The attentive reader of the preceding chapters—especially if he has compared their statements with contemporaneous records and other original sources of information—will already have found evidence enough to enable him to discern the falsehood of these representations, and to perceive that, to whatever extent the question of slavery may have served as an occasion, it was far from being the cause of the conflict.

I have not attempted, and shall not permit myself to be drawn into any discussion of the merits or demerits of slavery as an ethical or even as a political question. It would be foreign to my purpose, irrelevant to my subject, and would only serve—as it has invariably served, in the hands of its agitators—to "darken counsel" and divert attention from the genuine issues involved.

As a mere historical fact, we have seen that African servitude among us—confessedly the mildest and most humane of all institutions to which the name "slavery" has ever been applied—existed in all the original States, and that it was recognized and protected in the fourth article of the Constitution. Subsequently, for climatic, industrial, and economical—not moral or sentimental—reasons, it was abolished in the Northern, while it continued to exist in the Southern States. Men differed in their views as to the abstract question of its right or wrong, but for two generations after the Revolution there was no geographical line of demarkation for such differences. The African slave-trade was carried on almost exclusively by New England merchants and Northern ships. Mr. Jefferson—a Southern man, the founder of the Democratic party, and the vindicator of State rights—was in theory a consistent enemy to every form of slavery. The Southern States took the lead in prohibiting the slave-trade, and, as we have seen, one of them (Georgia) was the first State to incorporate such a prohibition in her organic Constitution. Eleven years after the agitation on the Missouri question, when the subject first took a sectional shape, the abolition of slavery was proposed and earnestly debated in the Virginia Legislature, and its advocates were so near the accomplishment of their purpose, that a declaration in its favor was defeated only by a small majority, and that on the ground of expediency. At a still later period, abolitionist lecturers and teachers were mobbed, assaulted, and threatened with tar and feathers in New York, Pennsylvania, Massachusetts, New Hampshire, Connecticut, and other States. One of them (Lovejoy) was actually killed by a mob in Illinois as late as 1837.

These facts prove incontestably that the sectional hostility which exhibited itself in 1820, on the application of Missouri for admission into the Union, which again broke out on the proposition for the annexation of Texas in 1844, and which reappeared after the Mexican war, never again to be suppressed until its fell results had been fully accomplished, was not the consequence of any difference on the abstract question of slavery. It was the offspring of sectional rivalry and political ambition. It would have manifested itself just as certainly if slavery had existed in all the States, or if there had not been a negro in America. No such pretension was made in 1803 or 1811, when the Louisiana purchase, and afterward the admission into the Union of the State of that name, elicited threats of disunion from the representatives of New England. The complaint was not of slavery, but of "the acquisition of more weight at the other extremity" of the Union. It was not slavery that threatened a rupture in 1832, but the unjust and unequal operation of a protective tariff.

It happened, however, on all these occasions, that the line of demarkation of sectional interests coincided exactly or very nearly with that dividing the States in which negro servitude existed from those in which it had been abolished. It corresponded with the prediction of Mr. Pickering, in 1803, that, in the separation certainly to come, "the white and black population would mark the boundary"—a prediction made without any reference to slavery as a source of dissension.

Of course, the diversity of institutions contributed, in some minor degree, to the conflict of interests. There is an action and reaction of cause and consequence, which limits and modifies any general statement of a political truth. I am stating general principles—not defining modifications and exceptions with the precision of a mathematical proposition or a bill in chancery. The truth remains intact and incontrovertible, that the existence of African servitude was in no wise the cause of the conflict, but only an incident. In the later controversies that arose, however, its effect in operating as a lever upon the passions, prejudices, or sympathies of mankind, was so potent that it has been spread, like a thick cloud, over the whole horizon of historic truth.

As for the institution of negro servitude, it was a matter entirely subject to the control of the States. No power was ever given to the General Government to interfere with it, but an obligation was imposed to protect it. Its existence and validity were distinctly recognized by the Constitution in at least three places:

First, in that part of the second section of the first article which prescribes that "representatives and direct taxes shall be apportioned among the several States which may be included within this Union, according to their respective members, which shall be determined by adding to the whole number of free persons, including those bound to service for a term of years, and, excluding Indians not taxed, three fifths of all other persons." "Other persons" than "free persons" and those "bound to service for a term of years" must, of course, have meant those permanently bound to service.

Secondly, it was recognized by the ninth section of the same article, which provided that "the migration or importation of such persons as any of the States now existing shall think proper to admit shall not be prohibited by Congress prior to the year one thousand eight hundred and eight." This was a provision inserted for the protection of the interests of the slave-trading New England States, forbidding any prohibition of the trade by Congress for twenty years, and thus virtually giving sanction to the legitimacy of the demand which that trade was prosecuted to supply, and which was its only object.

Again, and in the third place, it was specially recognized, and an obligation imposed upon every State, not only to refrain from interfering with it in any other State, but in certain cases to aid in its enforcement, by that clause, or paragraph, of the second section of the fourth article which provides as follows:
