Star Trek
Conception and setting

As early as 1964, 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"—he privately told friends that he was 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.

Most Star Trek stories depict the adventures of humans and aliens who serve in Starfleet, the space-borne humanitarian and peacekeeping armada of the United Federation of Planets. The protagonists have altruistic values, and must apply these ideals to difficult dilemmas.

Many of the conflicts and political dimensions of Star Trek are allegories of contemporary cultural realities. The Original Series addressed issues of the 1960s, just as later spin-offs have tackled 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, feminism, and the role of technology. Roddenberry stated: " 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. If you talked about purple people on a far off planet, they (the television network) never really caught on. They were more concerned about cleavage. They actually would send a censor down to the set to measure a woman's cleavage to make sure too much of her breast wasn't showing."

Roddenberry intended the show to have a progressive political agenda reflective of the emerging counter-culture of the youth movement, though he was not fully forthcoming to the networks about this. He wanted Star Trek to show what humanity might develop into, if it would learn from the lessons of the past, most specifically by ending violence. An extreme example is the alien species known as the Vulcans, who had a violent past but learned to control their emotions. Roddenberry also gave Star Trek an anti-war message and depicted the United Federation of Planets as an ideal, optimistic version of the United Nations. His efforts were opposed by the network because of concerns over marketability, e.g., they opposed Roddenberry's insistence that Enterprise have a racially diverse crew.
