In the nineteenth and twentieth centuries the RIBA and its members had a leading part in the promotion of architectural education in the United Kingdom, including the establishment of the Architects' Registration Council of the United Kingdom (ARCUK) and the Board of Architectural Education under the Architects (Registration) Acts, 1931 to 1938. A member of the RIBA, Lionel Bailey Budden, then Associate Professor in the Liverpool University School of Architecture, had contributed the article on Architectural Education published in the fourteenth edition of the Encyclopædia Britannica (1929). His School, Liverpool, was one of the twenty schools named for the purpose of constituting the statutory Board of Architectural Education when the 1931 Act was passed.
