Prince of Wales titled Princess of Wales. There was also no Prince of Wales for the first several years of the reign of Elizabeth II. Prince Charles was not named Prince of Wales until 1958, when he was nine years old. The title of "Princess of Wales" has always been held by the Prince's wife in her capacity as spouse of the heir apparent and therefore future queen consort. The current Princess of Wales is Camilla, Duchess of Cornwall, who automatically assumed the title upon her legal marriage to Prince Charles. Camilla however has chosen not to be publicly known by the title
Frederick, Prince of Wales The marriage negotiations foundered when Frederick William demanded that Frederick be made Regent in Hanover. Frederick also almost married Lady Diana Spencer, daughter of Charles Spencer, 3rd Earl of Sunderland and Lady Anne Churchill. Lady Diana was the favourite grandchild of the powerful Sarah, Duchess of Marlborough. The duchess sought a royal alliance by marrying Lady Diana to the Prince of Wales with a massive dowry of £100,000. The prince, who was in great debt, agreed to the proposal, but the plan was vetoed by Robert Walpole and the king. Lady Diana soon married John Russell, 4th Duke of Bedford.
