Commander Fox led the Coruscant Guard, an elite clone trooper unit assigned to serve as peace-keepers on the Galactic Republic capital. Like every other clone trooper in the Guard, Fox was bound by honor and duty to protect and serve the Supreme Chancellor and the members of the Galactic Senate. Utterly fearless, he was always the first to lead the charge into battle, even in the most perilous combat situations. His exemplary performance has made him one of the most highly decorated soldiers in the Republic army.
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.
Scheming, powerful, and evil to the core, Darth Sidious restored the Sith and destroyed the Jedi Order. Living a double life, Sidious was in fact Palpatine, a Naboo Senator and phantom menace. He slowly manipulated the political system of the Galactic Republic until he was named Supreme Chancellor -- and eventually Emperor -- ruling the galaxy through fear and tyranny.
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.
