text: When works feature galactic empires that truly do span most or all of their parent galaxy, they usually depict their capital as a "core world", a planet in a star system relatively close to a galaxy's supermassive black hole. Typically, "core worlds" will be portrayed as wealthier and more politically powerful than "rim worlds" closer to the edge of the galaxy. However, this portrayal, while common, is not universal; many works may invert this dynamic or reject it altogether.
  Second, the "empire" in "galactic empire"  is also misleading, as it suggests the empire's government is authoritarian to at least some degree, if not completely autocratic. While many galactic empires do correspond to this description, many do not: galactic empires may adhere to any real-world political philosophy, or a unique form of governance created by the work's author(s). A prominent example of a non-autocratic galactic empire is the Galactic Republic of the Star Wars prequel trilogy, which is a hybrid regime parliamentary democracy (albeit one that collapses into fascist dictatorship over the course of the story).
  Notable examples
  Star Wars
  The best known such organization to the general public today is the Galactic Empire from Star Wars, which was formed in turn from the Galactic Republic.
  Star Wars depicts an empire ruled autocratically by Darth Sidious, supported by a powerful space navy. It is stated in the original Star Wars film that there was an Imperial Senate that was later disbanded by the Emperor. There was a galactic empire called the Sith Empire founded by Darth Revan. This galactic power was close to overthrowing the Jedi's Republic during the Jedi Civil War.
