The primary ideology of the Nazi Party in Germany was rooted in extreme nationalism, militarism, and Aryan supremacy, combined with anti-Semitism. Adolf Hitler and the Nazis propagated the belief that Germans, particularly those of Aryan descent, were superior to other races. This ideology justified discriminatory policies against Jews and other minority groups, leading to the Holocaust. The Nazis aimed to create a totalitarian state centered on the Führer's authority, emphasizing aggressive expansionism and the revival of the German economy through military buildup and propaganda. This toxic mix of nationalism and racism had devastating global consequences, leading to World War II.
