Civil WAR 1861-1865
The American Civil War, a war fought between brothers, friends, countrymen. The question over a state's right to leave the union fostered by the horrific conditions and institution of slavery. More that 630,000 lives would be lost during those four years - not just in battle, but disease, infected wounds and starvation played their roles.
It is difficult to imagine sometimes why people would fight over such seemingly trivial things, but then, they - if looking at us, might ask the same thing. Or, they might wonder why we aren't more "up in arms" over issues of today.
Different times means different value systems and ideologies.
