The fifteenth and sixteenth states to join the United States of America, Kentucky and Tennessee were cut from a common cloth -- the rich region of the Ohio River Valley. Abounding with mountainous regions and fertile farmlands, these two slaveholding states were as closely tied to one another, both culturally and economically, as they were to the rest of the South. Yet when the Civil War erupted, Tennessee chose to secede while Kentucky remained part of the Union. The residents of Kentucky and Tennessee felt the full impact of the fighting as warring armies crossed back and forth across their borders. Due to Kentucky's strategic location, both the Union and the Confederacy sought to control it throughout the war, while Tennessee was second only to Virginia in the number of battles fought on its soil.
