Galactic Senators were planetary representatives who served in the Galactic Senate during the time of the Galactic Republic. Queen Sabé Arcadia of Utapau, who served as her planet's monarch during the Invasion of Utapau in 22 BBY, believed that most Galactic Senators were corrupt, and that uncorrupted senators—such as Malus Palpatine—were a rarity. Senators often served on committees, such as the Galactic Senate Armed Services Committee. Galactic Senators were replaced by Imperial Senators when the Galactic Empire's Imperial Senate replaced the Old Republic's legislative body.
