The Alliance to Restore the Republic (commonly known as the Rebel Alliance, and, informally, as the Rebellion) is an interstellar faction of the fictional universe of Star Wars.
As a direct reaction to the Galactic Empire, the Rebel Alliance warred throughout the Star Wars galaxy for restoring the ideals of the Old Republic. The primary founders of the Rebellion were Senators Mon Mothma, Bail Organa, Padmé Amidala, and Garm Bel Iblis.
Originally, the Rebel Alliance was featured in the original trilogy of films, Star Wars Episode IV: A New Hope, Star Wars Episode V: The Empire Strikes Back, Star Wars Episode VI: Return of the Jedi, whereas its origins were referred in Star Wars Episode III: Revenge of the Sith.
The first antecedents of the Rebel Alliance are told by the expanded universe around Episode III. It is explained that the Delegation of 2000 is a group of Senators who are disgruntled about the already unjustified extraordinary powers of Supreme Chancellor Palpatine, as the Clone Wars were waning. The group included Padmé Amidala, Garm Bel Iblis, Mon Mothma, and Bail Organa, amongst others. Palpatine eventually transforms the Galactic Republic into the Empire with himself as its Emperor, and he immediately attacks such dissenters.
