Duke of Kent is a title that has been created several times in the peerages of Great Britain and the United Kingdom, most recently as a royal dukedom for the fourth son of King George V. Since 1942, the title has been held by Prince Edward (born 1935), a first cousin of Queen Elizabeth II.

The titular kingship became something like the heir-apparent's title, as Aethelwulf, Egbert's son, became King of Kent in 825.

Just before he died, he was awarded an inferior replacement title of Marquess De Grey to allow this to be passed to his heir - his granddaughter (the Dukedom could not be inherited).

In 1710 he was elevated once again as Duke of Kent, and following the death of his sons, Marquess Grey (1740) with a special remainder to his granddaughter.

By the time of Henry's death in 1740, both of his sons had died, Anthony (in 1723) and George (in 1733), leaving the Duke of Kent without a male heir.

On 23 April 1799 the double dukedom of Kent and Strathearn was given, with the earldom of Dublin, to King George III's fourth son, Prince Edward Augustus.

Upon Edward's death in 1820, the dukedom of Kent and Strathearn became extinct, as he had no legitimate male heir.

Great-grandchildren of the sovereign in the male line enjoy the courtesy titles of the children of dukes.

As a direct descendant of Queen Victoria, this is not the coat of arms of the present Duke of Kent.
