The Galactic Empire was a faction formed out of the Galactic Republic in 19 BBY and was the creator of the Stormtroopers. It was run by Emperor Palpatine and his apprentice, Darth Vader, who ruled over the Empire with an iron fist. The Imperial Stormtroopers that the Empire utilized around this time were mostly made up of clones until recruitment camps were opened up across the galaxy following a rebellion on Kamino.
