There is no doubting that Ireland was overrun by two gangs of ‘gurriers’; the Vikings, starting in 795, and the Normans in 1169. While one gang faded into the fabric of Irish society rather than conquering us, the other gang ignited our roughly 800-year-history with that larger island to our east. You could forgive our forebears for not seeing the Vikings coming, but how did the Normans take us by surprise?
