When did impressionism as a movement begin to fade out as an intellectual school?

Impressionism began to fade as a dominant intellectual school in the late 19th century, particularly after the 1880s, as artists sought new styles and movements, such as Post-Impressionism and Symbolism. The transition was marked by a shift toward more abstract and expressive forms of art. By the early 20th century, Impressionism had largely been integrated into the broader narrative of modern art, influencing subsequent movements while no longer being seen as a distinct intellectual school.
