Answer:
Hitler and the Nazi Party used nationalism to gain support by appealing to German pride in their national identity and history. Hitler promised to restore German greatness, blaming the Jewish people and other enemies for Germany's problems. He also portrayed the Nazi Party as defenders of German culture and values and used the fear of communism to rally support. Hitler's call for expansion into Eastern Europe, called Lebensraum, further bolstered nationalist sentiment and paved the way for Germany's aggressive foreign policy leading up to World War II.
