Star Wars is an American media franchise created by George Lucas. The space opera saga began with the original Star Wars film (1977) and quickly became a worldwide pop culture phenomenon. It has expanded into various films and other media, including television series, video games, novels, comic books, theme park attractions, and themed areas, comprising an all-encompassing fictional universe. Star Wars is one of the highest-grossing media franchises of all time.
The original film, later retitled Episode IV: A New Hope, was followed by the sequels Episode V: The Empire Strikes Back (1980) and Episode VI: Return of the Jedi (1983), forming the original Star Wars trilogy. Lucas later returned to the series to write and direct a prequel trilogy, consisting of Episode I: The Phantom Menace (1999), Episode II: Attack of the Clones (2002), and Episode III: Revenge of the Sith (2005). In 2012, Lucas sold his production company to Disney, relinquishing his ownership of the franchise. This led to a sequel trilogy, consisting of Episode VII: The Force Awakens (2015), Episode VIII: The Last Jedi (2017), and Episode IX: The Rise of Skywalker (2019).
All nine films, collectively referred to as the "Skywalker Saga", were nominated for Academy Awards, with Oscars going to the first three releases. Together with the spin-off films Rogue One (2016) and Solo (2018), the combined box office revenue of Star Wars theatrical live-action films equals over US$10 billion, making Star Wars the third-highest-grossing film franchise in cinematic history.
Star Wars stories are set in a fictional galaxy in the distant past. They span multiple fictional eras, in which humans and many species of aliens (often humanoid) co-exist with droids (robots), which may be programmed for personal assistance or battle. Space travel between planets is common due to lightspeed hyperspace technology. The various planets depicted contain a range of societies, from wealthy, planet-wide cities to deserts scarcely populated by primitive tribes. Virtually any Earth biome, along with many fictional ones, has its counterpart as a Star Wars planet which, in most cases, teem with sentient and non-sentient alien life.
The universe of Star Wars is generally similar to the real universe but its laws of physics are less strict allowing for more imaginative stories. One result of that is a mystical power known as the Force which is described in the original film as "an energy field created by all living things ... [that] binds the galaxy together". Through training and meditation, those whom "the Force is strong with" exhibit various superpowers; these are wielded by two major knightly orders: the Jedi (light side) and the Sith (dark side).
The franchise is set against a backdrop of galactic conflict involving rebellions, republics and empires. The Jedi and Sith prefer the lightsaber, a retractable blade of plasma. While the franchise is best known as an archetypal space opera, the combination of science fiction and fantasy elements makes Star Wars very universal, capable of telling stories of various genres.
