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), Queen Elizabeth II's cousin. Earliest history A title associated with Kent first appears anciently with the Kingdom of Kent (or Cantware), one of the seven Anglo-Saxon kingdoms that later merged to form the Kingdom of England. The Kings of Cantware (or Kent) date back to about 449. After 825, when the Kingdom of Kent was taken over by Egbert, King of Wessex, Kent became a dependency of Wessex and was ruled by sub-kings, usually related to the Wessex rulers. The titular kingship became something like the heir-apparent's title, as Aethelwulf, Egbert's son, became King of Kent in 825. By 860, Kent lost its status as a kingdom, becoming absorbed into Wessex. Earls of Kent The first title of Kent was that of the Earl of Kent in the Peerage of England. After the death of Godwin, Earl of Wessex, his son Leofwine (c. 1035–1066) became Earl of Kent sometime between 1056 and 1058. After Leofwine's death at Hastings in 1066, William the Conqueror named his half-brother, Odo of Bayeux (c. 1036–1097), who was also Bishop of Bayeux, the new Earl of Kent. However, Odo was twice removed from this title. The first occasion was in 1082, when he was imprisoned; the second was in 1088, after aiding in the Rebellion of 1088, after which he fled England. It was not until 1141 that the title returned, this time for William de Ipres; but he was deprived of the title in 1155. In 1227, it was revived for Hubert de Burgh, but became extinct with his death. In 1321, it was again revived for Edmund of Woodstock, and through the marriage of Joan Plantagenet to Thomas Holland, the title passed to the Holland family, which held the title until 1408. In 1461, it was revived for William Neville, and then in 1465 for Edmund Grey. The Grey family held the title until Henry Grey, 12th Earl of Kent, who was made Marquess of Kent in 1706 and Duke of Kent in 1710, died without male heirs in 1740. Just before he died, he was awarded an inferior replacement title of Marquess De Grey
