Kingdom of Desmond

The Meic Carthaig kingdom of south Munster: Kerry and west Cork, with the sub-kingdoms of Loch Lein, Fir Maige, Ui Echach (Ua Mathgamna), Corca Loigde (Ua hEidirsceoil) and the incoming Ui Suilleabain and Ui Donnabain.

It lost Cork and its plain to the English in 1177; its eastern border with the Cork English and de Burgh's Limerick is a raided belt.

Overlord

None in fact

The realm that morning

Domnall Mor is king and at war with the English of Munster; the country from the Shannon to Feardruim was laid waste by the English in 1199.

Threats

  • William de Burgh and the English of Cork and Limerick
  • Family division

Officers in 1200

  • Sub-kings: Ua Donnchada of Loch Lein, Ua Caim of Fir Maige (Finghin, d. 1201), Ua Mathgamna, Ua hEidirsceoil, Ua Suilleabain, Ua Donnabain of Ui Chairpre (Amlaib, killed 1201)

Coinage

None: the Irish kingdoms strike no coin; wealth and tribute are counted in cattle, and silver comes through the ports.

Rome and the Church

The Desmond sees (Cork, Cloyne, Ross, Ardfert) answer to Cashel; the bishop of Cork's see sits in the English city.

The host

The Desmond hostings. No figures.

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

Primary sources for this realm

Chronicles, registers, sagas and inscriptions written in or near 1200 that cover this entry. Each has its own page with editions, translations and where to read it.

  • Annals of Inisfallen, Anonymous (monks of Inisfallen, Kerry, and earlier of Emly and Lismore) (the manuscript was written in 1092 and continued at Inisfallen in many contemporary hands to 1450). The Munster chronicle, written in Kerry in a hand close to the events. Read online
  • Annals of the Kingdom of Ireland by the Four Masters, Various; compiled by Micheal O Cleirigh and others (1632 to 1636, from medieval annals now partly lost). A seventeenth century compilation but it draws on lost medieval annals, so its 1200 entries add names and incidents missing elsewhere: the Connacht war and the English of Meath and Munster, the deaths of Irish kings and churchmen across the island, and raids in Thomond and Desmond. Read online
  • Mac Carthaigh's Book (Miscellaneous Irish Annals), Anonymous (a Munster compilation) (compiled in the later Middle Ages from Munster annals; manuscript of the 17th century). A Munster annal with a Mac Carthaig and Desmond slant, giving for the years around 1200 the kings of Desmond and Thomond, their wars with each other and with the English of Cork and Limerick, and the castles the settlers were building.

  • The Topography of Ireland; The Conquest of Ireland, Gerald of Wales (Giraldus Cambrensis) (Topographia 1187 to 1188; Expugnatio 1189, revised later). The Conquest ends in 1185 and the Topography describes the island as Gerald saw it in 1183 to 1185, so neither covers 1200, but they explain the lordship of Ireland as John found it: the grants of Leinster and Meath, the de Courcy conquest of Ulster, the Irish kings and their customs, and Gerald's advice on governing the country.
