Diarmaid III Macmael Nam Bo Ri Laigin Airdrigh na hEireann (Diarmait MacMáil nam Bó), zn. van Donnchadh Maolnambo Ui-Cennsaelaigh (King of Ui Chennselaig), koning van Ierland en Leinster, ovl. op 7 feb 1072.

Diarmaid III Macmael Nam Bo Ri Laigin Airdrigh na hEireann.
Diarmait, Máel na mBó, of Hieronymus Kinsale?.
Diarmait was King of Leinster from 1042 to 1052, at which time he became High King of Ireland, a post which he held from 1052 until his death on February 7, 1072.  When Dairmait became High King of Ireland in 1052, it appears that he resigned as King of Leinster and his son Murchad took over that post.

Brian Borumha Mumhan Airdrigh na hEireann
Brian Borumha Mumhan Airdrigh na hEireann (Brian Bórú, Brian Bórúma mac Cennetig), geb. circa 941, ovl. Clontarf [Groot Brittanië] tussen 18 apr 1014 en 23 apr 1014 .

Brian Borumha Mumhan Airdrigh na hEireann.
Brian Bórúma mac Cennetig, known popularly as Brian Bórú, is undoubtedly the most well known ard-rí (ARD-ree) or High King of Ireland of Ireland and arguably the only ard-rí who, like Ælfred the Great of England, actually controlled the entire country.  Brian Bórú was born circa 941 at Béal Bórú (from which he received his name), near Killaloe, County Clare, at a time when the Norse had secured many seaports and frequently plundered and harried the neighbouring countryside. In 976 he succeeded his brother Mathúin as king of Dál gCais and claimant to the kingship of Munster. By 999, after a series of wars, he was acknowledged as High King of Ireland. He reign was marked by continuous opposition. This came to a head in the early eleventh century. Máel Mórda, the king of Leinster, made an alliance with the Dublin Norse under Sigurd, Earl of Orkney and their overseas allies. Brian's forces defeated this union at Clontarf, about four miles north of modern Dublin, on Good Friday, April 23, 1014.  Brian, too aged to fight, was awaiting news of the battle when he was slain in his tent by a Viking intruder. The battle of Clontarf marked the end of any major Viking involvement in Irish wars.
From this point on, the role of the Norsemen in Ireland was largely peaceful, and they intermarried with the Irish and concentrated on developing trade. However, with the death of Brian Bórú in 1014, Ireland once again became an island of conflicting dynasties, with the High King unable to enforce acceptance by all the provinces.
