 Rome chose no longer to rule directly in Germania east of the Rhine and north of the Danube, instead preferring to exert indirect influence by appointing client kings, which was cheaper than military campaigns.Italicus, nephew of Arminius, was appointed king of the Cherusci; Vangio and Sido became vassal princes of the powerful Suebi, etc.When indirect methods proved insufficient to control the Germanic tribes beyond the Rhine, Roman emperors occasionally led devastating punitive campaigns deep into Germania.
