Congrès International d'Architecture Moderne

The Congrès internationaux d'architecture moderne (CIAM), or International Congresses of Modern Architecture, was an organization founded in 1928 and disbanded in 1959, responsible for a series of events and congresses arranged across Europe by the most prominent architects of the time, with the objective of spreading the principles of the Modern Movement focusing in all the main domains of architecture (such as landscape, urbanism, industrial design, and many others).

The International Congresses of Modern Architecture (CIAM) was founded in June 1928, at the Chateau de la Sarraz in Switzerland, by a group of 28 European architects organized by Le Corbusier, Hélène de Mandrot (owner of the castle), and Sigfried Giedion (the first secretary-general). CIAM was one of many 20th century manifestos meant to advance the cause of "architecture as a social art".

Other founder members included Karl Moser (first president), Hendrik Berlage, Victor Bourgeois, Pierre Chareau, Sven Markelius, Josef Frank, Gabriel Guevrekian, Max Ernst Haefeli, Hugo Häring, Arnold Höchel, Huib Hoste, Pierre Jeanneret (cousin of Le Corbusier), André Lurçat, Ernst May, Max Cetto, Fernando García Mercadal, Hannes Meyer, Werner M. Moser, Carlo Enrico Rava, Gerrit Rietveld, Alberto Sartoris, Hans Schmidt, Mart Stam, Rudolf Steiger, Szymon Syrkus, Henri-Robert Von der Mühll, and Juan de Zavala. The Soviet delegates were to be El Lissitzky, Nikolai Kolli and Moisei Ginzburg, although at the Sarraz conference they were unable to obtain visas.
