Sure, here are three ways each dictator took full control of their country before WWII:
Benito Mussolini in Italy:
Establishment of a one-party state: Mussolini's National Fascist Party became the only legal political party in Italy in 1926, which meant that all opposition parties were banned, and Mussolini became the sole leader of Italy.
Suppression of free speech and press: Mussolini's regime censored the press and restricted freedom of speech, ensuring that the media only reported positively on the government and Mussolini.
Creation of a cult of personality: Mussolini presented himself as a charismatic leader, using propaganda to create an image of himself as a heroic and all-powerful figure who embodied the Italian nation.
Adolf Hitler in Germany:
Suspension of civil liberties: After the Reichstag Fire in 1933, Hitler used emergency powers to suspend civil liberties such as freedom of speech, press, and assembly. This allowed him to suppress political opposition and consolidate his power.
Control of the military: Hitler created the Schutzstaffel (SS) and the Gestapo, which were loyal only to him and acted as his personal police force. He also gained control of the military, making himself the commander-in-chief, and purged anyone who opposed him.
Propaganda and indoctrination: Hitler used propaganda to create a cult of personality around himself and to promote the ideology of Nazism. He also indoctrinated young people through the Hitler Youth organization, which emphasized obedience, loyalty to Hitler, and racial superiority.
Joseph Stalin in the Soviet Union:
Purges and show trials: Stalin launched a series of purges and show trials in the 1930s, targeting anyone who opposed him or was suspected of disloyalty. This allowed him to eliminate potential rivals and consolidate his power.
Collectivization: Stalin forced peasants to give up their private land and join collective farms, which were controlled by the government. This allowed Stalin to control the food supply and eliminate opposition from the countryside.
Propaganda and censorship: Stalin used propaganda to create a cult of personality around himself, portraying himself as a heroic and all-powerful leader. He also censored the press, literature, and art, ensuring that only positive portrayals of the government and Stalin were allowed.
