On November 13, 1940, the Supreme Court ruled on Hansberry v. Lee, deciding that African Americans could not be prohibited from white neighborhoods.
In 1937, Carl Hansberry bought a property in Woodlawn, a predominantly white neighborhood in Chicago, that had a housing covenant outlawing black residents.
Shortly after purchasing the property Anna M. Lee filed a lawsuit against Hansberry. After a three year legal battle, which included a trip to the Illinois Supreme Court, a ruling was finally reached in favor of Hansberry.
The Hansberry v. Lee ruling paved the way for racially motivated housing covenants to be outlawed in the city of Chicago.
