At the end of the fourth century, living conditions for the civilian population north of the Alps were still bearable.

Stilicho's campaign against Alarik in the Gothic War in 403 and the passage of Radagaisus army in 405 had been spared them.

Nevertheless, the population increasingly experienced the adverse consequences of the exhausting wars that the army waged to maintain the Roman Empire.

As a result of the internal conflicts and defensive battles against barbarians, the population experienced an increasing tax burden.

Historians see these deteriorating economic conditions as the main cause of the dissatisfaction that led to the Nori uprising in the years around 430/431.

[3] Aetius, appointed magister equitum praesentalis since 429[4] and thus in rank equal to Felix, ended his campaign against the Goths at Arles and put his army into position.

[9] In 431 Aetius resumed his campaign in the northern Alps, this time he deployed his army against the rebellious inhabitants of the province of Noricum.

The tension between the quirky general and Galla Placidia led her to put all her pawns on Bonifatius and she dropped Aetius.

When Aëtius left Italy in 432 to participate in the war against the Franks, she lets Bonifatius return from Africa and appoints him as her new commander in chief.

A number of contemporary historians: Priscus, Prosper, Hydatius report on a campaign against the Juthungi and the Nori in 430 and 431 by Aëtius.

If one maintains the order of Hydatius' events, Aëtius first campaigned against a group of Goths near Arles in the early spring of 430, before targeting the Juthungen and Nori.
