William De Braose
After William the Conqueror took the throne in 1066, Norman lords began to seize land in Wales. As you can imagine, the native Welsh people weren’t too happy about that. They particularly hated the 7th Baron of Abergavenny, a chap called William de Braose. De Braose was so ruthless he was nicknamed the ‘Ogre of Abergavenny’. And he certainly lived up to the name, murdering several Welsh chieftains at Abergavenny Castle in 1175 - on Christmas Day no less!
