The most important elements of nazi ideology were the following: uniting every german (aryan) nation, the denial of the Treaty of Versailles, and therefore the demand for the lost parts of Germany, the superiority of the german (aryan) race, and the inferiority of other races (such as jews, or bolsheviks). All these aspects of ideology were used in the propaganda of nazi Germany. They helped the leadership of the country by creating anger and hatred in the population, and finding groups to blame for the losses of the country. This, and the depression of Germany after World War 1 lead to a completely atomized, and easily controllable society. German society couldn't bear the fact that it wasn't only the leaderships fault, that they lost the war. They needed a more physical answer, an answer which made them feel confident enough to act. This answer was racism and chauvinism. Another important part of the ideology was the image of the "ultimate leader", who knew all the answers, and who's actions couldn't be questioned. This leader (thus this icon, this image) became Adolf Hitler, the leader of the NSDAP.
