Racism and antisemitism were basic tenets of the Nazi Party and the Nazi government.[12] Discrimination and violent attacks against Jews began immediately after the seizure of power in 1933.[13] Violence and economic pressure were used by the Nazis to encourage Jews to voluntarily leave the country.[14] By 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Argentina, the United Kingdom, Palestine, and other countries.[15][16]
