Duke of Kent and Strathearn

History

Several Earls of Kent had previously been created in the Peerage of England. Henry Grey, 12th Earl of Kent was created Duke of Kent in 1710, but the title became extinct upon his death in 1740.

On 23 April 1799, the double dukedom of Kent and Strathearn was given, along with the Earldom of Dublin, to King George III's fourth son, Prince Edward Augustus. After the Union of Great Britain, the Hanoverian kings liked to grant double titles (one from one constituent country, one from another) to emphasise unity.

Edward had only one legitimate child, a daughter, Princess Alexandrina Victoria (the future Queen Victoria). Upon Edward's death in 1820, the dukedom of Kent and Strathearn became extinct, as he had no legitimate male heir.
