I heard about this on the Weather Channel. I guess it's a liberal station too? Great Mississippi Flood of 1927 - Wikipedia, the free encyclopedia Great Mississippi Flood of 1927 During the disaster, 700,000 people were displaced, including 330,000 African-Americans who were moved to 154 relief camps. Over 13,000 evacuees near Greenville, Mississippi, were gathered from area farms and evacuated to the crest of an unbroken levee, and stranded there for days without food or clean water, while boats arrived to evacuate white women and children. Many blacks were detained and forced to labor at gunpoint during flood relief efforts. Population was not recognized as requiring relief aid. Several reports on the terrible situation in the refugee camps, including one by the Colored Advisory Commission by Robert Russa Moton, were kept out of the media at the request of Herbert Hoover, with the promise of further reforms for blacks after the presidential election. When he failed to keep the promise, Moton and other influential African-Americans helped to shift the allegiance of Black Americans from the Republican party to Franklin Delano Roosevelt and the Democrats.
