Coming out of the early twentieth century, Cubism was created by Pablo Picasso, and Georges Braque. Cubist painters rejected the concept that art should copy nature and the traditional techniques of perspective, modeling, and foreshadowing. Emphasizing two dimensional canvas, they reduced and fractured objects into geometric forms, and used multiple or contrasting vantage points. Cubism is characterized as figures and objects being shattered and then reassembled. The most famous cubist, Pablo Picasso was influenced by the Spanish-Civil war. Cubism paved the way for geometric abstract art by introducing new concepts.
