The International Coalition of Art Deco Societies (ICADS) is a voluntary alliance of societies from around the world which strive to inform and educate the public on the important contributions made by artists, designers and architects of this period. Members assist each other with support during battles for the preservation of architecture from the period. ICADS conducts a bi-annual World Congress on Art Deco in cities where a member society nominates itself as a host. The next World Congress will be held in Shanghai November 1-6, 2015.
