Art Nouveau is an international movement and style of art, architecture and applied art-especially the decorative arts-that peaked in popularity at the turn of the 20th century (1890-1905). The name 'Art nouveau' is French for 'new art'. It is also known as Jugendstil, German for 'youth style', named after the magazine Jugend, which promoted it, and in Italy, Stile Liberty from the department store in London, Liberty & Co., which popularized the style. A reaction to academic art of the 19th century, it is characterized by organic, especially floral and other plant-inspired motifs, as well as highly-stylized, flowing curvilinear forms. Art Nouveau is an approach to design according to which artists should work on everything from architecture to furniture, making art part of everyday life.

The movement was strongly influenced by Czech artist Alphonse Mucha, when Mucha produced a lithographed poster, which appeared on 1 January 1895 in the streets of Paris as an advertisement for the play Gismonda by Victorien Sardou, starring Sarah Bernhardt. It was an overnight sensation, and announced the new artistic style and its creator to the citizens of Paris. Initially called the Style Mucha, (Mucha Style), this soon became known as Art Nouveau.
