Star Wars canon

Star Wars canon is the depiction of Star Wars storylines and characters considered officially canon to the franchise by its owner, Lucasfilm. Canon material is represented in media designated as such by the company.

A large number of derivative Star Wars works have been produced in conjunction with, between, and after the original trilogy (1977–83) and prequel trilogy (1999–2005) of films. This body of work was collectively known as the Star Wars Expanded Universe for decades, and a hierarchy of canonicity was created and maintained by Lucasfilm to organize its content. The Walt Disney Company acquired Lucasfilm in October 2012, and in April 2014 Lucasfilm rebranded the Expanded Universe material as Star Wars Legends and declared it non-canon to the franchise.

Post-2014, the official Star Wars canon consists of the eight released Star Wars theatrical feature films, the Star Wars animated film, the television series The Clone Wars and Star Wars Rebels, multiple novels and comics, and any other material released after April 25, 2014, unless otherwise stated.

George Lucas's original trilogy of films—Star Wars (1977), The Empire Strikes Back (1980), and Return of the Jedi (1983)— was followed decades later by a prequel trilogy which included the films The Phantom Menace (1999), Attack of the Clones (2002), and Revenge of the Sith (2005).
