The man who was Prince of Wales in 1399 came from what dynastic English house?
Henry V of England Henry V (9 August 1386 – 31 August 1422) was King of England from 1413 until his death at the age of 36 in 1422. He was the second English monarch who came from the House of Lancaster.
Princess of Wales Princess of Wales (Welsh: "Tywysoges Cymru" ) is a British courtesy title held by the wife of the Prince of Wales, who is, since the 14th century, the heir apparent of the English or British monarch. The first acknowledged title holder was Eleanor de Montfort, wife of Llywelyn ap Gruffudd. It has subsequently been used by wives of post-conquest princes of Wales.
