He was right.
President Abraham Lincoln spent a good portion of his 1861 inaugural address on the issue of secession. That part of his speech took the form of a detailed legal brief denying the constitutionality of secession. His words dovetailed the illegality of secession with his oath as president to hold, occupy and posses the property and places belonging to the US government. He equated secession with anarchy.
The overwhelming issue in 1860 and 1861 was slavery and later the secession of several Southern states.
Breckinridge's stance on the issue of slavery differed from Lincoln's because Lincoln opposed the expansion of slavery into the territories and Breckinridge insisted that the government be required to protect slavery in any territory.
The election of Lincoln as the first Republican president, after the Democratic Party had split into two factions. Lincoln had been elected because he was moderate on the slavery issue.
In the election of 1856, what was noteworthy was the fact the issue of slavery was not discussed during the presidential campaign in a divided nation on this issue. James Buchanan and John Fremont were the main candidates. James Buchanan won the election, but he did not get the majority of the popular vote. Four years later, Lincoln would become president.
The most prominent person in the North who believed that secession was unconstitutional was President Lincoln. He was in step with many other Northerners.As an aside, the Confederate constitution sought to clarify this issue for its own states. Confederate states were not legally allowed to secede form the Confederacy as a clause within their constitution forbid secession.
He refused to take an oath to the Confederate States of America, was removed from office as the Governor and refused an offer from Presiident Lincoln of 50,000 US troops.
James Buchanan served as the 15th President of the United States from 1857 to 1861. Some notable events during his presidency include the Dred Scott Supreme Court decision, the financial Panic of 1857, and the secession crisis that eventually led to the American Civil War. Buchanan is often criticized for his inability to prevent the escalating tensions between the North and South over slavery, and for his passive stance on the issue.
