Confederate States of America The Confederate States of America (CSA or C.S.), commonly referred to as the Confederacy, was an unrecognized country in North America that existed from 1861 to 1865. The Confederacy was originally formed by seven secessionist slave-holding states – South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas – in the Lower South region of the United States whose regional economy was mostly dependent upon agriculture, particularly cotton, and a plantation system that relied upon the labor of African-American slaves.
Southern Unionist In the United States, Southern Unionists were white people living in the Confederate States of America, opposed to secession, and against the Civil War. These people are also referred to as Southern Loyalists, Union Loyalists and Lincoln Loyalists. Pro-Confederates in the South derided them as Tories. During reconstruction these terms were replaced by "scalawag", which covered all Southern whites who supported the Republican Party. Tennessee, North Carolina, and Virginia (which included West Virginia at that time) were home to the largest populations of loyalists, thousands of whom volunteered for Union military service.
