In 55 BC, Julius Caesar was preparing for an invasion of [[Roman Britain|Britain]], when several Germanic tribes, including the Ubii,<ref>[[Cassius Dio]], Book 39, discussing Caesar's actions in 55 BCE, offderrs slightly different motivation and sequence of events: "the Ubii, whose land was coterminal with the [[Sugambri]] and who were at variance with them, invoked his aid" ([https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Cassius_Dio/39*.html  on-line text]) and Caesar crossed the Rhine; this is Dio's single mention of the Ubii.</ref> crossed the Rhine river. This movement included the [[Usipetes]] and [[Tencteri]] tribes, who wished to relocate to avoid contact with the [[Suevi]]. Caesar, concerned that fighting might break out in the region and draw troops away from his planned invasion, marched toward the Rhine. He met with ambassadors from the Germanic tribe and offered them land with the Ubii and an alliance against the Suevi; however, Caesar soon became worried that the tribes were delaying until their cavalry could return.

Together with the [[Batavi (tribe)|Batavi]], the Ubii furnished soldiers for the [[Germanic bodyguard]], the personal bodyguard of the early Roman emperors.
