Cubism was a style of art that wanted to change how the eye could look at a piece of art by changing the perspective of painting.
Cubism is an abstract style that came about because of sudden changes in society at the beginning of the 20th century. Artists believed that the traditions of art were bland, and perspective was changed as a result. Cubists made the observer see things from different angles and heights, which explains the abstract look of the art. From different angles, the technique makes sense to the viewer.
Unprecedented growth in the late 1800s and early 1900s changed all kinds of areas of life. Still, it was challenging to show modernity 
with old traditions of art. Picasso and Braque created Cubism around 1907 in Paris. They were inspired by Paul Cézanne’s work.
A picture with a fixed position was not enough for cubists who wanted to experiment with the geometry of perspective. ‘Relativity’ made the artist and observer select images to interpret a subject on display. People could change their viewpoint and look at objects differently. This could add extra layers of emotion or memory to an image.
Cubism was revolutionary and attempted to ground art in a more realistic way of interpreting images with the eye for the modern world.
