The Ruusan Reformations represent a significant moment in the Galactic Republic's timeline, characterized by a reduction in the authority wielded by the Supreme Chancellor. Subsequently, the enactment of the Emergency Powers Act preceding the Clone Wars, coupled with the adoption of the Reflex Amendment to the Galactic Constitution during the war, elevated Sheev Palpatine's Chancellorship to a level of power unseen since these Reformations.
The name of the Ruusan Reformations is the same as the Mid Rim planet called Ruusan.
The canon sourcebook titled Collapse of the Republic marked the initial reference to the Ruusan Reformations. Within the framework of Star Wars Legends continuity, the Ruusan Reformations involved a reorganization of the Galactic Republic following the supposed destruction of the Sith.
