Germanic peoples under Roman protection
At the time at which the Roman legionaries camp arose on the left bank of the Rhine, a Germanic embankment folk settled in the right Rhine region who called themselves Ubiers or Uviers.
Already at the time of Caesar, i.e. about one hundred years previously, they were reliable allies of the Romans. The Ubiers had concluded an aid and non-aggression pact with them which was regarded by other Germans in the right Rhine regions with displeasure.
The Romans therefore made the Ubiers the suggestion that they move to the fortified areas on the left side of the Rhine. The Ubiers took this opportunity to come across from the right Rhine bank at around 38 before Christ and placed themselves under the protection of the occupying power.
The imperial general, Marcus Vipsanius Agrippa, managed this resettlement and soon the children of the Ancient Germans and the Roman traders and veterans were playing in the streets of the Ubier settlement. Released soldiers married Rhine girls and Germanic people as well as Gauls and Romans, who had moved there, lived in harmony under the protection of the military.
