History of the Britons (Historia Brittonum‪)‬

The History of the Britons (Latin: Historia Brittonum) is a purported history of the indigenous British (Brittonic) people that was written 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
