An elite security force assembled to protect members of the
Galactic Senate, the Senate Guard were garbed in outdated yet symbolic blue robes and helmets. The stoic guards stood watch over the massive Senate rotunda on
Coruscant, and its members could be found aboard almost all senatorial transports.
Under the rule of Chancellor Palpatine, the role of the Senate Guard was steadily marginalized. Palpatine installed his own elite guard, the red-robed Royal Guardsmen, for the protection of his office. With the spread of his clone forces that accompanied the transition from Republic to Empire, the Senate Guard grew largely redundant and were eventually phased out.
