Ruusan Reformation

The Ruusan Reformation was an event that restructured the entire Galactic Republic, 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 1,000 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 molding 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.

The Reformation presumably put an end to the Republic Dark Age. It was considered to be the start of the Golden Age of the Old Republic.

Simultaneously, Darth Bane's Sith Order also underwent their own reformation: the institution of 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 A New Hope 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&mdash;most notably the popular Tales of the Jedi sagas. However, in Attack of the Clones, 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&mdash;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&mdash;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.
