The man who was Prince of Wales in 1399 came from what dynastic English house?
Dunstable Swan Jewel The Dunstable Swan Jewel is a gold and enamel brooch in the form of a swan made in England or France in about 1400 and now in the British Museum, where it is on display in Room 40. It was excavated in 1965 on the site of Dunstable Friary, and is presumed to have been intended as a livery badge given by an important figure to his supporters; the most likely candidate is probably the future Henry V of England, who was Prince of Wales from 1399.
House of Wessex The House of Wessex, also known as the House of Cerdic ("Cerdicingas" in Old English), refers to the family that initially ruled a kingdom in southwest England known as Wessex, from the 6th century under Cerdic of Wessex until the unification of the Kingdoms of England by Alfred the Great and his successors (Though Alfred's grandfather Egbert was the one to start consolidating West saxon domination). Alfred and his successors would also be part of this dynasty, which would continue ruling in the main line all the way until Alfred's descendant, Ethelred the Unready, whose reign in the late 10th century and early 11th century saw a brief period of Danish occupation and following his and his son Edmund Ironside's death, kingship by the Danish Cnut the Great and his successors to 1042. The House of Wessex then briefly regained its power for 24 years, but after the deposition of its last scion, Ethelred's great-grandson Edgar Atheling would fade into the annals of history after the death of Edgar Atheling in 1125.
