President Jefferson Davis.
The election of Abraham Lincoln in November 1860.
Abraham Lincoln faced the secession crisis that erupted into the Civil War.
Lincoln viewed secession as a constitutional crisis that threatened the Union, believing that states did not have the right to unilaterally withdraw from it. Conversely, Robert E. Lee recognized secession as a states' right but regarded it as an act of anarchy that undermined the nation’s unity. While both men acknowledged the concept of states' rights, their interpretations led them to fundamentally different conclusions about the legitimacy and consequences of secession.
Bay of Pigs invasion and the Cuban Missile Crisis.
A good number of Lincoln biographers have betrayed President elect Lincoln as being isolated in Springfield Illinois as the secession crisis unfolded after his November 1860 election victory. Many believe that he did not understand the depth of the problem or saw the secession process as a bluff to extort concessions such as the extension of the Missouri Compromise line west to the Pacific coast. What most historians seem to agree on is that it would have been impossible to persuade the Deep South to renounce their secession.
The president most likely to support the secession of the Southern states from the Union would be John C. Calhoun, who served as Vice President and was a strong proponent of states' rights and nullification. While not a president himself, his political ideology aligned closely with the interests of Southern states seeking to secede. Among actual presidents, Andrew Johnson, who succeeded Abraham Lincoln, had a more lenient approach to Reconstruction and might have been more sympathetic to Southern grievances. However, it is important to note that no president openly supported secession, as it was a constitutional crisis.

In the end, SC was forced to comply with the law and it became established the Federal Government was in charge. - The secession of the Confederate States. The Constitution had been silent on whether this was allowed. Of course, it triggered a civil war. Since the Unionists won the war, it is now accepted that secession isn't possible. - The 1876 Presidential election.
