Star Wars: 10 Greatest Sith Lords You'll Never Forget

2. Darth Sidious/Palpatine

During his younger years Palpatine led a double life serving as the apprentice of Darth Plagueis while at the same time serving as the ambassador for the planet Naboo at the Republic Senate. While his master was busy trying to find the key to eternal life Palpatine was busy manipulating galactic politics to ensure he would rise to become Supreme Chancellor. This culminated in the Naboo crisis which lead to Palpatine winning the nomination to become Supreme Chancellor. Around this time Palpatine fulfilled the rule of two and killed Plagueis, thus began the next stage in Palpatines plan to rebuild the Sith Empire.

Palpatine orchestrated the devastating Clone wars, as more people perished in the conflict the people rallied to the Chancellor granting him more powers and allowing him to become more powerful than the Senate itself. As the war neared it's end Palpatine began the final phase in his plan, he executed Order 66 which instructed the Republic Clone armies to exterminate all Jedi across the galaxy, he also managed to sway the powerful young Jedi Anakin Skywalker into becoming his apprentice by manipulating his feelings over his wife.

With the Jedi all but exterminated and his powerful apprentice Darth Vader at his side Palpatine formed the Galactic Empire and placed himself as it's all powerful ruler. Although the power of his Empire was unlike anything that had ever been seen it was defeated by the fledgling Rebel Alliance, as for Palpatine he was finally defeated by his apprentice who fulfilled the prophecy of the one who would bring balance to the force.
