Irish King Arthur?
Ironically, the film Excalibur was made in Ireland.
Odd that Arthur is seen as an English hero. If Arthur existed, he was a Briton, and would have talked a Celtic language like Irish or Welsh, and would have shared their culture. He would have fought the Angle and Saxon ancestors of the English, and he would view most English as descendants of invaders who had stolen the land of his people
So all you Anglo-Saxons, if Arthur ever returns, better book your tickets back home to where you came from. The Irish and Welsh will be taking over. Please switch off the power, and leave your keys in the latch.
