Question:

What did southern states feel they have the right to do in civil war?

The concept of states' rights had been an old idea by 1860. The original thirteen colonies in America in the 1700's separated from the mother country in Europe by a vast ocean, were use to making many of their own decisions and ignoring quite a few of the rules imposed on them from abroad. During the American Revolution, the founding fathers were forced to compromise with the states to ensure ratification of the Constitution and the establishment of a united country. In fact, the original Constitution banned slavery, but Virginia would not accept it; and Massachusetts would not ratify the document without a Bill of Rights.
