<P> The City Beautiful Movement was a reform philosophy of North American architecture and urban planning that flourished during the 1890s and 1900s with the intent of introducing beautification and monumental grandeur in cities . The movement, which was originally associated mainly with Chicago, Cleveland, Detroit, and Washington, D.C., promoted beauty not only for its own sake, but also to create moral and civic virtue among urban populations . Advocates of the philosophy believed that such beautification could promote a harmonious social order that would increase the quality of life, while critics would complain that the movement was overly concerned with aesthetics at the expense of social reform; Jane Jacobs referred to the movement as an "architectural design cult ." </P> <P> The movement began in the United States in response to crowding in tenement districts, a consequence of high birth rates, increased immigration and internal migration of rural populations into cities . The movement flourished for several decades, and in addition to the construction of monuments, it also achieved great influence in urban planning that endured throughout the 20th century, in particular in regard to the later creation of housing projects in the United States . The "Garden City" movement in Britain influenced the contemporary planning of some newer suburbs of London, and there was cross-influence between the two aesthetics, one based in formal garden plans and urbanization schemes and the other, with its "semi-detached villas" evoking a more rural atmosphere . </P>
