The answer to your question is "secede."
South Carolina
North Carolina did not "refuse to join the Union." The state joined the Union in 1789, becoming the 12th state to accede to the Constitution. The state attempted to leave the Union with a secession vote in 1861 because President Lincoln called upon the state to invade South Carolina, already a member of the Confederacy. The attempt to leave the Union failed as a result of Union military victory.
