Once Adolf Hitler had gained complete power of Germany as a dictator in March 1933, he set up policies to bring the country's people 'into line'. His desire to do this was fuelled by the belief that the German people were a superior race above all others, called the Aryans. He also believed that, in order to prosper, Germany needed to be 'purified' by setting the Aryans apart from such inferior races as the Jewish communities.
As soon as he came into power, Hitler persuaded President Hindenburg of the Reich government, to issue decrees to suspend all given civil liberties of the German people and politicians. The Enabling Act that followed in March allowed Hitler and the Nazis to establish policies in not do much to stop the endless tirade of hate directed at the Jews. When it became compulsory and military training was introduced, one million people refused to join the Hitler Youth Movement.
People were afraid of being associated with Jews because Hitler used force as well as the legal system to prosecute any who opposed him. Hitler pitted himself against all those against the 'Aryan' way of life so Germany could become a 'pure' master state. The Jews were treated extremely unjustly from the very beginning of Hitler's seizure of power and the level of discrimination rose to such a height that it was immensely difficult and virtually impossible to end.
