In 1276 Edward perceived that Llewellyn had breached the Treaty of Montgomery. In what must be one of the greatest examples of overkill in medieval European history he mobilised the total forces of his realm, augmented by foreign troops and a large fleet, and in 1277 invaded Wales. The subsequent Peace of Aberconwy was breached by Welsh forces hostile to Llewellyn and in 1282 Edward pounced again. Llewellyn was killed in a skirmish, and his brother Dafydd was hunted down and hideously executed. A string of great concentric castles was built, and English law and customs began their march into the Welsh interior. The investiture of his son, Edward as [[Prince of Wales]] (which legend tells us was at Caernarvon Castle in 1284, but was in reality at Lincoln 17 years later) retained the perception of the State as a principality, but it was the principality belonging to the heir to the English throne. | In 1276 Edward perceived that Llewellyn had breached the Treaty of Montgomery.
