Luke Skywalker died in Star Wars: Episode VIII - The Last Jedi by projecting himself across the galaxy through the Force to deceive Kylo Ren and give the Resistance a chance to escape. This act of astral projection put immense strain on his mind, body, and soul, ultimately causing his death. He peacefully disappeared into the Force, similar to the way Obi-Wan Kenobi did, becoming one with it after this final sacrifice. This death symbolized his transformation and selflessness, a spiritual culmination of his journey rather than a combative end. Mark Hamill, who plays Luke, described it as Luke "overdosing on the Force," as the great effort to reconnect with the Force after years of distancing himself was fatal to him.
