“The Queen has today been pleased to confer a Dukedom on Prince William of Wales. His titles will be Duke of Cambridge, Earl of Strathearn and Baron Carrickfergus,” Her Royal Highness’s Press Secretary reported.”Prince William thus becomes His Royal Highness The Duke of Cambridge, and Miss Catherine Middleton on marriage will become Her Royal Highness The Duchess of Cambridge.”
The Duke of Cambridge has been a royal title since the reign of Charles II in the 1600s. Before the wedding, it was considered to be the frontrunner in the title race, as the last holders of the title came from Queen Mary’s family, and Prince William’s great-great-great-great grandfather, Prince Adolphus Frederick, was the first modern Duke of Cambridge.
