Brutus (Brut, Brute, Welsh Bryttys), a descendant of the Trojan hero Aeneas, was known in medieval British legend as the eponymous founder and first king of Britain. This legend first appears in the "Historia Britonum", a 9th century historical compilation attributed to Nennius, but is best known from the account given by the 12th century chronicler Geoffrey of Monmouth in his "Historia Regum Britanniae".
