| My reading of South Carolina's "Declaration of the Immediate Causes Which Induce and Justify the Secession of South Carolina from the Federal Union" says they believed otherwise. They seemed to regard abolition as no longer a fringe policy but one which, in the North, was effectively mainstream, and were certain that after Lincoln's inauguration the North would wage a war to exterminate slavery. > For twenty-five years this agitation has been steadily increasing, until it has now secured to its aid the power of the common Government. Observing the forms [emphasis in the original] of the Constitution, a sectional party has found within that Article establishing the Executive Department, the means of subverting the Constitution itself. A geographical line has been drawn across the Union, and all the States north of that line have united in the election of a man to the high office of President of the United States, whose opinions and purposes are hostile to slavery. He is to be entrusted with the administration of the common Government, because he has declared that "Government cannot endure permanently half slave, half free," and that the public mind must rest in the belief that slavery is in the course of ultimate extinction. ... > On the 4th day of March next, this party will take possession of the Government. It has announced that the South shall be excluded from the common territory, that the judicial tribunals shall be made sectional, and that a war must be waged against slavery until it shall cease throughout the United States. The Texans seemed to have similar viewpoints that the abolition of slavery was not a fringe policy, and would be carried out during the next administration: > By consolidating their strength, they have placed the slave-holding States in a hopeless minority in the federal congress, and rendered representation of no avail in protecting Southern rights against their exactions and encroachments. ... > And, finally, by the combined sectional vote of the seventeen non-slave-holding States, they have elected as president and vice-president of the whole confederacy two men whose chief claims to such high positions are their approval of these long continued wrongs, and their pledges to continue them to the final consummation of these schemes for the ruin of the slave-holding States. (I trust that "within the next administration" isn't what you mean by "indeterminate".) |
In the north and even in the Republican party itself immediate abolition without compensation was still certainly a 'fringe' view. However the new administration was pretty explicit about not allowing new slave states to join in the future while simultaneously allowing accept new free states.
Slave states would've been outvoted in Congress, which would've probably led to eventual abolition. However it would've been a slow and gradual process with possible compensation and much closer to a 'death by a thousand cuts' (anything else would've just triggered a secession and most northern politicians certainly preferred allowing the Southern states to maintain slavery for the foreseable future).
So I certainly doubt most reasonable people in the South expected that slavery would be abolished 'within the next administration,' but they still must have seen the writing on the wall and judged that they'll never be in a stronger position than they were at that time. When they actually decided to secede, it made sense to use the strongest/most outlandish language possible in their propaganda (since of course, there were still probably some people who might have believed it)
