The universe of Star Wars is set in a fictional galaxy that serves as the primary setting for the Star Wars multimedia and film franchise. Originally established by George Lucas as a "galaxy far, far away", it comprises numerous planets, moons, star systems, and species. The galaxy is divided into four broad sub-regions: the Core Worlds, Mid Rim, Outer Rim, and Unknown Regions. Notable planets include Coruscant, an ecumenopolis in the Core that functions as a political and cultural center, and Tatooine, a desert planet located in the Outer Rim. The universe initially encompassed a collection of works recognized as canon by Lucasfilm as part of the official Star Wars storyline. Subsequent expanded material in other media was later rebranded as the Legends universe by Disney, declaring it non-canonical to the official universe.
Within this fictional body exists a variety of intelligent species, including Humans, Twiβleks, Wookiees, Rodians, and Hutts, as well as several major governing bodies throughout galactic history, such as the Galactic Republic, Galactic Empire, Rebel Alliance, New Republic, and First Order. Each of these entities operates under differing political structures, ranging from democratic institutions to totalitarian regimes. Interstellar travel is facilitated by hyperspace, allowing rapid movement between distant star systems. A central metaphysical concept in the Star Wars universe is the Force, an omnipresent energy field that connects all living things. The Force is divided into two principal aspects: the Light Side, traditionally followed by the Jedi Order, and the Dark Side, embraced by the Sith. The universe also features a high level of technological advancement, including starships, droids, and energy-based weapons such as blasters and lightsabers. The timeline of in-universe events is often measured in reference to the Battle of Yavin, a pivotal conflict depicted in the original 1977 film, serving as a chronological anchor for subsequent developments in the franchise.
