Dadaism arose during and after World War I, reflecting the disillusionment and skepticism prevalent in the aftermath of the war.

Readymades were everyday objects, such as urinals or bottle racks, that Dadaists selected and presented as art, challenging traditional notions of artistic value.

Duchamp's 'Fountain' was originally a porcelain urinal that he signed and submitted to an art exhibition, sparking controversy and challenging conventional ideas of what constitutes art.

Collage in Dadaism was employed to combine unrelated images, objects, and texts, creating unexpected and often nonsensical juxtapositions that challenged conventional notions of artistic coherence.

Dadaists used public demonstrations and performances as a means of disrupting conventional expectations and provoking reactions, often satirizing social and cultural norms.

Dadaists criticized the art market for its focus on monetary value, its elitist tendencies, and its transformation of art into a commodity.

Dadaists believed that the art market had become driven by financial motives, prioritizing profit over artistic value and creativity.

Dadaists employed various satirical strategies to critique the art market, including creating nonsensical artworks, selling fake or worthless items as art, and holding exhibitions in unconventional venues.

Dadaists critiqued various aspects of modern society, including consumerism, industrialization, urbanization, and political and social institutions, seeing them as dehumanizing and alienating.

Dadaism's unconventional practices and critical stance towards the art market and commercialism influenced the development of subsequent art movements, including Surrealism, Pop Art, Abstract Expressionism, Minimalism, Conceptual Art, and Performance Art.

Marcel Duchamp created the 'L.H.O.O.Q.' artwork, which consisted of a mustache and goatee drawn on a reproduction of Leonardo da Vinci's 'Mona Lisa'.

Dadaists used photomontage to combine multiple photographs, manipulate and alter images, and incorporate photographs into other artistic media.

Dadaists organized 'happenings' or 'events' that were spontaneous, often chaotic performances, challenging conventional notions of artistic presentation.

Dadaism's critique of the art market and commercialism led to the emergence of the concept of the readymade, where everyday objects were elevated to the status of art.

Jeff Koons is known for his use of everyday objects and mass-produced items in his sculptures and installations, which reflects the influence of Dadaism's critique of the art market and commercialism.
