Liberty Ships, Closed Doors

The home-front migrations that remade America. When World War II turned the United States into the Arsenal of Democracy, it set the largest internal migration in the nation's history in motion — and cracked open the industrial workforce for Black Southerners, women, and others long shut out, even as it forced some groups out entirely and tried to close the doors again when the war ended. A ReThink History series, told evenhandedly and grounded in the record, that follows every group the boom moved — and comes home to one shipyard town: Marinship, Marin City, and Sausalito. Narrated by AI voices from sourced, human-reviewed research.
