The whole Civil War was about political power, money, and destiny.
Political power...something that the South was losing rapidly, and the abolitionist North gaining by leaps and bounds.
Money...what the South stood to lose without their "peculiar institution".
Destiny...one people, one nation. The United States are vs. The United States is.
Requiem æternam dona eis, Domine; In memoria æterna erit justus, ab auditione mala non timebit.
Beauseant!
