Owain ap Gruffydd (28 May 1354 – 20 September 1415), commonly known as Owain Glyndŵr (Welsh pronunciation: [ˈoʊain ɡlɨ̞nˈduːr], also Glyn Dŵr; anglicised as Owen Glendower) was a Welsh leader, soldier and military commander in the late Middle Ages, who led a 15-year-long Welsh revolt with the aim of ending English rule in Wales. He was an educated lawyer, forming the first Welsh parliament under his rule, and was the last native-born Welshman to claim the title Prince of Wales.
During the year 1400, Glyndŵr, a Welsh soldier and Lord of Glyndyfrdwy had a dispute with a neighbouring English Lord, the event which spiralled into a national revolt pitted common Welsh countrymen and nobles against the English military. In response to the rebellion, discriminatory penal laws were implemented against the Welsh people; this deepened civil unrest and significantly increased support for Glyndŵr across Wales. Then, in 1404, after a series of successful castle sieges and several battlefield victories for the Welsh, Glyndŵr gained control of most of Wales and was proclaimed by his supporters as the Prince of Wales, in the presence of envoys from several other European kingdoms, and military aid was given from France, Brittany, and Scotland. He proceeded to summon the first Welsh parliament in Machynlleth, where he outlined his plans for Wales which included building two universities, reinstating the medieval Welsh laws of Hywel Dda, and build an independent Welsh church.
