Star Wars is an American epic space opera media franchise created by George Lucas, which began with the eponymous 1977 film and quickly became a worldwide pop culture phenomenon. The franchise has been 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.

Space opera is a subgenre of science fiction that emphasizes space warfare, with use of melodramatic, risk-taking space adventures, relationships, and chivalric romance. Set mainly or entirely in outer space, it features technological and social advancements in faster-than-light travel, futuristic weapons, and sophisticated technology, on a backdrop of galactic empires and interstellar wars with fictional aliens, often in fictional galaxies. The term does not refer to opera music, but instead originally referred to the melodrama, scope, and formulaicness of operas, much as used in "horse opera", a 1930s phrase for a clichéd and formulaic Western film, and "soap opera", a melodramatic television series. Space operas emerged in the 1930s and continue to be produced in literature, film, comics, television, video games and board games.
