The Reality of Brian Boru mac Cennétig

Today, the popular interpretation of Brian Boru, a famous high king alive during medieval Gaelic Ireland, is that he died as a martyr for Ireland, unified Ireland into one nation, and drove the heathen Vikings from Ireland’s coasts. This interpretation has been about for a very long time, beginning at least 900 years ago when the Cogad Gáedel re Gallaibh was written (“Cogadh Gaedhel Re Gallaibh”). The Cogad Gáedel re Gallaibh was essentially political propaganda in the form of a book written by Brian Boru’s descendants in the 12th century that told the tale of Brian’s life and his wars with the Vikings. »
