Alaric [the older son] died that same year 410 A.D. Two years later, his kinsman Athaulf led the Visigoths into southwestern Gaul, where, in AD 418, Honorius was obliged to recognize their kingdom at Toulouse. The Vandals and other Germanic tribes who had crossed over the frozen Rhine on the last day of AD 406 now were in Spain under their leader, Genseric. Honorius permitted them to stay, as well, although there was little he could have done otherwise. In AD 423 Honorius died and eventually was succeeded by Valentinian III, who was still a child at the time. The Vandals crossed into North Africa, defeated the Romans there, and, in AD 439, conquered Carthage, which Genseric made his capital. In AD 451, Attila and the Huns, who already had become so powerful that they were paid an annual tribute by Rome, invaded Gaul, in alliance with the Vandals. They were defeated at the Battle of Châlons by the Visigoths under the command of Flavius Aetius, magister militum of the west. In AD 455, the death of Valentinian III served as a pretext for the Vandals to enter an undefended Rome, which they plundered for two weeks, carrying away the treasures of the Temple of Peace and the gilded bronze tiles from the Temple of Jupiter. Temple of Vespasian.
