The South claimed the sovereignty of States, but claimed the right to coerce into their confederation such States as they wanted, that is, all the States where slavery existed. They did not seem to think this course inconsistent. The fact is, the Southern slave-owners believed that, in some way, the ownership of slaves conferred a sort of patent of nobility-a right to govern independent of the interest or wishes of those who did not hold such property. They convinced themselves, first, of the divine origin of the institution and, next, that that particular institution was not safe in the hands of any body of legislators but themselves.
