" The idea that the South fought a war so that it could be left in peace to have slavery merely within its settled boundaries is sometimes voiced as a cherished myth today, but it does not fit the facts on the ground, nor did anyone think so at the time. Quite the contrary: the war was fought over the expansion of slavery. Southern rulers feared being restricted to the boundaries they then occupied. The dysfunctional-from-the-beginning Confederate States of America was set to have an aggressively annexationist foreign policy. "
