In 1941–1942 during the occupation of Norway by Nazi Germany, there were at least 2,173 Jews in Norway. At least 775 of them were arrested, detained and/or deported. More than half of the Norwegians who died in camps in Germany were Jews. 742 Jews were murdered in the camps and 23 Jews died as a result of extrajudicial execution, murder and suicide during the war, bringing the total of Jewish Norwegian dead to at least 765 Jews, comprising 230 complete households. "Nearly two-thirds of the Jews in Norway fled from Norway". Of these, around 900 Jews were smuggled out of the country by the Norwegian resistance movement, mostly to Sweden but some also to the United Kingdom). Between 28 and 34 of those deported survived their continued imprisonment in camps (following their deportation)—and around 25 (of these) returned to Norway after the war.
The Jewish community in Norway was established in the late 19th century, after a clause in the Norwegian constitution of 1814 that banned Jews from entering Norway was repealed in 1851. The population grew slowly until the early 20th century, when pogroms in Russia and the Baltic states increased the number of immigrants. Another immigration increase came in the 1930s, as Jews fled Nazi persecution in Germany and areas under German control. See also Nansenhjelpen.
By 1942, there were 2,173 Jews in Norway. Of these, it is estimated that 1,643 were Norwegian citizens, 240 were foreign citizens, and 290 were stateless.
Much of the prejudice against Jews commonly found in Europe was also evident in Norway in the late 19th and early 20th century, and Nasjonal Samling (NS), the Nazi party in Norway, made antisemitism part of its political platform in the 1930s. Halldis Neegaard Østbye became the de facto spokeswoman for increasingly virulent propaganda against Jews, summarized in her 1938 book Jødeproblemet og dets løsning (The Jewish Problem and its Solution). NS had also started gathering information about Jewish Norwegians before the war started, and antisemitic op-ed articles were occasionally published in the mainstream press.
