Prince of Wales regard as having been the last native Prince. On 16 September 1400, he was proclaimed Prince of Wales by his supporters, and held parliaments at Harlech Castle and elsewhere during his revolt, which encompassed all of Wales. It was not until 1409 that his revolt in quest of Welsh independence was suppressed by Henry IV. The tradition of conferring the title "Prince of Wales" on the heir apparent of the monarch is usually considered to have begun in 1301, when King Edward I of England invested his son Edward of Caernarfon with the title at a Parliament held in Lincoln.
Coronet of Charles, Prince of Wales which was held at Caernarfon Castle on 1 July 1969. Coronets of Princes of Wales have been rarely used. The Coronet of Frederick, Prince of Wales was never actually worn by Frederick; and the Coronet of George, Prince of Wales was only worn rarely by George, later King George V, and by Edward, later King Edward VIII. The current Prince of Wales has not worn his coronet since his investiture; the coronet was carried before him when he took his seat in the House of Lords in 1970. The coronet was loaned to the National Museum and Gallery of Wales
