An influential visual arts design style that first appeared in France after World War I and began flourishing internationally in the 1920s, 1930s and 1940s before its popularity waned after World War II. It is an eclectic style that combines traditional craft motifs with Machine Age imagery and materials. The style is often characterised by rich colours, bold geometric shapes and lavish ornamentation.

Deco emerged from the interwar period when rapid industrialisation was transforming culture and was influenced by Cubism, Constructivism, Functionalism, Modernism and Futurism. One of its major attributes is an embrace of technology and distinguishes Deco from the organic motifs favoured by its predecessor Art Nouveau. It typically favours rectilinear rather than curvilinear forms.

During its heyday, Art Deco represented luxury, glamour, exuberance and faith in social and technological progress.

Significant figures include architect Le Corbusier.
