Pablo Picasso is primarily associated with the Cubism art movement, which he co-founded alongside Georges Braque in the early 20th century. This movement characterized its innovative approach to perspective and representation, fragmenting subjects into geometric shapes and interconnecting planes. Cubism challenged traditional notions of art, encouraging viewers to consider multiple viewpoints simultaneously. Picasso's works, such as "Les Demoiselles d'Avignon" and "Guernica," showcase the distinct qualities of this style. Beyond Cubism, Picasso also explored various other movements and techniques throughout his prolific career, leaving a lasting impact on modern art.
