The roots of performance art can be traced back to early 20th-century avant-garde movements such as Dadaism and Futurism. These movements were characterized by their rebellious nature and their intent to break free from the constraints of traditional art forms. The Dadaists, for example, held public performances that incorporated absurdist poetry, nonsensical dialogue, and spontaneous actions, aiming to disrupt and critique the rationalism and nationalism that they believed had led to World War I.
