The International Congresses of Modern Architecture (ICMA) were a series of influential meetings held between 1928 and 1959, aimed at discussing and promoting modern architecture. Organized by the Congrès Internationaux d'Architecture Moderne (CIAM), these congresses brought together architects, urban planners, and theorists to share ideas and establish principles for modern design. The first congress took place in La Sarraz, Switzerland, and set the stage for future gatherings. Key figures such as Le Corbusier and Walter Gropius participated, contributing to discussions on topics like urbanism, housing, and the role of architecture in society. These events significantly shaped modern architectural thought and practice.
