To the west, Theodoric at his accession found his kingdom bounded by the Alps, for Odoacer had given up to the Visigoths Marseilles, and the other towns which had obeyed the emperor down to the year 476. Beyond the Alps, Alaric the Visigoth now held the mouths of the Rhone and the Provençal Coast, while Gundobad the Burgundian ruled on the middle and upper Rhone, from Avignon as far as Besançon and Langres. North of both Burgundian and Visigoth, and far from the Alpine borders of Theodoric, lay the new Frankish kingdom of Chlodovech, now reaching as far as the Loire and the upper Seine. With all these three monarchs the king of the Ostrogoths had many dealings. At the very beginning of his reign he asked for the hand of Augofleda, the sister of Chlodovech, and hoped that by this alliance he had bound the clever and unscrupulous Frank to himself. By Augofleda he became the father of Amalaswintha, the only child born to him in lawful wedlock, though he had two elder daughters by a concubine ere he came to Italy. [Sidenote: Marriages of Theodoric’s family.] Soon after his own marriage with the Frankish princess, Theodoric wedded one of these natural children to Sigismund, the son and heir of the Burgundian Gundobad, and the other to Alaric the Visigoth. Thus all his neighbours became his relatives. But this did not secure peace between the new kinsmen of Theodoric. In 499 Chlodovech fell on Gundobad, to strip him of his realm, routed him, and shut him up in Avignon, the southernmost of his strongholds; but after many successes the Frank lost all that he had gained, and turned instead to attack the king of the Visigoths. Theodoric strove unsuccessfully to prevent both wars, and was not a little displeased when, in 507, his brother-in-law Chlodovech overran southern Gaul, and slew his son-in-law Alaric in battle. Burgundian and Frank then united to destroy the Visigoths, and might have done so had not Theodoric intervened. The heir of the Visigothic throne was now Amalric, the son of Alaric and of the king of Italy’s daughter. To defend his grandson’s realm Theodoric declared war both on Chlodovech and on Gundobad, and sent his armies over the Alps to save the remnants of the Visigothic possessions in Gaul. One host crossed the Cottian Alps, and fell on Burgundy; another entered Provence, and smote the Frank and Burgundian besiegers of Arles. With his usual good fortune, Theodoric recovered all Gaul south of the Durance and the Cevennes (509), so that the conquests of Chlodovech were confined to Aquitaine. The way was now clear for the Ostrogothic armies to march into Spain, to support the claims of the child Amalric against Gesalic, a bastard son of Alaric II., who had been proclaimed king of the Visigoths at Barcelona. After two years of guerilla fighting, the pretender was hunted down and slain, though he had sought and obtained some help from the Vandal king Thrasamund (511).
