Usipetes

The Usipetes or Usipii (in Plutarch's Greek, Ousipai,^[1] and possibly the same as the Ouispoi of Ptolemy^[2]) were an ancient Germanic people who entered the written record when they encountered Julius Caesar in 56/55 BC when they attempted to find a new settlement west of the Rhine, together with the Tencteri, who were both attempting to move away from the aggressions of the Suevi on the east side of the Rhine. After the Romans slaughtered a great number of both tribes, they resettled on the east bank with the help of the Sicambri.

By about 100 AD, in the time of the Roman author Tacitus, the Usipii and Tencterii had moved southwards along the eastern bank of the Rhine into a position between the Chatti and the river. During the reign of Gallienus around 260-268 AD, the Laterculus Veronensis, reports that the Romans lost control of the Usipii lands, and after this they no longer appear in historical records.
