How did the Jews end up all over Europe before being put in concentration camps?
At the beginning of the 16th century, Poland had the largest concentration of Jews in the world. Few or no Jews lived in most of the lands west of Poland, but this situation changed in the 17th century, when Jews began to migrate back to the German states and to eastern France. In 1654 England readmitted Jews. In addition, many of the Marranos, who secretly maintained some form of Jewish identity on the Iberian Peninsula (Spain and Portugal), were able to resume open commitments to Judaism in Holland, southern France, and the German city of Hamburg. Basically, they have been circling the World for a long time.
