Answer:
Step-by-step explanation:
Hitler developed the myth that the Aryan people were supreme and everyone else, (particularly the Jews) was inferior -- much inferior. The war in Russia was so vicious because, in part, Hitler also hated slavs.
The 1936 Olympics was supposed to be Hitler's showcase where in he proved the superiority of Aryans.
The most publicized events were the 100,200, long jump and the 400 meter or yard (sorry don't remember which) race. All 4 were won by 1 person who was an African American. That was shattering. Hitler didn't even hang around to congratulate the winner.
His great plan backfired.
