Lucas drew heavily on World War II imagery: Imperial officers wear uniforms resembling those of German forces, stormtroopers take their name from World War I shock troops, and the planet Hoth is named after German general Hermann Hoth. He originally conceived the Sith as serving the Emperor in the same way the Schutzstaffel served Adolf Hitler, condensing that structure into the single figure of Darth Vader.
