Princess Of Wales

Princess of Wales is a title used since the 14th century by the wife of the Prince of Wales. The Princess is the apparent future queen consort, as "Prince of Wales" is a title reserved by custom for the heir apparent to the British throne, and earlier the English throne. The current title-holder is Catherine. When the title was first recorded it was not connected to the English throne; it developed in an independent Wales when it was held by Eleanor de Montfort, wife of the native Prince of Wales Llywelyn ap Gruffydd.
