In the first half of the 19th century, this area was developed as cotton
plantations, part of what was considered the
Mississippi Delta extending north to Memphis and south to Vicksburg. It depended on
slave labor. After emancipation, many African Americans continued to work in agriculture in this area. In the early decades of the 20th century, thousands of African Americans migrated north from Mississippi to
Chicago and other industrial cities in the
Great Migration to leave the violence and oppression of the South, as well as the loss of jobs due to mechanization of agriculture. Population also declined in the county as railroads and highways drew off traffic from the river. After 1995, gambling casinos and resorts were developed in the unincorporated community of Robinsonville, north of the county seat of Tunica. In a nod to riverboat gambling, to comply with state law, the casinos are built on floating platforms in the
Mississippi River. Lacking the structure of an organized city or town, Tunica Resorts consists mainly of casinos and cotton fields, with few permanent residents living in the community. Tunica Resorts has ranked as high as the third-largest casino-gambling destination in the United States, as measured by gaming revenue, behind
Las Vegas, Nevada and
Atlantic City, New Jersey. Its casinos attract gamblers mainly from nearby
Memphis, but also draw visitors from
Mississippi,
Tennessee,
Arkansas,
Alabama,
Missouri,
Georgia,
Illinois and
Kentucky. In the second decade of the 21st century, due to increased legalization of gambling in other states, including on Native American reservations, Tunica places sixth in gaming revenue, after the Las Vegas Strip, Atlantic City,
Chicago,
Connecticut, and
Detroit. The
2011 Mississippi River floods damaged casino resort buildings and infrastructure in this community. While the casinos float and escaped most damage, the hotels' towers and surrounding businesses are on land. Some of the hotels had major flooding on the lower floors, including the
Harrah's Casino Tunica, which was under nearly six feet of water. ==Economy==
