Art Nouveau was an artistic style prominent from 1890 to World War 1 that drew inspiration from natural forms like plants and flowers. It included architecture, interior design, graphics, fine arts, and decorative arts. Key features included curved lines, flat decorative patterns, and rejection of earlier styles. Art Nouveau had many regional names across Europe and the United States. Architecture featured curved glass, plant-like embellishments, and asymmetrical shapes. Graphics played a key role through techniques like lithography, posters, and magazines. Glass art, sculpture, jewelry, and ceramics also expressed the style through nature-inspired designs and new materials.
