Cubism was art artistic movement of the early 20th century. It began with the collaboration and partnership between Georges Braque and Pablo Picasso in Paris. around 1907. They got together after seeing the work of Paul Cezanne. This was tempered by the influence of African Art and the work of Henri Matisse. These various elements were then brought together in the piece "Les Demoiselles d'Avignon" by Picasso in 1907. This was widely seen as a sea change in the portrayal of natural objects from the western traditions of objectivity. This was taken a step further by Georges Braqu in 1908 with his exhibition in Paris, after which the term "Cubism" was used more generally.
