Cubism was a revolutionary style of modern art developed by Pablo Picasso and Georges Braque in the early 20th century. It was the first style of abstract art and attempted to revitalize traditional Western art by developing a new way of representing subjects through analyzing them from multiple viewpoints within a geometric framework. Cubism had two phases - Analytic Cubism featured fragmented and monochrome images, while Synthetic Cubism introduced color and collage, moving towards a more decorative style.
