Description Star Trek Flag United Federation of Planets
Show with the Star Trek Flag United Federation of Planets that you, as a human, are a member of that memorable interstellar alliance that was founded on Earth in San Francisco on October 11, 2161, shortly after the end of the Earth-Romulan War.
If you hoist this flag on a flagpole in your front yard or at a festival in front of your tent, it means that you are committed to the directives of this union, adhere to them, and uphold them: Above all, this of course applies to the so-called Prime Directive, which establishes the prohibition of interference in the affairs of peoples who have not yet discovered warp drive.
So you always have a suitable excuse when someone asks you for a favor: "I'm sorry, but as you can see from this flag here, due to the non-interference directive, I am not allowed to help you as long as your people have not developed warp drive" ;)
