As the one sovereign power, which makes, and therefore unmakes, Constitutions and Governments, resides in each State; so each State had the right to secede from the Federal Government. As each State, however, only made or adopted that Government for itself; so she could unmake it as to herself only. That is, she had no power to destroy the Federal Union, but only to withdraw from it, and let it move on in its own sphere. In the exercise of her original, inherent, indivisible, and alienable sovereignty, she merely seceded from the Union to which she had acceded, and asked to be let alone.
