Nazi Germany established an authoritarian regime led by Adolf Hitler that controlled all aspects of life. The Nazi party used organizations like the SS and Gestapo secret police to oppress opposition and monitor citizens. Propaganda was pervasive, portraying Hitler and Nazis positively through rallies, the 1936 Olympics, and controlling media. The regime suppressed dissent by sending opponents to concentration camps and censoring speech. Most Germans accepted Nazi policies due to fear of retaliation, economic recovery, and anti-Communist stances.
