Definition
Sundown towns are U.S. towns and counties that excluded Black residents and visitors after sunset, enforced through some combination of local ordinance, signage at the city limits, restrictive housing covenants, real-estate practice, and the threat or use of violence.
The historian James W. Loewen, who coined the term as a category in Sundown Towns: A Hidden Dimension of American Racism (2005), documented several thousand such towns across the U.S., most of them outside the South — concentrated in the Midwest, the Mountain West, and California — and most of them established between roughly 1890 and 1940.
Why it matters
How it works
The label "sundown town" comes from signs that some such towns posted at their city limits — most commonly with a slogan along the lines of "Don't let the sun set on you, [N-word], in [town name]." Signs were never universal; many towns enforced the rule by reputation and police practice without ever needing to post it. Loewen's research, based on census records, oral histories, and local archives, identified towns by demographic pattern: places that had a substantial Black population in 1890 or 1910 and then suddenly had nearly zero a decade or two later.
The mechanisms of expulsion and exclusion varied. In some cases — Forsyth County, Georgia in 1912; Pierce City, Missouri in 1901 — a single triggering incident, usually an accusation against a Black resident, led to a mob driving the entire Black community out of the county and burning their homes. The expelled population never returned. In other cases the process was procedural: local real-estate agents refused to sell or rent to Black families; landlords refused to renew leases; restrictive covenants attached to deeds; school district lines avoided integration; police arrested Black travelers found in the town after dark.
The enforcement mechanism, where overt force was needed, was indistinguishable from lynching-era Southern racial violence: beatings, arsons, sometimes killings, almost never prosecuted. The implicit threat policed the boundary even when explicit force was not applied. A Black traveler in 1955 driving from Atlanta to Detroit faced a route on which dozens of towns were sundown towns, and the Green Book — Victor Hugo Green's annual travel guide for Black motorists — was a survival document, not a tourist recommendation.
Sundown towns began to break down only after the 1968 Fair Housing Act, and only slowly; many remained de facto sundown towns into the 1970s and beyond. Their imprint on contemporary demographic geography — small towns and rural counties that are virtually all-white in regions where larger nearby cities are substantially Black — is one of the clearest examples of how legal change does not, by itself, undo a hundred years of structural exclusion.
