Despite the partial resettlement of Jews in Western Europe following the Thirty Years' War (1618–1648), a great majority of world Jewry had lived in Eastern Europe (in the Commonwealth and in the regions further east and south, where many migrated), until the 1940s.
尽管在三十年战争（1618年-1648年）有部分犹太人重回西欧定居，全世界绝大多数犹太人仍生活在东欧（联邦乃至更加偏东偏南的地方，很多人迁至那里），直到1940年代。
