Owain Glyndŵr
Owain Glyndŵr (also known as Owain Glyn Dŵr and Owen Glendower), (c. 1355 – c. 1415) was the last person born in Wales to be Prince of Wales. He was prince between 1401 and 1416. He started the Welsh Revolt against Henry IV of England's rule of Wales. In the late 19th century, the Young Wales (Cymru Fydd) movement decided that he was the father of Welsh nationalism. Since then, he has been seen as a hero by the Welsh. There is a university in Wales that is called Glyndŵr University after him.
