Tacitus later wrote that it was in this very region that the term "Germani" started to be used, even though he mentions a tribe Caesar did not mention, the Tungri.The name Germany, on the other hand, they say, is modern and newly introduced, from the fact that the tribes which first crossed the Rhine and drove out the Gauls, and are now called Tungrians, were then called Germans ["Germani"]. Thus what was the name of a tribe, and not of a race, gradually prevailed, until all called themselves by this self-invented name of Germans, which the conquerors had first employed to inspire terror.
