The American Civil War made a huge impact on Tennessee, with large armies constantly destroying its rich farmland, and every county witnessing combat. It was a divided state, with the Eastern counties harboring pro-Union sentiment throughout the conflict, and it was the last state to officially secede from the Union, in protest of President Lincoln's April 15 Proclamation calling forth 75,000 members of state militias to suppress the rebellion. Although Tennessee provided a large number of troops for the Confederacy, it would also provide more soldiers for the Union Army than any other state within the Confederacy.
