Related documents: [0]  [DOC] The Mississippi Delta is the distinctive northwest section of the U.S. state of Mississippi which lies between the Mississippi and Yazoo Rivers. The region has been called "The Most Southern Place on Earth" ("Southern" in the sense of "characteristic of its region, the American South"), because of its unique racial, cultural, and economic history. It is 200 miles long and 87 miles across at its widest point, encompassing circa 4,415,000 acres, or, some 7,000 square miles of alluvial floodplain. Originally covered in hardwood forest across the bottomlands, it was developed as one of the richest cotton-growing areas in the nation before the American Civil War (1861-1865). The region attracted many speculators who developed land along the riverfronts for cotton plantations; they became wealthy planters dependent on the labor of black slaves, who comprised the vast majority of the population in these counties well before the Civil War, often twice the number of whites.
