History and Evolution
The human history of the Southeast is ancient, with evidence of the Clovis culture dating back to approximately 11,000 BC or 13,000 BC. Before European contact, the region was home to Native Americans during the Woodland period.
European colonization began with Spanish conquistadors; Hernando de Soto crossed the Mississippi River in 1541, and Spain established St. Augustine, Florida, in 1565—the first permanent European settlement in the United States. Later, Georgia, North Carolina, South Carolina, and Virginia became part of the Thirteen Colonies that declared independence from Great Britain.
The region was central to the American Civil War, where the Confederate States of America included Florida, Alabama, Georgia, Mississippi, Tennessee, South Carolina, North Carolina, Virginia, Louisiana, and Arkansas. Following the war and the Reconstruction era of the 1870s, the region entered a period of segregation under Jim Crow laws, which lasted until the mid-1960s.
Economic modernization accelerated in the 1930s through New Deal policies, such as the Tennessee Valley Authority. World War II further shifted the economy from farming to military production. By the late 20th century, a warm climate and business-friendly environment attracted millions of retirees and job seekers, leading to explosive growth in states like Florida, Georgia, and North Carolina.
