(born circa 1354—died 1416) Self-proclaimed prince of Wales who led an unsuccessful rebellion against England. Educated in England, he returned to Wales and touched off an uprising against Henry IV (under whom he had previously fought) in northern Wales in 1400. He was soon in control of most of Wales and had set up a Welsh Parliament. In 1403 his alliance with English nobles was crushed at Shrewsbury, and a later French alliance also failed; his strongholds at Aberystwyth and Harlech fell to the future Henry V in 1408–09. Glendower nonetheless remained active as a guerrilla warrior as late as 1412. His rebellions were the last major Welsh attempts to throw off English rule.
