The Battle

History & Significance

A major Norse fleet from Dublin attacked Anglesey in 877, the year before Rhodri Mawr was killed fighting the Mercians. The raid was part of the intensified Norse activity in the Irish Sea following the establishment of Dublin as a major Viking base. Anglesey was devastated and its population scattered. The island was known to the Norse as Mona and was repeatedly targeted for its fertile farmland and monastic wealth.
