Centered in Western Europe, this decorative arts movement began as an opposition to the historical emphasis in mid-19th century art. The movement was established as the first new decorative style of the 20th century at the 1900 World's Fair in Paris. Meaning New Art, Art Nouveau's decorative style and dedication to natural forms was internationally popular from 1880 to 1910. The movement had basis in Romanticism, Symbolism, and the British Arts and Crafts movement, notably the work of William Morris. With its origin in London, the movement spread throughout Europe and the United States and came to be called Jugendstil in Germany, Sezessionstil in Austria, and Modernismo in Spain. Art Nouveau had unique identities in each country, which sometimes created opposition between the varying nations and artists.
