Spring 1927: Perhaps America’s greatest natural disaster deeply changes race relations, government and society in the Mississippi River Valley. A flood of more than 30 feet of water stands over land inhabited by nearly one million people. Almost 300,000 African-Americans are forced to live in refugee camps for months. The changes produced by the flood in the lower South ultimately foreshadow federal government intervention in the region's social and economic life. Today, many draw parallels between Hurricane Katrina and the 1927 flood.
