Art Deco was an artistic style that began in Paris in the 1920s and flourished internationally in the interwar period. It was a reaction against the organic forms of Art Nouveau and embraced geometric shapes, machine aesthetics, and new materials. Art Deco emphasized symmetry, straight lines and sharp angles rather than the flowing asymmetry of Art Nouveau. It featured motifs like chevrons, zigzags and sunbursts and was characterized by bold colors and lavish ornamentation representing luxury and modernity. The 1925 Paris Exposition helped establish Art Deco as a global style that influenced architecture, design and the visual arts.
