Star Trek, Behind The Scenes

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."
Roddenberry intended the show to have a highly 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 mankind what it might develop into, if only it would learn from the lessons of the past, most specifically by ending violence. An extreme example are the Vulcans, who had a very violent past but learned to control their emotions. Roddenberry also wanted to imply an anti-war message, as well as depicting the United Federation of Planets as if it was like an ideal, optimistic version of the United Nations. His efforts were somewhat thwarted by the network's concerns over marketability, e.g., they were opposed to Roddenberry's insistence on a racially diverse crew of the Enterprise.
