Glendower, Owen, properly Owain Glyndwr c.1350-c.1416
Welsh rebel

Born in Montgomeryshire, he claimed descent from Llywelyn ap Gruffydd. He quarrelled with Lord Grey (1401) over some lands and, unable to obtain redress from Henry IV, carried on a guerrilla warfare against the English lords of the Marches which became a national war of independence. He proclaimed himself Prince of Wales, and in 1402 captured Lord Grey and Sir Edmund Mortimer, both of whom married Glendower's daughters and joined him in coalition with Henry Percy (Hotspur). That coalition ended in the Battle of Shrewsbury (1403), won by Henry IV. In 1404 Glendower entered into a treaty with Charles VI of France, who in 1405 sent a force to Wales. Glendower, though often defeated, kept fighting until his death.
