South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, North Carolina, and Tennessee all seceded from the Union in that order.

Confederation
When Lincoln took office in March 1861 seven southern states had left the Union.
11 southern states left the union and formed a separate government.
Jefferson Davis
The "confederate" army.
The 7 states that left the union were the Confederate States of America, or the Confederacy. 4 additional states joined the first 7 to complete the Confederacy.
The Confederates were the Southern slave-states that had seceded from the USA. The Union (North) was what was left.
Because He did not know...
Richmond, Virginia
The southern states were Confederate states. The northern states were part of the Union. :)
The Southern states, who formed the Confederation.
