The City Beautiful Movement was an urban planning initiative that emerged in the late 19th and early 20th centuries in the United States. It aimed to improve the aesthetic appeal of cities through the design of beautiful public spaces, parks, and monumental architecture. Influenced by the World's Columbian Exposition of 1893 in Chicago, the movement sought to promote civic pride and social order by creating harmonious urban environments. Key figures in the movement included architects like Daniel Burnham and Frederick Law Olmsted, who emphasized the importance of integrating nature into urban settings. The movement led to the development of iconic urban parks and the establishment of city planning commissions, ultimately influencing modern urban design principles and the creation of more livable cities.
