Dissident

A dissident, broadly defined, is a person who actively challenges an established doctrine, policy, or institution. When dissidents unite for a common cause they often effect a dissident movement.

The noun was first used in the political sense in 1940, with the rise of such totalitarian systems as the Soviet Union.

Famous quotes containing the word dissident:

    The dissident does not operate in the realm of genuine power at all. He is not seeking power. He has no desire for office and does not gather votes. He does not attempt to charm the public, he offers nothing and promises nothing. He can offer, if anything, only his own skin—and he offers it solely because he has no other way of affirming the truth he stands for. His actions simply articulate his dignity as a citizen, regardless of the cost.
    Václav Havel (b. 1936)
