A sundown or sunset town was a town, city, or neighborhood in the US that excluded non-whites after dark.

The term sundown came from the signs that were posted stating that people of color had to leave the town by sundown.

A THREAD! Image
In most cases, signs were placed at the town's borders which read: “Stranger/Negro, Don't Let the Sun Set On You Here." The exclusion was official town policy or through restrictive covenants agreed to by the real estate agents of the community. Image
The policy was usually enforced through intimidation. This intimidation could occur in a number of ways, including harassment by police officers or neighbors and in some circumstances violence.
