Cubism is an innovative art movement that emerged in the early 20th century, primarily associated with artists like Pablo Picasso and Georges Braque. It revolutionized the way objects and space were represented in art by breaking them down into geometric shapes and presenting multiple perspectives simultaneously. This style challenged traditional notions of perspective and form, leading to a fragmented and abstract representation of reality. Cubism laid the groundwork for various modern art movements and continues to influence artists today, making it a pivotal moment in the history of art.
