When did Jews spread among countries in history?

/kloc-At the end of 0/9 century, thousands of Jews fled here due to the intensification of persecution in Eastern Europe, most of whom went to the United States, Canada and Western Europe. By 1924, * * * about two million Jews had immigrated to the United States, because the attitude of American society towards the Jewish community was relatively more tolerant than that of Eastern Europe. The persecution of Jews in Europe finally reached its peak during the Great German Empire, and a massacre of about 6 million Jews took place, which almost completely destroyed the cultural and historical precipitation of Jews in Europe in 2000.
