Fluxus is an international avant-garde group or collective that was founded and flourished in the1960s but still continues today.
What began as a challenge to the category of art initiated by the Futurists and Dadaists in the 1910s and 1920s came to fruition with the performance art movements, one branch of which was referred to as Happenings.appenings is not the name of a movement but the name of certain performance pieces that were generally more complicated and outlined than Fluxus events, like an improvisational theatrical work that involved the audience. They were more expressionistic and symbolic than Fluxus performances.
