Answer
The **Letterist Faction**, founded by Guy Debord, played a crucial role in the development of avant-garde art, laying the groundwork for the Situationist movement. Rooted in Dadaist and Surrealist traditions, the Letterists experimented with détournement, a technique involving the subversion and recontextualization of existing cultural artifacts. Their goal was to critique society's conventions, challenge dominant narratives, and encourage revolutionary thought through unconventional artistic methods.
