The image is an example of urbanization.
The image of the business district of Chicago in 1898 illustrates the architectural and urban planning developments during that period, particularly related to Chicago's historical growth and spatial configuration within the context of urban sociological and geographical models.
This type of image serves as an example of historical urban development in the context of the United States. The description of the image indicates it might relate to several themes in urban planning and architecture, as well as to the history of Chicago itself.
From the late 19th century, Chicago became a significant case study due to its rapid expansion and the resulting architectural innovations, like the development of skyscrapers. The Chicago School of architecture refers to the groundbreaking design of commercial buildings that arose in Chicago in the 1880s and 1890s, characterized by limited ornamentation, large window areas, and the inclusion of new technologies like safety elevators and steel framing. However, historians have debated the use of the term 'Chicago School' because it might imply a more cohesive set of principles than what was objectively present.
On a broader scale, urban sociologists and geographers developed models to explain urban morphologies, many of which originated from studies in Chicago due to its explosive growth. These models, like the Concentric Zone Model and the Sector Model, were used to understand how different areas of the city, typically categorized by economic class and function, were distributed and developed.
The mention of Burnham's vision for Chicago also highlights the City Beautiful movement, which aimed to include ample green spaces in urban designs.
