Owain ap Gruffydd, commonly known as Owain Glyndŵr, was a prominent Welsh leader and military commander in the late Middle Ages. Born in 1354 in North East Wales, Glyndŵr came from a powerful Anglo-Welsh gentry family and had a claim to be hereditary Prince of Powys Fadog. He was an educated lawyer and joined the king's military service in 1384, undertaking garrison duty on the English-Scottish border and serving under prominent figures such as John of Gaunt and Richard FitzAlan. In 1400, a dispute with a neighboring English Lord escalated into a national revolt, leading to a 15-year-long Welsh revolt aimed at ending English rule in Wales. Glyndŵr gained control of most of Wales and was proclaimed as the Prince of Wales, garnering support from various European kingdoms. Despite facing setbacks, he continued to resist English rule through guerrilla warfare tactics until his disappearance in 1415.
