Causes of the Civil War

The Civil War was caused by a myriad of conflicting pressures, principles, and prejudices, fueled by sectional differences and pride, and set into motion by a most unlikely set of political events.

At the root of all of the problems was the institution of slavery, which had been introduced into North America in early colonial times. The American Revolution had been fought to validate the idea that all men were created equal, yet slavery was legal in all of the thirteen colonies throughout the revolutionary period. Although it was largely gone from the northern states by 1787, it was still enshrined in the new Constitution of the United States, not only at the behest of the Southern ones, but also with the approval of many of the Northern delegates who saw that there was still much money to be made in the slave trade by the Yankee shipping industry. Eventually its existence came to color every aspect of American life.

At the Constitutional Convention there were arguments over slavery. Representatives of the Northern states claimed that if the Southern slaves were mere property, then they should not be counted toward voting representation in Congress. Southerners, placed in the difficult position of trying to argue, at least in this case, that the slaves were human beings, eventually came to accept the three-fifths compromise, by which five slaves counted as three free men toward that representation. By the end of the convention the institution of slavery itself, though never specifically mentioned, was well protected within the body of the Constitution.

It seemed to Thomas Jefferson and many others that slavery was on its way out, doomed to die a natural death. It was becoming increasingly expensive to keep slaves in the agrarian society of the south. Northern and Southern members of Congress voted together to abolish the importation of slaves from overseas in 1808, but the domestic slave trade continued to flourish. The invention of the cotton gin made the cultivation of cotton on large plantations using slave labor a profitable enterprise in the deep South. The slave became an ever more important element of the southern economy, and so the debate about slavery, for the southerner, gradually evolved into an economically based question of money and power, and ceased to be a theoretical or ideological issue at all. It became an institution that southerners felt bound to protect.

But even as the need to protect it grew, the ability, or at least the perceived ability of the South to do so was waning. Southern leaders grew progressively more sensitive to this condition. In 1800 half of the population of the United States had lived in the South. But by 1850 only a third lived there and the disparity continued to widen. While northern industrial opportunity attracted scores of immigrants from Europe in search of freedom the South's population stagnated. Even as slave states were added to the Union to balance the number of free ones, the South found that its representatives in the House had been overwhelmed by the North’s explosive growth. More and more emphasis was now placed on maintaining parity in the Senate. Failing this, the paranoid theory went, the South would find itself at the mercy of a government in which it no longer had an effective voice. Never mind that slavery was protected under the constitution, and that it would have been impossible to make amendments to abolish it. Jefferson Davis, at the time a Senator from Mississippi, summed up the sectionalist argument himself. Speaking, in effect, to the people of the North concerning slavery, “It is not humanity that influences you… it is that you may have a majority in the Congress of the United States and convert the Government into an engine of Northern aggrandizement… you want by an unjust system of legislation to promote the industry of the United States at the expense of the people of the South.” There, in plain English, is the shrill, accusatory language of sectionalism.

Nothing but bitterness and bad feeling could come of it. From such a position it was a short step to the proposition that if a state or section of the country no longer felt itself represented in, or fairly treated by, the Federal Government, then it had the right to dissolve its association with that government. It could secede from the Union. The use of force to stop a state from seceding was, the argument went, unconstitutional, since the Union itself was a creature of the states. It had been wholly created by them. Moreover no provision had been made for such an eventuality in the Constitution.

The Unionist response was that the Preamble of the Constitution stated that the Union derived its power from the people as a whole, and that they alone could dissolve it. President Andrew Jackson, himself a Southerner, had threatened in 1832 to send troops to force South
