What Brittonic dialect was spoken in the kingdom who had the father of Owain mab Urien as king?
Owain mab Urien Owain mab Urien (or Owein) (died c. 595) was the son of Urien, king of Rheged c. 590, and fought with his father against the Angles of Bernicia. The historical figure of Owain became incorporated into the Arthurian cycle of legends where he is also known as Ywain, Yvain, Ewain or Uwain. In his legendary guise he is the main character in Chrétien de Troyes's "Yvain, the Knight of the Lion" and the Welsh Romance "Owain, or the Lady of the Fountain", which corresponds to Chrétien's poem.
English people The English are a nation and an ethnic group native to England, who speak the English language. The English identity is of early medieval origin, when they were known in Old English as the "Angelcynn" ("family of the Angles"). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. England is one of the countries of the United Kingdom.
