Cubism emerged in France in the early 1900s led by Picasso and Braque who were influenced by Cezanne's geometric breakdown of forms. They depicted objects from multiple perspectives simultaneously on canvas. This analytical cubism gave way to synthetic cubism where collage elements were incorporated. Other notable cubists included Gris, Delaunay, Leger, and Duchamp. While revolutionary, cubism was highly controversial as it broke conventions and its abstract forms were difficult for audiences to understand. Over time it had a massive influence on modern art.
