Trace how disputes over federalism and sectional issues, including slavery, led to secession and the Civil War

Learning goal: Explain how disputes over the nature of federalism, complicated by economic developments in the United States, resulted in sectional issues, including slavery, which led to the American Civil War. Follow the chain from 1816 to 1861 with dated evidence at each link.

Federalism and the dispute over its nature. Federalism is the division of power between the national government and the states. The Constitution names some national powers, reserves others to the states and leaves the boundary between them to argument. Two readings competed. One held that the United States was a union of sovereign states that had created the national government and could judge when it exceeded its powers, a view usually called states' rights. The other held that the Constitution was made by the people, that national law was supreme within its sphere, and that only the federal courts, not a state, could decide the limits. The dispute over the nature of federalism was therefore a dispute about who decides.

Economic developments that complicated it. The sections developed differently. The Northeast built factories and wanted a protective tariff, a tax on imports that made foreign goods more expensive and domestic goods easier to sell. The South grew cotton for export, bought manufactured goods, and saw a tariff as a tax paid by southerners for the benefit of northern manufacturers. The West wanted cheap land and federal spending on roads and canals. Banks, currency and internal improvements divided people along the same lines. These economic developments did not create the federalism dispute, but they gave each side a concrete reason to insist on its reading of the Constitution.

Tariffs and nullification, 1828–1833. The tariff of 1828 raised rates so high that opponents called it the "Tariff of Abominations." Vice President John C. Calhoun of South Carolina wrote, anonymously, that a state could declare a federal law null within its borders. In November 1832 a South Carolina convention passed an Ordinance of Nullification declaring the tariffs of 1828 and 1832 void in the state. President Andrew Jackson answered in December 1832 that nullification was incompatible with the existence of the Union, and in March 1833 Congress passed both a Force Bill authorizing him to collect the tariff by arms and, through Henry Clay, a compromise tariff that lowered rates gradually over the following decade. South Carolina repealed its ordinance. Evidence: the state asserted a right to nullify; the national government denied it and prepared force; a compromise ended the crisis without deciding the principle.

Banking, 1832. The Second Bank of the United States, chartered in 1816, held federal deposits and regulated state banks by demanding payment in specie, gold or silver coin, for the paper notes they issued, which kept them from printing more notes than they could redeem. In McCulloch v. Maryland (1819) the Supreme Court had upheld Congress's power to charter it and denied a state's power to tax it. Jackson vetoed the bank's recharter in July 1832, arguing that the bank was unconstitutional and served the wealthy, and the charter expired in 1836. The bank war was another argument about how far national power reached, fought this time between the president and Congress rather than between a state and the nation.

Slavery in the territories, 1820–1857. Slavery became the sectional issue that the others could not be separated from, because each new territory forced a decision. The Missouri Compromise of 1820 set the 36°30′ line. The Compromise of 1850 admitted California as a free state, organized Utah and New Mexico territories with slavery to be decided by their residents, ended the slave trade in the District of Columbia and passed a stronger Fugitive Slave Act that required free-state citizens and officers to assist in returning escaped people. The Kansas–Nebraska Act of May 1854 repealed the 36°30′ limit and applied "popular sovereignty" to Kansas and Nebraska; the result was armed conflict in Kansas and the founding of the Republican Party, which opposed the extension of slavery. In Dred Scott v. Sandford (March 6, 1857) the Supreme Court ruled that Black Americans, whose ancestors had been brought as slaves, were not and could not become citizens of the United States, and that Congress had no power to bar slavery from any territory. That decision removed the compromise line as a legal option and made the federalism dispute and the slavery dispute the same argument.

From election to secession, 1860–1861. John Brown's raid on the federal arsenal at Harpers Ferry in October 1859 convinced many white southerners that the North would not restrain attacks on slavery. In November 1860 Abraham Lincoln, a Republican pledged only to stop the spread of slavery into territories, won the presidency without carrying a single southern state. South Carolina's convention voted to secede on December 20, 1860; Mississippi, Florida, Alabama, Georgia, Louisiana and Texas followed by February 2, 1861, and the seven formed the Confederate States of America in February 1861 with Jefferson Davis as president. After Confederate forces fired on Fort Sumter on April 12, 1861, and Lincoln called for troops to put down the rebellion, Virginia, Arkansas, North Carolina and Tennessee also seceded, making eleven. Four slave states, Delaware, Maryland, Kentucky and Missouri, remained in the Union.

A worked model of the chain. Start with a fact: the 1828 tariff raised import duties. Add the economic development: South Carolina's planters sold cotton abroad and bought imports, so the tariff cost them. Add the federalism claim: the state asserted the power to nullify. Add the national response: Jackson's proclamation and the Force Bill. Now ask what was left undecided. The compromise tariff lowered the rates but never settled whether a state could nullify. The unsettled principle reappeared in 1860 in a stronger form, secession, attached to a more explosive issue, slavery. That is what the standard means by disputes over federalism, complicated by economic developments, resulting in sectional issues that led to war.

Misconceptions. First, "the war was about tariffs" and "the war was about states' rights" are both incomplete: the secession declarations of 1860 and 1861 named the protection of slavery as the reason, and the states' rights being claimed were rights concerning slavery. Second, "the North opposed slavery, the South supported it" is too simple: most northern voters in 1860 opposed slavery's extension, not its existence where it stood, and the border slave states stayed in the Union. State positions precisely and cite the document that shows them.

Worked nullification analysis: Question: did the Nullification Crisis decide whether a state can void a federal law? Evidence: the 1832 ordinance claimed it; the 1832 proclamation denied it; the 1833 Force Bill authorized collection by arms; the 1833 compromise tariff lowered rates; South Carolina repealed the ordinance. Conclusion: the crisis ended by compromise on the tariff, not by a ruling on the principle, so the principle stayed available for 1860. The step students skip is checking what each document decided rather than assuming the last event settled everything.

Worked comparison of three compromises: 1820: Missouri slave, Maine free, no slavery north of 36°30′ in the rest of the Louisiana Purchase (Missouri itself lies north of the line). 1850: California free, popular sovereignty in Utah and New Mexico, stronger Fugitive Slave Act. 1854: popular sovereignty in Kansas and Nebraska, the 36°30′ line repealed. Reading across, the rule moved from a fixed geographic line to a vote by settlers, which shifted the contest from Congress to the territories themselves and produced violence in Kansas. In 1857 the Court then said Congress could not draw any line, which left no compromise to make.

Worked reading of Dred Scott: Two holdings: Black Americans, free or enslaved, were not, and could not become, citizens of the United States and so could not sue in federal court; and Congress could not prohibit slavery in the territories, so the Missouri Compromise had been unconstitutional. The Court also held that Scott's years in free Illinois and free territory did not make him free once he returned to Missouri, whose law governed his status. Consequence for federalism: the national government was told it lacked a power it had used since 1789, when the first Congress re-enacted the Northwest Ordinance, and again in the Missouri Compromise of 1820. The decision did not say that free states had lost the power to bar slavery within their own borders, but Republicans warned that such a ruling could come next, and they responded that they would seek to change the Court's view, which is why the 1860 election became a test of the decision.

Supported chain diagram: Copy the flow diagram and, beside each step, write one piece of dated evidence (a law, ruling, ordinance, proclamation or vote) and one sentence saying what that step left undecided. The final step should name the eleven seceding states in the order of the two waves, before and after Fort Sumter, and the four slave states that stayed.

Independent performance: Write an explanation of how disputes over the nature of federalism, complicated by economic developments, resulted in sectional issues, including slavery, that led to the Civil War. Success criteria: the two readings of federalism are stated in your own words; at least three dated links (a tariff or bank episode, a territorial compromise, a court ruling or election) are in the correct order; the explanation says what each compromise failed to settle; slavery is identified as the issue the secession declarations themselves named; and any sentence assigning blame or motive is labeled as interpretation.
