Art Nouveau was an artistic movement that began in the late 19th century and appeared across Europe. It sought to modernize design and move away from historical styles. Art Nouveau featured natural, flowing forms and organic motifs inspired by nature. It was most prominent in furniture design, which took on the styles of different European countries like France, Belgium, Austria, and Germany. Famous Art Nouveau designers included Henry van de Velde, Émile Gallé, and Louis Majorelle, who are known for their ornate yet functional furniture incorporating curved lines and nature-inspired decorations. Art Nouveau went out of fashion in the 1920s but saw a revival in popularity in the 1960s.
