When Dermod Mor MacCarthy submitted to King Henry II of England at Cashel in 1171, he was using the diplomacy his ancestors had used for generations. A Gaelic king secured his lands by acknowledging a higher lord. He was not surrendering them; he was placing them under protection. Henry, however, was not a Gaelic king. He took the submission, smiled, and six years later granted MacCarthy's entire kingdom of Desmond to two of his adventurer knights - Robert FitzStephen and Milo de Cogan. The barony of Muskerry East still bears the outline of that confusion. Its name comes from the ancient kingdom of the Muscraige, and the modern administrative boundary runs along the same lines a Gaelic chieftain would have recognised over a thousand years ago.
Muskerry East is one of 24 baronies in County Cork - a unit of land that the Normans introduced after their invasion of Ireland in 1169, mapped on top of an older Gaelic geography that they could neither fully replace nor fully ignore. The barony takes its name from the Muscraige, who descended, according to the pedigrees in the Book of Leinster, from Corc - a son of Cairbre Musc. They were a pre-Eoganacht people, settled in Munster before the sixth century, with petty kingdoms scattered across the province but their core territory in what are now the baronies of Muskerry East and Muskerry West. The chief town today is Ballincollig. The neighbouring baronies are Cork to the east, Duhallow to the north, and Barretts to the northeast. Although baronies have been administratively obsolete since 1898, they still appear on title deeds and planning applications - the legal ghost of an older Ireland, preserved in the small print.
When the Norman lords took possession after Henry's grant, according to Giraldus Cambrensis they claimed seven of the cantreds of Desmond and let the MacCarthys hold the remaining twenty-four under rent. Three cantreds east of Cork went to FitzStephen, four west to de Cogan. Neither knight left a male heir, and when King John came to the English throne he saw an opportunity. He sequestered the kingdom of Desmond to the Crown and parcelled it out among loyal subjects between 1200 and 1207. Richard de Cogan, nephew of Milo, was granted Muscraighe Mittaine - what would become Muskerry East. He was expected, the documents said, to take it by the sword. The Cogans built castles at Mourne Abbey, Maglin near Ballincollig, Dundrinan, Castlemore near Cookstown, Dooniskey, Mahallagh, and Macroom. About 1242, John de Cogan held the patronage of the churches of Clondrohid, Matehy and Kilshannig. The Norman grip seemed secure.
It did not last. The Battle of Callann in 1261 ended with the Cambro-Norman lords driven out by the MacCarthys, though their leader Finghin Mac Carthaigh was killed in the moment of victory. In 1280 the MacCarthy Reagh sept of Carbery made peace with the main branch of the family, whose king Domhnall Ruadh MacCarthy was Finghin's nephew, and the cousins divided Desmond between them. The Cogans gradually lost their lands. Successive English viceroys - Lionel of Antwerp in the 14th century, Thomas Rokeby - tried and failed to recover them. By 1398, the chronicler records, the MacCarthys were free to plunder from Dingle to the territory of the Barretts, and even to carry on their ancient feud with their cousins in Carbery at Carrigrohane. The kingdom that had been notionally lost in 1171 had been physically reclaimed by 1280, and the MacCarthys held it until the Tudor conquest. Their tower houses - Blarney, Kilcrea Castle, Carrignamuck at Dripsey - still stand across this landscape.
Muskerry East today contains, wholly or partly, twenty-five civil parishes. The River Lee bisects the barony east to west, although in the early Muscraige territory the kingdom didn't extend south of the river. Parishes share boundaries with no fewer than five other baronies - Cork city to the east, Barretts to the north-east, Muskerry West to the west, Kinalea to the south, Kinsale further south. The parish of Ballinaboy is split between four baronies. The parish of Knockavilly has nine of fifteen townlands in Muskerry East and six in Kinalea. Carrigaphooca Castle stands in the western part of the barony - another MacCarthy tower house, perched on a limestone outcrop above the River Sullane. The MacCarthy GAA tradition continues under the Muskerry GAA division of Cork GAA. The names on the modern map - Inniscarra, Carrigrohane, Donaghmore, Garrycloyne, Macroom - run continuously from Gaelic Ireland through Norman conquest, through reconquest, through the Tudor wars, through the Cromwellian transplantation, through the present day. The barony has outlasted the kingdom and the kingdom's conquerors.
Muskerry East is a polygonal administrative area centred approximately at 51.9197 N, 8.7382 W, running from the western edge of Cork city out to Macroom and from the River Lee valley northward to the Boggeragh foothills. Ballincollig is the chief town, sitting astride the Lee about 7 km west of central Cork. From the air the barony reads as the gently rolling pasture and forested ridges of mid-Cork, threaded by the Lee and dotted with the MacCarthy castle ruins. Cork Airport (EICK) is on the southern edge of the barony's eastern boundary. Kilcrea Friary and Carrignamuck Tower House at Dripsey are notable visible monuments.
