The people who opposed secession believed that a state could not leave the union without permission form the remaining states, which had neither been sought nor given. The people supporting secession believed that each state had the right to leave the Union without need of permission from other states.
It was a state rights issue. The question was who could determine how the federal government could tell each state what to do.
The theory used by southerners to justify the secession of the southern states is that the states voluntarily entered into a union with each other, and should be able therefore to voluntarily withdraw from that union should they so desire, particularly since nothing in the US constitution states that the union is irrevocable.
The Dred Scott verdict - which appeared to mean that slavery was legal anywhere in the USA. The Lincoln-Douglas debates - won by Douglas, who said that each state should decide whether to be free or slave. The John Brown raid - which made the Abolitionists look like terrorists, and gave respectability to Southern slave-owners.
It depends on what you consider secession. North Carolina was the last state who's legislature approved an ordinance of secession (May 20, 1861). However, both Tennessee and Virginia submitted their articles of secession to the voters for approval, and these ratifications occurred later. Virginia voters approved secession on May 23, 1861, while Tennessee voters approved secession on June 8, 1861. So while Tennessee was the last state to "officially" secede, North Carolina was the last state to practically secede (as the voter ratifications were basically just a formality at that point).
the southern states wanted to govern their territories as they saw fit without any interference from the government.
What state? It's typically in the early fall but each state sets their dates.
The state website provides a list of Southern state parkway exits. The list can be downloaded and printed. The list will also have up to date information as to construction at each exit.
You mean the secession of the individual states that made up the Confederacy? The governors of each state, and then the Confederate cabinet under Jefferson Davis, who tried to enlist more states like Missouri and Kentucky.
The five Border States, though officially slave states, remained part of the Union. Each state handled the division in different ways. Delaware State house rejected secession overwhelmingly. While some held sympathy for the Confederacy, they were far away and really didn't identify with the southern states. While there was support for secession in Maryland, particularly Baltimore and some other areas, secession was rejected. Maryland provided troops for both the Union and the Confederacy. While Kentucky did not vote to secede, they passed a bill of neutrality, and asked both sides to stay out. When Confederate troops led by General Polk violated that neutrality, Kentucky decided to support General Ulysses S. Grant and ordered the confederates expelled. Missouri voted not to secede, but issued a formal statement of opposition to the Union's coercion of the southern states. West Virginia, then part of the state of Virginia considered secession treason and succeeded in splitting from the state when it chose to secede.
