Art intervention is an interaction with a previously existing artwork, audience, venue/space or situation. It has the auspice of conceptual art and is commonly a form of performance art. It is associated with the Viennese Actionists, the Dada movement and Neo-Dadaists. Stuckists have made extensive use of it to affect perceptions of artworks they oppose and as a protest against existing interventions.
Intervention can also refer to art which enters a situation outside the art world in an attempt to change the existing conditions there. For example, intervention art may attempt to change economic or political situations, or may attempt to make people aware of a condition that they previously had no knowledge of. Since these goals mean that intervention art necessarily addresses and engages with the public, some artists call their work “public interventions.”
