Team X (or Team 10) was a group of architects assembled after World War II. Several personalities have been members of it throughout the years: Alison and Peter Smithson, Giancarlo De Carlo, Aldo Van Eyck. World War II was a truly global conflict with many facets: immense human suffering, fierce indoctrinations, and the use of new, extremely devastating weapons like the atom bomb World War II, also known as the Second World War, was by far the bloodiest, most expensive, and most significant war in... English architects Alison Smithson (1928-1993) and Peter Smithson (18 September 1923-3 March 2003) together formed an architectural partnership, and are often associated with the Brutalist style. ...

In 1950, following the Second World War (1939-45), some younger C.I.A.M. members envisioned other ways of considering the role of building within the context of urban design. They established themselves as Team X (Ten), but now independent of C.I.A.M., and with a new agenda. Team X argued for a fresh appreciation of architecture in general, and particularly within the social life of cities, in light of the destructive war years and the monumental task of rebuilding European cities. The Congrès International dArchitecture Moderne or CIAM (French for International Congress of Modern Architecture) was the think tank of the Modern Movement (or International Style) in architecture founded by a group of European architects led by Le Corbusier in 1928. ...

Team X members, other architects, and professionals of different callings, world wide, shared a vision of architecture and the city that they articulated through designs, publications, and teaching. The discourse in Modernist architecture shifted, and one might say, a new paradigm emerged.

A critical aspect of this shift was the recognition that architecture and urban design are team tasks; that the architect's primary client, even in the execution of the individual project, ultimately, was society itself. Architectural practice was reconsidered and colleagues with special knowledge called upon.
