Stadterneuerung
Urban renewal, the redevelopment of areas within large cities, including white flight, has also been a factor in the growth patterns of African-American neighborhoods. The process began an intense phase in the late 1940s and continues in some places to the present day. It has had a major impact on the urban landscape. Urban renewal was extremely controversial because it involved the destruction of businesses, the relocation of people, and the use of eminent domain to reclaim private property for city-initiated development projects. The justifications often used for urban renewal include the "renewal" of residential slums and blighted commercial and industrial areas. In the second half of the 20th century, renewal often resulted in the creation of urban sprawl and vast areas of cities being demolished and replaced by freeways and expressways, housing projects, and vacant lots, some of which still remain vacant at the beginning of the 21st century. Urban renewal had a disproportionate and largely negative impact on African-American neighborhoods. In the 1960s James Baldwin famously dubbed urban renewal "Negro Removal".
