Inspired by the works of Paul Cezanne (who is usually categorized as a Post-Impressionist), Cubism was founded by Pablo Picasso and Georges Braque. Picasso, in particular, would become associated with this particular form of art during his career.
Cubism represented a major development in the world of art. It dispensed with conventional perceptions offered through straight-ahead perspectives and involved, instead, a radically different way of approaching one's subject. Rather than the usual one-dimensional view of reality, Cubism involved a multidimensional perspective that also included geometric shapes and distorted imagery, as if viewing an object through a broken prism. Rather than offering a single vantage point, Cubism suggested several.
Because of its highly unconventional nature, Cubism had its share of detractors, just as had the Impressionists. It endured, however, and Picasso remains one of modern history's most critically successful painters.
