3975

According to Mavic Chen, 3975 was the year in which a non-aggression pact was signed that allowed for at least twenty-five years of peace. It was unclear, however, who the signatories to the pact were, aside from the government of the solar system. It was also not clear whether Mavic Chen's own government, or a predecessor, had signed in the name of the people of the solar system. (TV: The Daleks' Master Plan "The Nightmare Begins")
