FThe Civil War was fought between the Northern and the Southern states from 1861-1865.

The American Civil War was fought between the United States of America and the Confederate States of America, a collection of eleven southern states that left the Union in 1860 and 1861. The conflict began primarily as a result of the long-standing disagreement over the institution of slavery. 

On February 9, 1861,  Jefferson Davis, a former U.S. Senator and Secretary of War, was elected President of the Confederate States of America by the members of the Confederate constitutional convention.  

After four bloody years of conflict, the United States defeated the Confederate States. In the end, the states that were in rebellion were readmitted to the United States, and the institution of slavery was abolished nation-wide.
