Why did Art Nouveau end?

Art Nouveau ended primarily due to world events. When World War I broke out in 1914, artistic production was largely halted in order to free up materials for manufacturing equipment for the war effort. By the time the 1919 Treaty of Versailles brought about the end of the war, interest in Art Nouveau had waned. Designers and artists became interested in new forms and styles, such as Art Deco.
