Bróðir and Óspak of Man were two
Danish brothers who were active in the
Isle of Man and
Ireland in the 11th century. They are mentioned in the 12th century Irish
Cogadh Gaedhil re Gallaibh and the 13th century Icelandic
Njal's Saga as key leaders who fought on opposite sides in the
Battle of Clontarf in 1014. The latter account names Bróðir as the killer of
Brian Boru, the
High King of Ireland. Both Boru and Bróðir died in the battle, although accounts differ as to who killed whom. Óspak fought on the side of Boru, was injured, and lost his two sons in the battle.
