  • Notes 


    • Brian Bóruma was the first man to establish himself as High King of Ire l a n d b y f orce of arms alone in many centuries.

      Brian Boru (Middle Irish: Brian Bóruma mac Cennétig; modern Irish: Bria n B ó r a m ha; c. 941 - 23 April 1014) was an Irish king who ended the domi na t i o n o f the High Kingship of Ireland by the Uí Néill, and possibly en d e d V i k ing invasions of Ireland. Brian Boru was mentioned in Annals of I n i s f a llen and Chronicon Scotorum as "Brian mac Cennétig" (Brian, son of C e n n é t ig). The name Brian of Bóruma or Brian Boru was given to him posth u m o u s ly. Brian built on the achievements of his father, Cennétig mac Lo r c a i n , and especially his elder brother, Mathgamain. Brian first made h i m s e l f king of Munster, then subjugated Leinster, eventually becoming H i g h K i n g of Ireland. He was the founder of the O'Brien dynasty, and is w i d e l y r egarded as one of the most successful and unifying monarchs in m e d i e v al Ireland.
