Some surviving Hasidic Jews went to Antwerp, London or Montreal, but most went to Israel and to the United States. About sixty courts, many of them with fewer than fifty families, were transplanted to New York.
Today there are twelve principal Hasidic courts, though many of the smaller ones still exist.
Williamsburg, Brooklyn, was a community of Orthodox, but increasingly westernized, Jews from Germany, Austria, Czechoslovakia, Rumania and Poland. The largest Hasidic groups settling in Williamsburg were of Hungarian origin, the Satmar and the Klausenberg. The neighborhoods of Crown Heights and Boro Park developed into Hasidic centers at a slower pace then Williamsburg. The largest and most influential court in Crown Heights is the Lubavitch, whose adherents are mostly Polish. Currently, the Hasidic population in Boro Park is expanding rapidly.
