Vandalism
- For vandalism of pages on Wikipedia, please see Vandalism on Wikipedia.
Throughout history, the destruction of monuments of a previous government or power has been one of the greatest symbols showing the attempt at transition of power. Recent cases of Vandalism in this vein include the toppling and destruction of Soviet monuments after the fall of the Soviet Union and the Taliban destruction of Buddhist statuary in Afghanistan. In a country with an unpopular dictator, vandalism of the leader's portraits and other elements of his personality cult can be a common form of dissent.

With the rise and development of the World Wide Web came unauthorized and undesired modification of webpages through cracking, another form of vandalism.
Some vandalism qualifies as culture jamming or sniggling - artistic statements in their own right that are illegal and destructive from the point of view of the legal system, but are done with a creative and artistic impulse. Graffiti art qualifies in some cases at least, also billboard liberation and crop circles. Indeed the Situationist Asger Jorn founded the Scandinavian Institute of Comparative Vandalism.
