Kings of Osraige

The kings of Osraige (alternately spelled Osraighe and Anglicised as Ossory) reigned over the medieval Irish kingdom of Osraige from the first or second century AD until the late twelfth century. Osraige was a semi-provincial kingdom in south-east Ireland which disappeared following the Norman Invasion of Ireland. A number of important royal Ossorian genealogies are preserved, particularly MS Rawlinson B502, which traces the medieval Mac Giolla Phádraig dynasty back through Óengus Osrithe, who supposedly flourished in the first or second century.[1][2] and one in the Book of Leinster (also known as "Lebor na Nuachongbála").[3][4] Recent analysis of ninth and tenth century regnal succession in Osraige has suggested that in peaceful times, kingship passed primarily from eldest to youngest brother, before crossing generations and passing to sons and nephews.[5]

Early Kings of Osraige

The following kings are listed in all major genealogies, but originate from an early period in Irish protohistory, and likely stem from oral tradition.[6]

Kings of Osraige to 1103

The following is a synchronism of the kings of Osraige from historic times until the death Gilla Patraic Ruadh in 1103, after which the kingdom experienced some political fracturing.[7]

Kings of Osraige from 1103 to the Norman Invasion

Upon the death of king Gilla Patráic Ruadh in 1103, two smaller portions of the kingdom broke away from the central polity of Osraige; the area of Mag Lacha in the far north of Osraige became independently ruled by the Ua Caellaide clan, and Desceart Osraige ("South Osraige") in the very southern area of Osraige, ruled intermittently by rival members of the Mac Giolla Phádraig clan.

  • Finn Ua Caellaide (????-????) (ruled Clarmallagh independently from the rest of Osraige)
  • Donnchad Balc mac Gilla Patráic Ruaid (after 1119-1123) Probably the same Donnchad who accompanied the great fleet led by Toirdhealbhach Ó Conchobhair, king of Ireland on a predatory excursion, along with king of Leinster Éanna son of Murchadh, to consume the food supplies of Munster.[12]
  • Donnchad Dub (c.1121-c.1121)

  • Maelseachlainn Mac Gilla Patráic (1185-1194)[15]

Kings of Osraige from the Normans to the Tudors

The kingdom of Osraige did not fully disappear after the arrival of Norman mercenaries in Ireland, though it was greatly reduced in size. The lineage of Osraige's kings remained in power in the northern third of their original territory, having been pushed back through the arrival of William Marshal who sought to consolidate his wife's huge claim to Leinster, including Osraige. The lords who ruled this area were sometimes also known in the annals as "Princes of Ossory", kings of Upper Ossory, North Osraige or kings of Slieve Bloom. They maintained their independence from the Crown or any shire until the final submission of Barnaby McGillaPatrick in 1539 and his subsequent conversion to the title of 1st Baron Upper Ossory in 1541. However, because of the tumultuousness of the period, the record of succession is often ambiguous. The following list may include powerful members of different lines of the family, who may or may not necessarily have been inaugurated as king of Osraige per se, but who were likely recognized nonetheless as the de facto ruler or potential heir, and noteworthy enough for reference by the annalists.[16]

  • Donnell Clannagh Mac Gilla Patráic (fl. 1212-1219) Edmund Campion hailed him as a "peerless warrior".[17]
  • Donnagh mac Anmchadh mac Donnogh Mac Gilla Patráic (d. 1249) Hailed by the annalists as an outstanding captain and relentless foe of the English, he is recorded as often reconnoitering the English forces while wearing a variety of disguises.[18]
  • Jeffrey mac Donnell Clannagh Mac Gilla Patráic (d.1269) "King of Slieve Bloom".
  • Eochaghan Mac Gilla Patráic(?) (d. 1281)
  • Mollachlyn Mac Gilla Patráic(?) (fl. 1286) Paid the Crown £6 for peace in 1286, together with his brother Finn.
  • Donnogh Mac Gilla Patráic (d. 1324) Donnogh Mac Gilla Patráic,"Lord of Ossory" was summoned by Edward II to campaign with him in Scotland.
  • Donnell Duff Mac Gilla Patráic(?) (d. 1325) Slain by his own relatives.
  • Donough mac Jeffrey Mac Gilla Patráic (d. 1329-30)
  • Scanlan Mac Gilla Patráic (fl. 1333-6)
  • Carroll Mac Gilla Patráic (d. 1345)
  • Dermot Mac Gilla Patráic (fl. 1346) Launched an attach on the English garrison at Aghaboe; the nearby Abbey of which was burned as collateral damage in 1346.
  • Maelechlainn mac Jeffrey Mac Gilla Patráic (d. 1367)
  • Finghin (Fineen) mac Cellach Mac Gilla Patráic (d. 1383) Re-founded the burnt Abbey of Aghaboe for the Dominican Order in 1382.
  • Mac Gilla Patráic (d. 1396) "Lord of Ossory"[19]
  • Finghin (Fineen) Mac Gilla Patráic (d. 1443) Styled "King of Ossory" by the annalist. He was murdered with two of his sons in Kilkenny at the behest of MacRichard Bulter.
  • Seaghan (John) mac Finghin Mac Gilla Patráic (d. 1468) Buried with his wife Katherine, along with his son Brian and his wife Noirin O'More in "Kilpatrick's" mortuary chapel at the Priory of Fertagh, underneath a stone altar table carved with effigies of Seaghan and his wife Katherine in high relief.
  • Geoffrey mac Finghin Mac Gilla Patráic (d. 1489) Styled "King of Ossory" and "Lord of Ossory"; brother of Seaghan (John). Another brother, also named Fineen, avenged his father's murder by slaying the son of MacRichard Butler.
  • Brian na Luirech Mac Gilla Patráic (d. ca. 1511) Brian "na Luirech" ("of the mail coats") possess a several noteworthy genealogies amongst various annalists which trace his paternal descent back to Cerball mac Dúnlainge.
  • Brían Óg Mac Giolla Phádraig (c.1485–1575) The last king of Osraige; he became the first great Irish lord to adopt the Tudor policy of "surrender and re-grant", and thereby became Barnaby Fitzpatrick, 1st Baron Upper Ossory. From him spring the Barons and Earls of Upper Ossory and Barons Castletown.
