An art movement is a style or trend in art that is characterized by a shared philosophy, techniques, or themes among a group of artists. These movements often emerge in response to social, political, or cultural changes and can span various forms of art, including painting, sculpture, and photography. Examples of well-known art movements include Impressionism, Cubism, and Surrealism. Artists within a movement typically influence each other and contribute to a collective identity. Movements can be short-lived or last for decades, and they often lead to new styles and ideas in the art world. Understanding these movements helps to contextualize the evolution of art throughout history.
