Minimalism emerged in the 1960s as a reaction against abstract expressionism. Minimalist artists aimed to eliminate composition from their work and create purely visual, non-representational pieces. Key minimalist artists included Frank Stella, Sol LeWitt, Donald Judd, and Dan Flavin. They used industrial materials and geometric forms to create ordered and simplistic sculptures and installations. Their goal was for the works to be seen as literal objects rather than symbolic representations.
