Owain Glyndŵr (c.1349-c.1416) was the leader of a Welsh revolt against English rule between 1400 and 1409. Years of attempts to subordinate the Welsh to the English crown and harsh rule had created a climate ripe for popular revolt. Owain Glyndŵr was well placed to lead this rebellion. He was charismatic and directly descended from Welsh aristocracy and royalty.
Owain Glyndŵr's dispute with his neighbour Lord Grey of Ruthin, a close ally of Henry IV, sparked the revolt. After Owain Glyndŵr’s attack on Ruthin and other towns in north Wales Henry led an army into Wales and Glyndŵr’s lands were confiscated. Owain Glyndŵr and his forces embarked on a successful campaign of guerrilla warfare which developed into conventional battles. As he started to score ever more impressive victories Owain Glyndŵr’s fame spread throughout Wales. He drew increasing support from the Welsh eager to throw off the yoke of English rule.
