On this day in 1860, South Carolina seceded from the Union. Thus began a series of secessions that soon led to the American Civil War—secessions that, according to more modern Confederate apologists, had nothing whatsoever to do with slavery. To give those apologists some ammunition, let us quote from the Declaration of the Immediate Causes by which South Carolina justified her secession.

We affirm that these ends for which this Government was instituted have been defeated, and the Government itself has been made destructive of them by the action of the non-slaveholding States. Those States have assumed the right of deciding upon the propriety of our domestic institutions; and have denied the rights of property established in fifteen of the States and recognized by the Constitution; they have denounced as sinful the institution of Slavery; they have permitted the open establishment among them of societies, whose avowed object is to disturb the peace and to eloign the property of the citizens of other States. They have encouraged and assisted thousands of our slaves to leave their homes; and those who remain, have been incited by emissaries, books and pictures to servile insurrection.

For twenty-five years this agitation has been steadily increasing, until it has now secured to its aid the power of the Common Government. Observing the forms of the Constitution, a sectional party has found within that article establishing the Executive Department, the means of subverting the Constitution itself. A geographical line has been drawn across the Union, and all the States north of that line have united in the election of a man to the high office of President of the United States whose opinions and purposes are hostile to slavery. He is to be entrusted with the administration of the Common Government, because he has declared that that "Government cannot endure permanently half slave, half free," and that the public mind must rest in the belief that Slavery is in the course of ultimate extinction.

​This sectional combination for the subversion of the Constitution, has been aided in some of the States by elevating to citizenship, persons, who, by the Supreme Law of the land, are incapable of becoming citizens; and their votes have been used to inaugurate a new policy, hostile to the South, and destructive of its peace and safety.

On the 4th March next, this party will take possession of the Government. It has announced, that the South shall be excluded from the common Territory; that the Judicial Tribunals shall be made sectional, and that a war must be waged against slavery until it shall cease throughout the United States.

The Guaranties of the Constitution will then no longer exist; the equal rights of the States will be lost. The slaveholding States will no longer have the power of self-government, or self-protection, and the Federal Government will have become their enemy.

Sectional interest and animosity will deepen the irritation, and all hope of remedy is rendered vain, by the fact that public opinion at the North has invested a great political error with the sanctions of a more erroneous religious belief.

Well, it may be true, then, that the secession had something to do with slavery. In fact, if there are any remaining Confederate apologists who still insist that the secession had nothing to do with slavery, let them peruse the whole document at their leisure. Dr. Boli assigns them this task: let them find a single reason for secession expressed in that document that is not related to slavery. Dr. Boli will wait right here.
