The country had been devoted to Richard; and so notorious was its disaffection to the new line that when Henry's son knelt at his father's feet to receive a grant of the Principality a shrewd bystander murmured, "He must conquer it if he will have it." The death of the fallen king only added to the Welsh disquiet, for in spite of the public exhibition of his body he was believed to be still alive.

Some hold that he had escaped to Scotland, and an impostor who took his name was long maintained at the Scottish Court.

In Wales it was believed that he was still a prisoner in Chester Castle.

But the trouble would have died away had it not been raised into revolt by the energy of Owen Glyndwr or Glendower.

Owen was a descendant of one of the last native Princes, Llewelyn-ap-Jorwerth, and the lord of considerable estates in Merioneth.
