Dear Student,
The reason of Nazi hatred for Jews are as follows:-
(i) Nazi hatred of Jews had a precursor in traditional Christian hatred of Jews because they believed that the Christ was killed by the Jews.
(ii) The Jews were mainly involved in trade and money lending activities and were hated as usurers or money-lenders. Nazi projection of Jews as pests and rodents living off society struck a chord with the deprived and the unemployed.
