History of the Britons

"History of the Britons" (Latin: Historia Brittonum) is a historic manuscript of the indigenous British people that was originally written in Latin around 828 A.D. It is commonly attributed to the Welsh monk Nennius, as some early manuscripts have a preface written in his name. It describes the supposed settlement of Britain by Trojan expatriates and states that Britain took its name from Brutus, a descendant of Aeneas, a Trojan hero in Greco-Roman mythology.
