Final answer:
Hitler's anti-Semitism can be attributed to his personal grudges and the prejudice he learned from others.
Step-by-step explanation:
Hitler's anti-Semitism can be understood by examining (a) his personal grudges and (b) the prejudice he learned from others.
(a) Personal grudges:
Hitler lived in Vienna before World War I and absorbed the rampant anti-Semitism of Austrian society. He developed his own theories about Jews and blamed them for his perceived problems. Hitler believed that Jews were responsible for every disaster in German history.
(b) Prejudice learned from others:
Anti-Semitism had been an undercurrent in European history for centuries. The Nazis, like other fascist parties, built their power by appealing to people's worst prejudices. Jews were scapegoated as a convenient target for the economic and social problems facing Europe in the 1930s.
