- "In order to ensure our security and continued stability, the Republic will be reorganized into the First Galactic Empire, for a safe and secure society!"
- ―Darth Sidious
This era was characterized by many conflicts that engulfed the galaxy beginning with the Invasion of Naboo by the Trade Federation. The inaction of then Supreme Chancellor Finis Valorum during the crisis led him to be voted out of office and replaced as Chancellor by Naboo Senator Sheev Palpatine, who was secretly the Dark Lord of the Sith Darth Sidious. Further governmental inaction and corruption ultimately led to the Separatist Crisis in which thousands of worlds seceded from the Republic and formed a separate government, the Confederacy of Independent Systems. Tensions fostered between the two factions through the machinations of Sidious and his Sith apprentice, Count Dooku ultimately led to the outbreak of the pan-galactic Clone Wars in 22 BBY.
The Clone Wars raged on for three years, during which the Republic became an increasingly militarized state all in the name of order and security against the Separatist threat. Chancellor Palpatine, whose term was already extended due to the Separatist Crisis, continued to remain in office for the duration of the conflict, all the while centralizing political and military authority in the Office of the Chancellor through the various wartime emergency powers granted to him by the Galactic Senate.
In the waning days of the Clone Wars in 19 BBY, the Separatists would suffer a series of major defeats including the deaths of Dooku and General Grievous at the hands of Jedi Knight Anakin Skywalker and Jedi Master Obi-Wan Kenobi respectively. Meanwhile, the Jedi High Council, who became increasingly wary of Palpatine due to his unprecedented wartime powers, discovered his identity as the enigmatic Sith Lord Darth Sidious. The Jedi's attempt to apprehend him ultimately failed and fostered Skywalker's fall to the dark side and rechristening as Sidious' new apprentice, Darth Vader. Vader would be subsequently sent to attack the Jedi Temple. Simultaneously, Palpatine instituted Order 66 to the Grand Army of the Republic, beginning the initial part of the systematic destruction of the Jedi Order, as clone troopers executed their Jedi Generals across the galaxy.
With the Jedi Order decimated, Palpatine gave the Proclamation of the New Order to an emergency session of the Galactic Senate, where he declared the Jedi enemies of the state, while transforming the Galactic Republic into the Galactic Empire, with himself as Galactic Emperor. At the same time, Vader destroyed the Separatist Council and deactivated the droid army, effectively ending the Clone Wars and cementing the return of the galaxy to the rule of the Sith.
