Nudity is sometimes used as a tactic during a protest to attract public attention to a cause. The use of the tactic goes back to the Doukhobor social movement in 1914. The tactic has been used by other groups later in the century, especially after the 1960s. Like public nudity in general, cultural and legal acceptance of nudity as a tactic in protest also varies around the world.
Even in places where public nudity is tolerated, it is still unexpected enough that its use by activists as a deliberate tactic is often successful in attracting publicity from the media.
