Mississippi is a U.S. state in the South. Mississippi is named for the Mississippi River, which separates it from Louisiana and Arkansas to the west. To the east lies Alabama, and to the north Tennessee. Mississippi was one of the richest places in the world before the American Civil War due to the cotton industry; Natchez, Mississippi had more millionaires per capita than anywhere else. However, the Civil War and subsequent abolition of slavery took its toll on Mississippi's economy, and today it is one of the poorest states. Mississippi's capital and largest city is Jackson.
