Darth Sidious, a Force-sensitive human male, was the Dark Lord of the Sith and Galactic Emperor who ruled the galaxy from the fall of the Galactic Republic to the fragmentation of the Galactic Empire. Rising to power in the Galactic Senate as Senator Sheev Palpatine, he was elected to the office of Supreme Chancellor and, during the Clone Wars, accumulated wartime powers in the name of security. As the Emperor, he dropped the facade, no longer needing to cultivate two identities, and henceforth ruled as Darth Sidious in thought and action, though he was known by many as just the Emperor. His machinations brought an end to the last era of peace in galactic history, replaced a millennium of democracy with New Orderfascism, and restored the Sith to power through the destruction of the Jedi Order.
