“The most recent flood of newcomers, however, seemed different. The empire had always been able to absorb new people into its expanding body, and the immigrants had proved more often than not to be a source of strength, but times had changed. The empire was now on the defensive, and the Germanic peoples crossing its borders wanted its land, not its culture. They were coming on their own terms, unwilling to be absorbed, speaking their own languages, and retaining their distinct cultures. The influx of new blood was no longer the source of strength it had always been. For many of those watching the traditions of millennia getting swept away, the strangers seemed like a frightening wave threatening to overwhelm the empire.”
