Ruusan Reformation The Ruusan Reformation was an event that restructured the entire Galactic Republic following the New Sith Wars , taking power away from the Supreme Chancellor and reinvesting it in the Galactic Senate . Reformation . The reforms were enacted by then - Chancellor Tarsus Valorum and also resulted in the Republic Measures & Standards Bureau resetting the year zero to the year of the Seventh Battle of Ruusan , which would come to be known as 1000 BBY by the Galactic Standard Calendar . The system of government did not seem to change too dramatically ( as the Republic had been ruled by a Supreme Chancellor and the Galactic Senate as early as 15 , 000 BBY ) but the Jedi Order underwent a significant adjustment . In symbolic measures , largely to convince the Republic that they would not become a conquering army , the Jedi abandoned their battle armor , renounced all military ranks ( such as " Jedi Lord " ) , dissolved their commander - in - chief , disbanded their army , naval and starfighter forces , and placed themselves under the supervision of the Supreme Chancellor and the Judicial Department , effectively dissolving the Military . In order to lessen the chance of a Sith resurgence , the Order began training children from birth . In addition , the training of Padawans was centralized on Coruscant , to remove the danger of unsupervised students delving into forbidden Sith knowledge . Politically , however , the Reformations did affect representation within the Senate . In an effort to remove corruption and decentralize power away from a few powerful Coreward sectors that held the most representation , Valorum took the then - existing millions of sectors and reorganized them into only 1 , 024 sectors . Each of the new sectors were granted its own Senator , although a few exemptions were made for politically powerful core worlds to retain their individual representation . Other slots , such as those for species types and cultural entities were also granted . The Reformation Act was a critical piece of legislation . The Reformation put an end to the Republic Dark Age . It was considered to be the start of the Golden Age of the Old Republic . In some cases , such as Palpatine ' s Declaration of a New Order marking the transition of the Old Republic to the Galactic Empire , this event was even marked to be the " official " founding of the Old Republic . Simultaneously , Darth Bane ' s Sith Order also underwent its own reformation , reorganizing into the Rule of Two . Behind the scenes . The Ruusan Reformation was introduced in the timeline in order to explain several differences between the Old Republic as presented in the comics , and the one which appeared in the prequel trilogy . In the Expanded Universe , the Republic is well established to be extant for 25 , 000 years , based on Obi - Wan Kenobi ' s line in " " that the Jedi had been " the guardians of peace and justice in the Old Republic " " for over a thousand generations . " For a long time , EU sources were the only works set during the Republic era — most notably the popular " " sagas . However , in " " , Palpatine mentioned the Republic had " stood for a thousand years . " This at first seemed to conflict with both the C - canon EU history and the G - canon internal continuity in the films . However , the Ruusan Reformation — in which the Republic is reorganized following the already - established defeat of the Sith a thousand years prior to the films at the Seventh Battle of Ruusan — was invented by subsequent writers to give an alternate explanation on Palpatine ' s line , thus bringing all these sources into relative harmony through a retcon . It also explains how Sio Bibble could claim , in " Attack of the Clones " , that there had not been a full - scale war since the formation of the Republic . The necessity of the " Ruusan Reformation " remains a topic of much debate , Palpatine ' s statement that the Republic had " stood for a thousand years " might have been hyperbole - in other words the equivalent of saying the Republic had " stood forever " and was not meant to be taken literally . Given Palpatine ' s nature as a politician , prone to making grandiose statements and generalizations , gives great weight to this argument . Sio Bibble ' s remark could also be taken the same way , he may not have considered the Expanded Universe earlier wars as " full - scale " or alternatively there could have political revisions to the official Republic history ( such as there are in real life ) that could have led to majority public opinion that there " had " been no earlier wars , when in fact there had been .
