Art movements are periods in art history characterized by a shared style, philosophy, or approach among artists. These movements often arise in response to social, political, or technological changes and can influence various forms of art, including painting, sculpture, and architecture. Examples of well-known art movements include Impressionism, Cubism, and Surrealism. Each art movement typically features distinct techniques and themes that reflect the artists' intentions and the cultural context of the time. For instance, Impressionism focused on capturing light and everyday scenes, while Cubism broke objects into geometric shapes. Understanding these movements helps us appreciate the evolution of artistic expression.
