Conceptual Art is an art movement that emerged in the 1960s, emphasizing the idea or concept behind the artwork over traditional aesthetic and material concerns. Artists in this movement often use various mediums, including text, installations, and performance, to convey their messages. The focus is on the thought process and the viewer's interpretation rather than the physical object itself. This approach challenges conventional definitions of art, encouraging audiences to engage with the underlying ideas. Notable Conceptual Artists include Sol LeWitt and Marcel Duchamp, who famously questioned the nature of art through works like Fountain, a urinal presented as art.
