Once Hitler and the Nazis get power, they really get a stranglehold on it. They start persecuting their political opponents both outside the party and inside the party. And they also start to take action on these twisted ideas Hitler expressed in Mein Kampf. In 1935, they are able to pass the Nuremberg Laws which strips German Jews of their citizenship. It forbids intermarrying between non-Jewish Germans and Jews. This is only one of many steps that will continue to demean the rights of Jews inside of Germany. In 1938, you have what is known as Kristallnacht or the Night of Broken Glass.
