Hengist (or Hengest in Old English) and Horsa is two brothers originating in the Jutland (Denmark) which, according to the tradition, would have carried out their people during the invasion of the Great Britain and base the first Anglo-Saxon kingdom on the island: the kingdom of Kent, in the south-east of England.

They were - according to Bède Worthy the, in the ecclesiastical Histoire of the English people , and according to the Anglo-Saxon Chronique , written by anonymous hands as soon as possible in VIIIe century - guests by the Breton king Vortigern in 449 to help the Bretons to defend oneself against the Pictes and the Écossais in north.

They settled then in Kent and fought under the orders of Vortigern before revolting against him. Horsa died at the time of the Bataille of Aylesford and Hengist became king of Saxon who were in the island.

If the names of Hengist and Horsa are perhaps mythical, the historians generally agree on the fact that at the 5th century, a chief jute and his warriors arrived in Kent to serve mercenaries in the internal wars that the Breton ones were delivered. As, it is probable as the tradition reported by the history of Hengist and Horsa is a reminiscence of the origins of the establishment of the Jutes in Kent.
