Julies. H. Palpatine.

Sheev Palpatine[3] (also known by his Sith identity Darth Sidious and publicly as Senator Palpatine, then Supreme Chancellor Palpatine, and later Emperor Palpatine) is a fictional character and the main antagonist of the Star Wars franchise,[4] mainly portrayed by Ian McDiarmid. In the original trilogy, he is depicted as Emperor of the Galactic Empire and the Sith master of Darth Vader. In the prequel trilogy, he is portrayed as a charismatic Senator from Naboo who uses Machiavellian deception and political manipulation to rise to the position of Supreme Chancellor of the Galactic Republic before transforming the Republic into the Empire.

Though outwardly appearing to be a well-intentioned public servant and supporter of democracy prior to being Emperor,[5] Palpatine's true identity is actually Darth Sidious, the Dark Lord of the Sith—a cult of practitioners of the dark side of the Force previously thought to have been extinct for millennia, and master of Darth Maul and Count Dooku.[5] As his Sith identity, Palpatine masterminds the Clone Wars, using the conflict as a convenient pretext to grant himself dictatorial emergency powers and to stay in office long after his term has expired.

Palpatine ultimately reorganizes the Republic into the Galactic Empire, invokes martial law, and declares himself Emperor. He then proceeds to all but exterminate the Jedi Order through Order 66, and manipulates Jedi Knight Anakin Skywalker into turning to the dark side and becoming his new apprentice, Darth Vader. Palpatine rules the galaxy for over two decades before his reign is brought to an end when Vader turns on his master and kills him in order to save his son, Luke Skywalker.

Since the initial theatrical run of Return of the Jedi, Palpatine has become a widely recognized symbol of evil in popular culture, and since the prequel films, also one of sinister deception and the subversion of democracy.
