Many new states entered the United States around 200 years ago, but only Missouri almost killed the nation it was trying to join. When the House of Representatives passed the Tallmadge Amendment banning slavery from the prospective new state in February 1819, it set off a two-year political crisis in which growing northern antislavery sentiment confronted the aggressive westward expansion of the peculiar institution by southerners. The Missouri Crisis divided the U.S. into slave and free states for the first time and crystallized many of the arguments and conflicts that would later be settled violently during the Civil War. The episode was, as Thomas Jefferson put it, “a fire bell in the night” that terrified him as the possible “knell of the Union.”

Drawn from the of participants in two landmark conferences held at the University of Missouri and the City University of New York, those who contributed original essays to this second of two volumes—a group that includes young scholars and foremost authorities in the field—answer the Missouri “Question,” in bold fashion, challenging assumptions both old and new in the long historiography by approaching the event on its own terms, rather than as the inevitable sequel of the flawed founding of the republic or a prequel to its near destruction.
