The Brut or Roman de Brut by the poet Wace is a loose and expanded translation in almost 15,000 lines of Norman-French verse of Geoffrey of Monmouth's Latin History of the Kings of Britain. It was formerly known as the Brut d'Engleterre or Roman des Rois d'Angleterre, though Wace's own name for it was the Geste des Bretons, or Deeds of the Britons. Its genre is equivocal, being more than a chronicle but not quite a fully-fledged romance.

Historia regum Britanniae, originally called De gestis Britonum, is a pseudohistorical account of British history, written around 1136 by Geoffrey of Monmouth. It chronicles the lives of the kings of the Britons over the course of two thousand years, beginning with the Trojans founding the British nation and continuing until the Anglo-Saxons assumed control of much of Britain around the 7th century. It is one of the central pieces of the Matter of Britain.
