Hitler justified his invasion of Northwestern Czechoslovakia in the late 1930 by claiming that the Germans lived there. Since most of the people of Czech speak German, he said that they were under German rule so he invaded the place. He met the leader of Sudenten Germans who was Konrad Henlein and told him that he really wanted to resolve the questions of Czech about their future. Hitler pushed Henlein to make demand to the Czech government, a demand that could not be accepted. And this demand cause Czech fall.
