Adolf Hitler's cult of personality was a prominent feature of Nazi Germany (1933-1945), which began in the 1920s during the early days of the Nazi Party. Based on the Führerprinzip that the leader is always right, promulgated by incessant Nazi propaganda, and reinforced by Hitler's apparent success in fixing Germany's economic problems, his bloodless triumphs in foreign policy before World War II, and his early quick military successes in Poland and France, it eventually became a central aspect of Nazi control of the German people.
