Post-World War II art emerged as a response to the dramatic changes in society and culture following the war. Artists began to explore new styles and ideas, moving away from traditional forms. This period saw the rise of movements like Abstract Expressionism, where artists like Jackson Pollock used spontaneous techniques to express emotions and ideas. Another significant development was the emergence of Pop Art, which incorporated elements from popular culture, such as advertisements and comic strips. Artists like Andy Warhol challenged the boundaries of art by blurring the lines between high and low culture, making art more accessible to the public.
