Historia Brittonum

The Historia Brittonum, or The History of the Britons, is a purported history of the indigenous British (Brittonic) people that was written during the Anglo-Saxon period. The text was written in around 828 and survives in numerous recensions, that date from after the 11th century.

The Historia Brittonum is commonly attributed to Nennius, as some recensions have a preface written in his name. Some experts have dismissed the Nennian preface as a late forgery, arguing that the work was actually an anonymous compilation
