They left the union to join the confedirety
Abraham Lincoln
Prior to the Civil War, the US Constitution did not prohibit states from seceding.
Yes, after the Civil War the United States government approved a amendment abolishing the right for a state to leave the Union.
I don't know if I'm right, but I'd say that they celebrated different states seceding from the Union.
The Southern States believed that they had the right to secede because the Union had violated the US Constitution. Because of this the Southern States believed that the Republican dominated Congress and the views of President elect Lincoln would continue to do so, thus the Southern States believed that they had the right to leave the Union.
They did have the right to leave the union, it says so in the constitution.
That is a matter of opinion.
There is no acceptable, legal process for seceding from the Union. In 1861, believing they had the legal right to secede, 7 states held votes of their legislatures and passed secession bills. The states notified the federal government that they were no longer in the Union. Later 4 other states joined the 7 Confederate states. The outgoing president, James Buchanan, stated that the secession was illegal but that he did not believe the government had a right to send military force to quell the breakaway movement. President Lincoln, upon taking office, received the justification for military action when South Carolina militia and military school students fired on Fort Sumter. The Union's military victory over the secessionists effectively eliminated the idea that states could decide to leave the Union.
Yes, many people thought that Jefferson Davis ought to have been hanged for treason.
In typesetting justify is used in connection with left, right and force. In a left justified paragraph each line of text is aligned on the left margin. Right justify has text aligned along the right margin. Force justify creates a paragraph aligned on both the left and right margins.
Most people today believe that Lincoln and his supporters were trying to abolish slavery by fighting a civil war. But if you go back to the real history, documents and letters, you will find out that they were keeping the southern states from seceding from the Union. This is a very debatable topic, seceding from the Union, Many say that is the southern states had left, England would have taken over North America. But if you review the US Constitution you will remember that it is the right of every state to seceding from the Union with out conflict. But because of Lincoln and his supporters, only Texas has that right today; well, as of right now. A great book to read is "A Century of war: Lincoln, Wilson & Roosevelt" by Denson
The Civil War was fought to establish that point.
