One riot, several causes
The Detroit riot began on Sunday 23 July 1967 and was a single event, not a series of riots, whatever the plural in the title may suggest. Its immediate trigger was a police raid, but historians generally look to longer-running conditions to explain why a raid on a single bar could lead to five days of disorder. Housing is one of the best documented of those conditions, because decisions by banks, governments, builders and homeowners shaped where Black Detroiters could live for decades.
Redlining and the color line
During the 1930s the federal Home Owners’ Loan Corporation drew maps rating neighborhoods for mortgage risk, and later federal housing agencies followed similar practices. Areas with Black residents were typically placed in the lowest category, shaded red. The Federal Housing Administration also favoured new suburban construction and, for years, supported racially restrictive covenants in its underwriting guidance. In practice, this meant that mortgage credit flowed to white buyers in new suburbs and was harder to obtain for Black buyers and for the older neighborhoods where they lived.
Private action reinforced policy. Real-estate agents steered buyers, neighborhood improvement associations enforced covenants, and white homeowners sometimes used harassment and violence to keep Black families out. A Detroit case from 1925 became famous: Dr. Ossian Sweet, a Black physician who moved into a white neighborhood, was tried after a shot from his house killed a man in a hostile crowd, and was defended by Clarence Darrow in a case that ended without a conviction. In 1948, in Shelley v. Kraemer, the Supreme Court ruled that courts could not enforce racial covenants, and a Detroit case was decided alongside it. The ruling ended the legal enforcement of covenants but not discrimination in practice.
Black Bottom and Paradise Valley
Detroit’s historic Black community was centered on the lower east side, in the neighborhood called Black Bottom and the commercial district known as Paradise Valley, with its businesses, churches, clubs and theaters. It was crowded and often poorly maintained, because owners had little reason to invest and residents had few other options, but it was also a dense and lively community.
In the 1950s and early 1960s the city used urban renewal powers to clear much of the area. A large part of it became the Lafayette Park residential development, and highway construction, including the Chrysler Freeway, cut through what remained. Thousands of residents were displaced, and many of them moved to other already crowded neighborhoods on the west side, such as the area around 12th Street, or to public housing. Many small businesses were lost. Critics at the time and later called the policy “Negro removal”, a phrase also used in other American cities. The expressways also improved suburban access to downtown, which further tilted the benefits of public investment.
Crowding and the 12th Street area
The west side of Detroit around 12th Street, where the riot began, had once been a mainly Jewish neighborhood and became increasingly Black in the 1950s and 1960s as white residents left. By 1967 many of its residents were renters, often paying high rents to absentee landlords for older, divided buildings. The neighborhood was dense and crowded, with a large share of young people and a modest level of business ownership by residents themselves. Not all parts of Black Detroit were poor, and the city had many stable, well-kept Black neighborhoods and homeowners, but the 12th Street area was among the most strained.
The segregated suburbs
Beyond the city’s borders the picture was different. As Detroit’s white population left for the suburbs in large numbers after the war, suburban municipalities used zoning, housing prices and, in some cases, informal pressure to remain overwhelmingly white. Black families often could not follow the jobs and schools that moved outward. The racial boundary at Eight Mile Road, the city’s northern edge, became a symbol of this division. In 1967 the metropolitan area was among the most segregated in the country, and the regional pattern left the city itself with a growing share of poor and Black residents.
What the Kerner Commission said
The Kerner Commission, appointed in the days after the riot, placed discrimination and segregation in housing near the center of its explanation of the disorders in cities like Detroit, along with poverty and policing. Its report in early 1968 called for large programs, including open housing. Congress passed the Fair Housing Act in April 1968, a week after the assassination of Martin Luther King Jr., though enforcement was weak at first. It followed the Civil Rights Act of 1964, which had not covered housing at all.
Limits of the argument
Housing explains a great deal, but not everything. Riots occurred in cities with different histories, and historians still debate how to weigh housing against employment, policing, and the national climate of 1967. What the Detroit example shows is that residential segregation was not natural or accidental. It was built through identifiable decisions, and by 1967 many residents saw the results as part of their daily lives. The white backlash against open housing that followed in the late 1960s showed how deeply the issue ran.
