After a long struggle between the OBriens of Munster, the O'Connor's of Connaught and the Mac Lochlainn's from the north, the high-kingship of Ireland was finally won by Muirchertach Mac Lochlainn (1161), a victory which suited Dermod, Mac Lochlainn's ally. But MacLochlainn's death (1166) brought to an end the northern alliance and left the way open for the rise to the high-kingship of King Roderick O'Connor of Connaught, aided by King Tighernan O'Ruairc of Breifni. Both O'Connor and O'Ruairc were enemies of Dermod, and when O'Ruairc advanced into Leinster (late 1166) Dermod was deposed.

Dermod returned to Ireland (1167) with a small band of Normans, Flemings and Welshmen and earned for himself the epithet Diarmuid-na-nGall [Diarmuid of the foreigners]. He re-established himself in his old territory of Clan Chenselaigh, but little attention was paid to this minor victory.

Dermod renewed his claim to his lost title of King of Leinster. The high-king moved against him and he was defeated. He was allowed to retain Clan Chenselaigh on condition that he recognised O'Connor's supremacy and abandoned his claim on Leinster. O'Ruairc used the occasion to extract an indemnity for the personal injury he had suffered through Dermod eloping with his wife, Dervorgilla.

But Dermod was only biding his time, and in 1168 he went across to England to solicit succour from King Henry II (being entertained on the way at Bristol by Robert, feudal Lord of Berkeley). Further reinforcements came over from Wales (May 1169) under Maurice Prendergast, Hervey de Montmorency and Robert FitzStephen. He once more took to the field, but was again defeated by O'Connor. Following negotiations a treaty led to Dermod being recognised as King of Leinster on the understanding that he recognised O'Connor as high-king, and (in a secret clause) sent his foreign allies back whence they came.

Dermod was no more to be trusted in 1169 than in 1167. He wrote to Richard FitzGilbert de Clare, Earl of Pembroke, urging him to redeem his promise of aid made during the original Norman help (1167). He offered Richard the prospect of succession to the kingdom of Leinster and the high-kingdom of Ireland, though both prospects involved violation of Irish laws of succession. With the permission (afterwards revoked) of King Henry II, Richard de Clare determined to take the chance. He sent Maurice FitzGerald and Raymond Carew to Ireland, and prepared to follow them later. Richard arrived with a strong force (August 1170), and within two days had captured Waterford, and a few days later married Dermod's daughter, Eva. Dublin was captured a month later, where Dermod and Richard appointed Miles de Cogan as its constable.

The high-king then reminded Dermod of his promise at the treaty of 1169. The reply was Dermod's ambition to defeat the Irish armies, overthrow the existing government and win the high-kingship for himself (and thus for his heir, Richard).

Dermod died shortly after at Ferns (1st May 1171), leaving Richard as King of Leinster, and heir to the programme of the complete conquest of Ireland.

[MACM372] Aoife (Eva) (daughter of Dermod & Mor) married (at Waterford Cathedral, August 1170) [PEMB361] Earl Richard (see PEMBROKE (CLARE) EARLDOM).
