In Arthur and the distinctive genre of literature that had grown up around the celebration and adaption of his mythical exploits, King Edward I of England found not only a role model but a political tool every bit as puissant as the legendary king himself. Through the conscious emulation and glorification of the Arthurian ideal, King Edward would come within a hair’s breadth of matching Arthur’s legacy, the unification and domination of the British Isles.
