The Civil War broke out between 1861-1865 between the Union states of the North and the Confederate states of the South. Slavery was a central issue driving tensions between the states. Both armies consisted of white male soldiers between ages 18-45, though younger boys also served. The Union later allowed black soldiers, and some women disguised themselves as men to serve. Most Confederate soldiers were farmers, and the South focused more on agriculture than industry. Religion played an important role for both sides, with chaplains appointed and religious groups providing support.
