During the pre-war years of Hitler's power (1933 to 1939), some 3,000 Jews migrated to Sweden to escape Nazi persecution. Because Sweden was neutral during World War Two, it helped facilitate the rescue of relatively many Jews from Norway and Denmark: in 1942, 900 Norwegian Jews were given asylum from Nazi persecution in their home country, and, most importantly of all, almost the entire Danish Jewish community, some 8,000 people, was transported to Sweden in October 1943 ("see Rescue of the Danish Jews"). Swedish diplomat Raoul Wallenberg also saved thousands of Hungarian Jews in Budapest by providing them with "protective passports". He also rented thirty-two buildings, funded by the United States, and declared them Swedish diplomatic facilities, thus bringing them under protection of diplomatic immunity.
