Jewish Population of Europe Before the Holocaust
Jews have lived in Europe for more than two thousand years. The American Jewish Yearbook placed the total Jewish population of Europe at about 9.5 million in 1933. This number represented more than 60 percent of the world's Jewish population, which was estimated at 15.3 million. Most European Jews resided in eastern Europe, with about 5 1/2 million Jews living in Poland and the Soviet Union. Before the Nazi takeover of power in 1933, Europe had a dynamic and highly developed Jewish culture. In little more than a decade, most of Europe would be conquered, occupied, or annexed by Nazi Germany and most European Jews--two out of every three--would be dead.
