Don’t let the sun set on you in a sundown town. That’s what signs at the city limits of all-white communities warned when African-Americans were not allowed to live there or even visit after the sun set. This method of exclusion was often held by an official policy or restrictive covenant-. The practice of excluding blacks from American towns was so prevalent that, by 1936, it became the impetus for Harlem civic leader Victor Green to pen the Negro Motorist Green-Book, a guide designed to help African-American travelers avoid places where they could be harassed, threatened, or even killed. Today, it is illegal for sundown towns to exist on paper due to the 1968 Fair Housing Act, but some believe that communities remain sundown by reputation and reluctance to diversify.
