Star Trek is an American science fiction franchise.
In addition to six television programs including the original 1966 Star Trek, the same fictional universe created by Gene Roddenberry is the setting for ten feature films, dozens of computer and video games, hundreds of novels and other fan stories, as well as a themed attraction in Las Vegas.
In Star Trek's fictional universe, humans developed faster-than-light space travel after barely surviving a 21st-century World War III.
Later, humans united with other sentient species of the galaxy to form the United Federation of Planets.
As a result of alien intervention and science, humanity has largely overcome many Earth-bound frailties and vices by the 23rd century.
Star Trek stories usually depict the adventures of humans and aliens who serve in the Federation Starfleet.
