Modernism is an early 20th-century movement in literature, visual arts and music, that emphasized experimentation, abstraction and subjective experience. Philosophy, politics and social issues were also aspects of the movement which sought to change how 'human beings in a society interact and live together'. The modernist movement emerged during the late 19th century in response to significant changes in Western culture, including secularization and the growing influence of science. It is characterized as a rejection of tradition and a hunt for newer, more original means of cultural expression. Modernism was influenced by widespread technological innovation, industrialization and urbanization, as well as cultural and geopolitical shifts that occurred after World War I. Artistic movements and techniques associated with modernism include abstract art, stream of consciousness in literature, cinematic montage, atonal and twelve-tone music and modernist architecture and urban planning.

Urban planning, also known as town planning, city planning, regional planning, or rural planning in specific contexts, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks, and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom lines that focus on planning as a tool to improve the health and well-being of people, maintaining sustainability standards. Similarly, in the early 21st century, Jane Jacobs's writings on legal and political perspectives to emphasize the interests of residents, businesses and communities effectively influenced urban planners to take into broader consideration of resident experiences and needs while planning.
