At the height of its rule, the Galactic Republic was governed by a body of Senators representing the many worlds of the galaxy. Within the cavernous Senate rotunda, hundreds of politicians would fill the viewing platforms that lined the curved walls. The Senate’s power gradually eroded after it voted emergency powers to Supreme Chancellor Palpatine during the Clone Wars, and the body was sharply divided between supporters of the war and those seeking peace. After Palpatine declared himself Emperor, power was increasingly wielded by regional governors. Shortly before the Battle of Yavin, Palpatine disbanded the Senate.
For centuries, the Senate Guards have kept the galaxy's legislators from harm while they go about the Republic's business on the capital world of Coruscant. The best and bravest members of the guard are invited to become members of the Senate Commandos, who carry out secret government missions. With the decline of the Republic, the blue guards would eventually be phased out by Imperial stormtrooper patrols and the red guard in the Emperor's service.
A city-covered planet, Coruscant is the vibrant heart and capital of the galaxy, featuring a diverse mix of citizens and culture. It features towering skyscrapers, streams of speeder-filled air traffic, and inner levels that stretch far below the world’s surface. Coruscant was the seat of government for the Galactic Republic and the Empire that followed, and was the site of numerous historic events during the Clone Wars. It also housed the Jedi Temple and Archives, which hosted Jedi training and learning for over a thousand generations -- traditions that ended when the planet bore witness to Order 66.
