Darth Sidious

Sheev Palpatine was the humble Senator of Naboo in the Galactic Senate, prior to him being elected Supreme Chancellor. As such, he led the Galactic Republic against the Confederacy of Independent Systems throughout the Clone Wars to preserve "peace" in the galaxy.

But the Jedi Order discovered the truth of him being the ever-elusive Darth Sidious - the Dark Lord of the Sith and the Confederacy's shadowy leader - who had orchestrated the entire war. Sidious initiated the Jedi Purge and declared himself Galactic Emperor with the approval of the Senate. As ruler of the galaxy, Sidious keeps a tight grip on his dominion and has enforcers such as Wilhuff Tarkin, Darth Vader and the Inquisitor carry out his will and hunt down those who might be threat to his reign such as surviving Jedi Knights and rising insurgent groups.
