Mas Amedda was a Chagrian male politician who served as the nominal leader of the Coruscant provisional government in the aftermath of the Galactic Civil War. During the Republic Era, he served as Vice Chair of the Galactic Senate from the chancellery of Finis Valorum to Sheev Palpatine. Amedda became the Grand Vizier of the Galactic Empire after Palpatine declared himself Galactic Emperor.

Amedda was from the planet Champala. He lived on the Core World Coruscant, capital of the Galactic Republic, where he served in Chancellor Valorum’s government as Vice Chair. During the Invasion of Naboo in 32 BBY, Queen Padmé Amidala traveled to the galactic capital seeking Republic intervention against the Trade Federation‘s occupation of her homeworld. Although Valorum was removed from office by a Vote of No Confidence, Amedda retained his position under Palpatine, the senator of Naboo who was elected as the new Supreme Chancellor. He served as one of Palpatine’s advisors during the Separatist Crisis; when Amedda recommended giving emergency powers to the Chancellor, Junior Representative Jar Jar Binks successfully proposed the motion to the Senate, allowing Palpatine to organize legions of clone troopers from Kamino into the Grand Army of the Republic in 22 BBY.

Amedda continued to serve in the Office of the Chancellor during the Clone Wars, supporting Palpatine’s decisions as a wartime leader. With the execution of Order 66 against the Jedi Order, Amedda witnessed the ascension of Palpatine—the Sith Lord Darth Sidious—as Emperor of the galaxy in 19 BBY. Amedda retained his power in the New Order, serving as Grand Vizier in the Imperial Ruling Council. After the Emperor was killed in 4 ABY, Amedda was forced to serve as a figurehead for Fleet Admiral Gallius Rax, the self-styled Counselor to the Empire. Following the Battle of Jakku in 5 ABY, Amedda surrendered the Empire to the New Republic by signing the Galactic Concordance. The Imperial government on Coruscant was replaced by a powerless provisional government with Amedda as its nominal leader. Amedda was remembered by history as a weak-willed sycophant of the Emperor.
