hanlon (Armagh).
Around the time of the Scottish campaign into Ireland
(1315-1318) headed by Edward and Robert Bruce, earldoms, liberties and
counties began to be created in Ireland. Roger Mortimer held the lordship
of the liberty of Trim in Meath. The head of the Leinster Geraldines, John
fitz Thomas of Offaly, was created earl of Kildare in 1316. John de
Bermingham, the victor at the Battle of Faughart over Edward Bruce, was
created earl of Louth in 1319. In 1328 James Butler was created earl of
Ormond, with jurisdiction over the new liberty of Tipperary. In 1329 the
head of the Munster Geraldines, Maurice fitz Thomas, was made earl of
Desmond with jurisdiction over the new liberty of Kerry.
