<p>“Slavery was certainly a factor and I did a poor job of defining my point”</p>
<p>Slavery was not just “a factor”, at least not one that was equal to all others. It was the figurative match that lit the fire that was the Civil War. The other issues did not lead to war as slavery did. Indeed, each time they arose, the sections developed compromises that averted continual conflict. But those early debates over tariffs did influence the war in that they helped create the sectionalist hostility between the northern and southern states. Your article is correct that the primary issue of debate prior to 1850 (the article is wrong when it claims 1860), concerned tariffs. But we should note that your nps article was written for children, and so it is understandably incomplete since children will not generally understand the link between tax law and the moral implications of humans as property.</p>
<p>In truth, the division between the issues of tariffs and slavery was not as clean as you may wish to believe. In fact, the South openly advanced the argument that states had a right to nullify federal tariff laws with which they disagreed, and since states had a right to nullify tariff law, they had a right to nullify slave laws. John Calhoun, who actually developed the Nullification doctrine that fueled one of the chief uprisings on tariffs, was very clear on this point. [His</a> “opposition to tariffs, or more accurately the federal powers they implied, cannot be separated from his pressing desire to preserve the slave system.]( <a href=“About Tax Notes”>About Tax Notes) He feared that as border-south states gravitated to northern economic orbits, slavery in those states would grow less economically viable, their percentage of black slaves would diminish, and anti-slavery factions would succeed in eliminating slavery there (the percentage of slaves in states like Maryland had dropped precipitously since 1790). If slavery evaporated at the periphery, Calhoun believed, southern slave interests would face perpetual political perils. The same geographic coalitions that enacted the tariff laws in Congress could succeed in limiting slavery’s expansion into western territories, and might even threaten the institution in the deep south. Kentucky’s Henry Clay, one of the congressional champions of the tariff, actually proposed that some of the revenue collected be used to fund state colonization societies dedicated to relocating African Americans overseas. By diffusing the American black population abroad, such organizations effectively sought to phase out slavery in the United States. In this context, Calhoun and his supporters targeted the tariff issue to test the limits of federal power, since the south had continually lost tariff-related battles.”</p>
<p>Eventually slavery took a more prominent place in the tariff debate so that by 1850 tariffs were rarely discussed at all. Southern whites simply continued moving North to get the jobs created by the rapidly industrializing North, and this made the North even more powerful, politically speaking. Slavery became the one issue provoking such hostility between the states that, unlike tariffs, no compromise was possible. As one then future Confederate general remarked, “it is apparent, horribly apparent, that the slavery question rides insolently over every other everywhere – in fact that is the only question which in the least affects the results of the elections….I think then, 1st, that the only safety of the South from abolition universal is to be found in an early dissolution of the Union." [SEE Allan Nevins’, The Fruits of Manifest Destiny pages 240-241.]</p>
<p>It would be wrong to claim that the North wanted to end slavery purely because of slavery’s immorality. That is partially true, since Northern abolitionists continually made this argument. But there were many factors involved. Very many Northerners did not like the agitation caused by abolitionists because many Northerners were from the South, having moved there to get jobs in the new factories. These Northern southerners were sympathetic to the South. Other Northerners identified with the moral issue, but not enough to cause war over it. Still others were like Lincoln. They desired to end slavery, but not where it existed. They hoped for a gradual destruction of slavery by attrition. Generally, the moral conscience over slavery did not come from the South. It came out of the North, and it was due in large part because of Northerners like the Quakers, and then later like those comprising the abolitionists.</p>
<p>When in 1860 Abe Lincoln decided to run for the presidency, South Carolina declared it would break the Union if he won office because Lincoln had been adamant that he would not permit slavery’s westward expansion. By this time Southern leader after southern leader declared, in writing and in speeches, that slavery, not tariffs, was the issue for which they would fight and die. James H. Hammond, for example, a Congressman from South Carolina declared openly, along with vast numbers of Southern leaders “Sir, I do firmly believe that domestic slavery, regulated as ours is, produces the highest toned, the purest, best organization of society that has ever existed on the face of the earth….the moment this House undertakes to legislate upon this subject, it dissolves the Union. Should it be my fortune to have a seat upon this floor, I will abandon it the instant the first decisive step is taken looking towards legislation of this subject. I will go home to preach, and if I can, practice, disunion, and civil war, if needs be. A revolution must ensue, and this republic sink in blood.” (SEE William Miller, “Arguing About Slavery”).</p>
<p>When Lincoln won the presidency, the entire South followed South Carolina into secession and Civil War – and slavery was the chief and immediate cause of it.</p>
