The Clone Wars are a series of fictional intragalactic battles in George Lucas's science fiction saga Star Wars. The conflict is first mentioned in the film, Star Wars Episode IV: A New Hope (1977), but no details are given (except for the implication of clones being involved), and the wars themselves are not featured until the series' fifth and sixth films, Attack of the Clones (2002) and Revenge of the Sith (2005), the second and third episodes of the six-part Star Wars film series. The 2D animated microseries Star Wars: Clone Wars (2003–2005) and 3D CGI animated series Star Wars: The Clone Wars (2008–present), chronicle some of the war's major campaigns. Additional events and stories are detailed in a multimedia campaign consisting of Star Wars literature and video games. Many of the events featured have parallels in history, politics, and mythology from which Lucas and other writers drew inspiration.
