Final answer:
In his Reichstag speech, Adolf Hitler blamed the Jewish race for economic problems and social unrest, reinforcing the anti-Semitic ideology of the Nazi Party which led to the Nuremberg Laws and the Holocaust.
Step-by-step explanation:
In Adolf Hitler's Reichstag speech on January 30, 1939, he identified the Jewish race with d. Economic problems and social unrest. This was a continuation of the persistent anti-Semitic themes present in his 1925 book, Mein Kampf, and the underlying ideological basis of the Nazi Party that associated the Jewish people not only with economic difficulties but also with a host of society's ills, including communism and capitalism - an inconsistent conspiracy that held Jews as culprits behind various global crises. This rhetoric intensified the dehumanization of Jews, climaxing in the oppressive Nuremberg Laws and eventually leading to the Holocaust.
