I used this website to gain an understanding of what Dadaism is. ( https://www.artyfactory.com/art_appreciation/art_movements/dadaism.htm )

According to wikipedia Dadaism was  an art movement of the European avant-garde in the early 20th century.   Also refereed to as ‘Dada’, it was a from of artistic anarchy born out of hatred for social, political and cultural values. It contained elements of art, music, poetry, theater, dance and politics. Dadaism was  was more of a protest movement rather than a style of art.

Dadaism was a very large movement during WW1 because many artists , writers and intellectuals what extremely opposed to the war. They used their art as a way of creating confrontation and provocation. Many traditional art movements were attacked. They launched a full scale ‘assault’ on the art world. “Dada questioned the value of all art and whether its existence was simply an indulgence of the bourgeoisie.” People involved with Dadaism claimed to be anti-artists.
