Darth Sidious, a Force-sensitive human male, was the Dark Lord of the Sith who founded the Galactic Empire after toppling its predecessor, the Galactic Republic from within. Prior to his term as Supreme Chancellor and subsequent reign as the Galactic Emperor, Sidious was born approximately eighty-four years before the Battle of Yavin and given the name Sheev Palpatine during the Age of the Republic. A native of the Mid-Rim planet Naboo, Palpatine pursued a career in politics and eventually became his homeworld's representative in the Galactic Senate.
