Overview
Vortigern (; , ; ; ; Old Breton: Gurdiern, Gurthiern; ; , , , etc.), also spelled Vortiger, Vortigan, Voertigern and Vortigen, was a 5th-century warlord in Britain, known perhaps as a king of the Britons or at least connoted as such in the writings of Bede and Gildas. His existence is contested by scholars and information about him is obscure.
He may have been the "superbus tyrannus" said to have invited Hengist and Horsa to aid him in fighting the Picts and the Scots, whereupon they revolted, killing his son in the process and forming the Kingdom of Kent. It is said that he took refuge in North Wales, and that his grave was in Dyfed or the Llŷn Peninsula. Gildas later denigrated Vortigern for his misjudgement and also blamed him for the loss of Britain. He is cited at the beginning of the genealogy of the early Kings of Powys.
Medieval accounts
Gildas
The 6th-century cleric and historian Gildas wrote De Excidio et Conquestu Britanniae in the first decades of the 6th century. In Chapter 23, he tells how "all the councillors, together with that proud usurper" [omnes consiliarii una cum superbo tyranno] made the mistake of inviting "the fierce and impious Saxons" to settle in Britain. According to Gildas, apparently, a small group came at first and was settled "on the eastern side of the island, by the invitation of the unlucky [infaustus] usurper". This small group invited more of their countrymen to join them, and the colony grew. Eventually the Saxons demanded that "their monthly allotments" be increased and, when their demands were eventually refused, broke their treaty and plundered the lands of the Romano-British.
