Art Nouveau was a decorative art movement that emerged in the late 19th century, characterized by its use of organic, flowing lines and stylized floral motifs. This style was applied across various media, from architecture to jewelry.

The movement sought to break away from historical styles, creating art that embraced modernity. Famous examples include Gustav Klimt's paintings and Antoni Gaudí's architectural works, which demonstrate the movement's emphasis on harmony between design and nature.
