Star Trek, Behind The Scenes

Conception and setting
As early as 1961, Gene Roddenberry drafted a proposal for the science fiction series that would become Star Trek. Although he publicly marketed it as a Western in outer space—a so-called "Wagon Train to the Stars" (like the popular Western TV series)—he privately told friends that he was actually modeling it on Jonathan Swift's Gulliver's Travels, intending each episode to act on two levels: as a suspenseful adventure story and as a morality tale.
Star Trek stories usually depict the adventures of humans and aliens who serve in Starfleet, the spaceborne humanitarian and peacekeeping armada of the United Federation of Planets. The protagonists are essentially altruists whose ideals are sometimes only imperfectly applied to the dilemmas presented in the series. The conflicts and political dimensions of Star Trek sometimes represent allegories for contemporary cultural realities: Star Trek: The Original Series addressed issues of the 1960s, just as later spin-offs have reflected issues of their respective decades. Issues depicted in the various series include war and peace, the value of personal loyalty, authoritarianism, imperialism, class warfare, economics, racism, religion, human rights, sexism and feminism, and the role of technology. Roddenberry stated: "By creating a new world with new rules, I could make statements about sex, religion, Vietnam, politics, and intercontinental missiles. Indeed, we did make them on Star Trek: we were sending messages and fortunately they all got by the network."
