In 61 BC, Ariovistus, chieftain of the Suebi tribe and a king from the Germanic peoples, resumed the tribe's migration from eastern Germania to the Marne and Rhine regions. Despite this migration encroaching on Sequani land, they sought Ariovistus' allegiance against the Aedui. In 61 BC, the Sequani rewarded Ariovistus with land following his victory at the Battle of Magetobriga. Ariovistus settled the land with 120,000 of his people. When 24,000 Harudes joined his cause, he demanded the Sequani give him more land to accommodate them. This demand concerned Rome because if the Sequani conceded, Ariovistus would be able to take all of their land and attack the rest of Gaul.
