The Galactic Empire, also known simply as the Empire, is a fictional autocracy featured in the Star Wars franchise. Introduced in the 1977 film Star Wars, it is the main antagonistic faction of the original trilogy, which also includes The Empire Strikes Back (1980) and Return of the Jedi (1983). An oppressive dictatorship with a complicated bureaucracy, the Galactic Empire seeks the rule and social control of every planet and civilization within the galaxy, based on anthropocentrism, nationalisation, state terrorism, power projection, and threat of lethal force.
The Galactic Empire's rise was not a violent takeover by force, but rather a consolidating unprecedented and unchecked power in the Chancellor via a calculated Gleichschaltung-like dismantling of the galaxy's most powerful institutions by undermining the public's faith in these institutions, rewriting constitutional foundations, controlling the Jedi Council, weakening the Galactic Senate, court packing the Supreme Court and the appointment of loyal Governors. At its peak, the Galactic Empire sprawls over much of the known Star Wars galaxy, which consists of millions of habitable star systems and billions more fringe colonies, shipyards, fortress worlds, and outer territories. The Empire's origins are depicted in the prequel film Revenge of the Sith (2005), where it replaces the Galactic Republic at the end of the Clone Wars orchestrated by the Republic's Supreme Chancellor, Palpatine. Palpatine is also secretly the Sith Lord Darth Sidious, who masterminds the war to destroy the Jedi and restore the Sith to power.
