In the 15 years leading up to the Civil War, a wide variety of theories emerged for how the federal government should deal with slavery expanding, or not expanding, into the territories acquired by the United States.

Both President John Quincy Adams and Henry Clay were of the mindset that much could be accomplished in developing the American economy with the help of the government. Martin Van Buren had different ideas, however.

Not long after the election of 1820, an essentially uncontested election seeing the re-election of President James Monroe, the campaigning for the election of 1824 began. President Monroe had indicated that he would not seek an unprecedented third term as president, but that did not stop others from posturing for the election. As a journalist observed in the spring of 1822, “electioneering begins to wax hot.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 203 quoting James F. Hopkins, “Election of 1824,” in History of American Presidential Elections, ed. Arthur M. Schlesinger Jr. (New York, 1985), 363.

With the creation of the Missouri Compromise came a second controversy for Missouri. Some northerners threatened “not to consent to the Missouri constitution when it came back to Congress for final approval.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 156. Henry Clay, then-Speaker of the House of Representatives, led the effort to solving this second controversy.

By 1819, the area west of the Mississippi River, known as the Missouri Territory, had obtained a population qualifying it to be admitted to the Union. Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1819-1848, 147. The only requirement to be admitted was that an enabling act be presented to Congress “authorizing Missouri voters to elect a convention to draft a state constitution.” Id. That bill was proposed, but Representative James Tallmadge proposed an amendment prohibiting further “importation of slavery” and “all children of slaves born after Missouri’s admission to the Union should become free at the age of twenty-five.” Id. This provoked great “consternation in the House of Representatives.” Id. citing Annals of Congress, 15th Cong., 2nd sess., 1170.
