Sundown town

All-white municipalities that practice a form of racial segregation

Sundown towns, also known as sunset towns, gray towns, or sundowner towns, are all-white municipalities or neighborhoods in the United States. They are considered towns that practiced or still practice a form of racial segregation by excluding non-whites via some combination of discriminatory local laws, intimidation or violence. They were most prevalent before the 1950s. The term came into use because of signs that directed "colored people" to leave town by sundown.
