Majorian is arrested near Tortona (northern Italy) and deposed by the Suebian general Ricimer as puppet emperor.

Majorian was Western Roman emperor from 457 to 461. A prominent commander in the Western military, Majorian deposed Avitus in 457 with the aid of his ally Ricimer at the Battle of Placentia. Possessing little more than Italy and Dalmatia, as well as some territory in Hispania and northern Gaul, Majorian campaigned vigorously for three years against the Empire's enemies. In 461, he was murdered at Dertona in a conspiracy, and his successors until the fall of the Empire in 476 were puppets either of barbarian generals or the Eastern Roman court.

Tortona is a comune of Piemonte, in the Province of Alessandria, Italy. Tortona is sited on the right bank of the Scrivia between the plain of Marengo and the foothills of the Ligurian Apennines. Its frazione of Vho is one of I Borghi più belli d'Italia.

The Suebi or Suebians were a large and powerful group of Germanic peoples during the Roman era, who originated near the Elbe river region in what is now north-eastern Germany, but subsequently came to be a dominant influence in much of non-Roman Germania, which Romans conceived of as stretching from Roman borders on the Rhine and Danube, to Scandinavia and the Vistula river. Although the Roman empire succeeded in imposing its hegemony over much of the region in the first century AD, a major alliance of Suebian peoples formed, based around the powerful Marcomanni and Quadi, who lived near the Roman Danube frontier, and the cultural leadership of the Semnones on the Elbe. Starting in the third century, after the defeat of the main Suebian alliance in the Marcomannic Wars of the late second century, many Suebian groups moved into the Roman empire itself, beginning with the takeover of the Agri Decumates region in about 260 by diverse groups, eventually including the [[Juthungi, who were a branch of the Semnones. These Suebi eventually came to be known as the Alamanni, but by the Middle Ages they were more commonly known as Swabians. This tendency increased dramatically in the fifth century, as the central government of the Western Roman empire collapsed. Their name survives today as Swabia, which is still a major cultural region in the southwest of modern Germany. It also in numerous placenames found over much of continental Europe, including as far west as Portugal and Spain, where a major Suebian kingdom was created which lasted until 585.
