How about during the War of 1812?
How about during the War of 1812?
One thing is certain, though: Abraham Lincoln would never allow the Union to be dissolved. If he's in the White House, there could be no peaceful secession.
You don't get peaceful secession with Jefferson Davis as Confederate President. Rather than try to solve things peaceably, Davis started the war by ordering the unprovoked attack on Ft Sumter.
Come, let's be realistic here. Lincoln had, by that point, made it absolutely clear that he was not going to let the South go. Fort Sumter was a very dumb move on the part of the South, absolutely, but did it cause the war? No. The war would've commenced anyway. Even if the South had been completely peaceful about it, secession was an unacceptable concept to Lincoln.
While I agree that a potato with a face painted on it would likely have made a better president than Davis, replacing him with anyone else will not prevent the war. For that to be possible, the general opinion held by the (leadership in the) North will have to be changed. That is: they must be willing to consider a scenario where secession is acceptable to them. To Lincoln, it was never going to be acceptable.
What would be the best POD for a peaceful Southern secession ?
Someone other than Lincoln getting the Republican nomination, perhaps? Or perhaps Stephen Douglas wins in 1860 one way or another (difficult but not impossible) and the first Republican isn't elected until 1864 and there have somehow been significant changes in the intervening four years to allow for a peaceful secession.
One thing is certain, though: Abraham Lincoln would never allow the Union to be dissolved. If he's in the White House, there could be no peaceful secession.
Eh, I disagree. Had the South not attacked the Fort, they might have been able to enter a period of "False / Fake" war which very well could have politically been to their advantage.
What about if James Buchanan had died for some reason, leaving his Kentuckian VP Brekinridge as president until March 4, 1861? OTL Brekinridge had advocated the withdrawal of federal forces from all Confederate states(such as Fort Sumter, for example) in the name of preventing a war. Assuming the military doesn't outright disobey a Brekinridge order to withdraw from the South, this would mean that Lincoln would have to order the first shot of a war.
Would he do it? Even if he did, he would not have the overwhelming support of the public and political class, which only rallied behind the war on account of the Fort Sumter attack. Assuming the war drags on like in OTL(if anything it's likely to go worse for the Union due to substantial/majority public opposition to the war) it's entirely plausible that the Democratic candidate in the 1864 election could run on and win on a platform of forging a truce with the Confederate States.
POD's.
1) I would go with the US constitution being clear that states are allowed to leave, with some formal mechanism such as a 2/3 vote for it in the state that wants to leave. Have this in the original 11 Amendments.
