Alleged scientific findings of racial differences were used by Nazi Germany to justify the racialist policy with its concept of "Großdeutschland" (Greater Germany) and the Nordic race idea. The Nazis' attitude towards the Jews were anti-Semitic and falsely blamed them for Germany's defeat in World War I and the Great Depression. The Nazis and some of their anti-Semitic allies, like Hungary, committed genocide against the Jews during the Holocaust of World War II.
