Cubism developed in two stages between 1907-1914: Analytic Cubism and Synthetic Cubism. Analytic Cubism shattered objects into geometric forms and removed color, while Synthetic Cubism reintroduced color through techniques like papier collé and collage. The main Cubist artists were Pablo Picasso and Georges Braque, who depicted objects from multiple perspectives and blurred the lines between art and reality. They were influenced by Paul Cézanne's retrospective in 1907 and sought to represent 3D objects on a 2D surface in a new way.
