Union and States’ Rights…delivers a rare treat for American historians: thoughtful considerations on the abstruse but important ideas of interposition, nullification, and secession by leading constitutional scholars. Any historian who would like to have a thoughtful answer for the perennial student questions relating to states’ rights and southern history—Was secession constitutional in 1861? Is nullification legal today? What did the Founders think of interposition? and so on—will do well to consult Union and States’ Rights. Every essay brings forth interesting observations, startling facts, and greater understanding of the three states’ rights ghosts that have haunted the Union since 1787.
