As the war drew toward its end, Tyrannus was killed and the Jedi learned of Palpatine's true identity as a Sith Lord.

He continued to centralize his own power to pave the way for his eventual ascension to Emperor. The war raged on for three years with the Clone Army's help for the Jedi to eliminate the Separatists, and Sidious remained remained in office at the will of the Senate far longer than his term technically allowed. These actions would culminate in the outbreak of the Clone Wars, the last conflict of the Republic, while Sidious himself 'reluctantly' accepted emergency powers. Besides persuading a dead Jedi Knight to create a secret clone army for the Republic, he also tasked his new apprentice, Darth Tyrannus with exacerbating political tensions in the Republic and engineering a Secessionist Movement. In the decade that followed, Sidious secretly manipulated galactic events to the extent that war became inevitable. The vote passed despite the Jedi getting in the invasion's way and defeating his apprentice Darth Maul, and in the subsequent election, Sidious, in his public persona of Palpatine, secured the position of Supreme Chancellor of the Republic for himself. Sidious used the crisis to manipulate the thenвЂ“Queen of the Naboo, PadmГ© Amidala, into calling a Vote of No Confidence against sitting Chancellor Finis Valorum.

For his rise to power, he orchestrated an invasion on his own homeworld Naboo made by the Trade Federation in order to create a leadership crisis in the Senate. In 32 BBY, Senator Sheev Palpatine, secretly the Sith Lord Darth Sidious, privately lamented the declining state of the Senate, noting that the Republic was 'not what it once was'. In the last decades of its existence, the Republic Senate became mired in bureaucracy, rendering it woefully ineffectual as a governing body, and a peacekeeping organization powered by the Force known as the Jedi swore to defend it from its enemies, such as a war bringing organization powered by the dark side of the Force known as the Sith. For at least a thousand years, the dominant governing body of the galaxy was the unicameral and democratic Galactic Republic, led by an elected Supreme Chancellor.
