Conceptual art emerged in the 1960s as an art movement focused on conveying ideas rather than creating traditional art objects. It was influenced by Marcel Duchamp's "readymades" and intended to challenge notions of what art could be. Key aspects of conceptual art include prioritizing concepts over physical works and questioning relationships between art, artists, and audiences. Pioneering conceptual artists included Joseph Kosuth, Sol LeWitt, Lawrence Weiner, and members of the influential Art & Language group.
