In 58 AD, Tacitus reports in his "Annals" that the Ampsivarii, in their plea to the Romans concerning some land north of the Rhine reserved by the Roman military, that it had belonged in sequence to the Chamavi, Tubantes, and then the Usipii. (The Usipii are known to have moved into the Rhine region around the time of Caesar (55 BC), but not yet to have found permanent settlement in that time, and to have been resident at the afore-mentioned northern bank of the Rhine by the time of Drusus around 11 AD.)
