“Is it true that the North hates slavery? My next proposition is that in the past the North has invariably exerted against slavery, all the power which it had at the time. The question merely was what was the amount of power it had to exert against it. They abolished slavery in that magnificent empire which you presented to the North; they abolished slavery in every Northern State, one after another; they abolished slavery in all the territory above the line of 36 30, which comprised about one million square miles. They have endeavored to put the Wilmot Proviso upon all the other territories of the Union, and they succeeded in putting it upon the territories of Oregon and Washington. They have taken from slavery all the conquests of the Mexican war, and appropriated it all to anti-slavery purposes; and if one of our fugitives escapes into the territories, they do all they can to make a free man of him; they maltreat his pursuers, and sometimes murder them. They make raids into your territory with a view to raise insurrection, with a view to destroy and murder indiscriminately all classes, ages and sexes, and when the base perpetrators are caught and brought to punishment, condign punishment, half the north go into mourning. If some of the perpetrators escape, they are shielded by the authorities of these Northern States-not by an irresponsible mob, but, by the regularly organized authorities of the States.”

But in 1793 the cotton gin was invented, shortly after the power loom in England. This was the onset of the industrial revolution. Almost overnight, a new industry or rather a series of new industries, proliferating worldwide, was born. It began with the growing of cotton but was followed by its manufacture into a wide variety of products, especially cotton cloth and cotton clothing. Suddenly, slave labor became vastly more profitable. In the decade before the Civil War, the value of slaves doubled. Once again, greed overwhelmed all other motives. From being regarded as a temporary evil, as it was at the founding, slavery came to be regarded as a positive—and permanent—good.

Context: In the first place, I say that the North hates slavery, and, in using that expression I speak wittingly. In saying that the Black Republican party of the North hates slavery, I speak intentionally. If there is a doubt upon that question in the mind of any one who listens to me, a few of the multitude of proofs which could fill this room, would, I think, be sufficient to satisfy him. I beg to refer to a few of the proofs that are so abundant; and the first that I shall adduce consists in two extracts from a speech of Lincoln's, made in October 1858. They are as follows: 'I have always hated slavery as much as any abolitionist; I have always been an old line Whig; I have always hated it and I always believed it in the course of ultimate extinction, and if I were in Congress and a vote should come up on the question, whether slavery should be excluded from the territory, in spite of the Dred Scott decision, I would vote that it should.

The honour of the States, as well as justice and humanity, in my opinion, loudly call upon them to emancipate these unhappy people. To contend for our own liberty, and to deny that blessing to others, involves an inconsistency not to be excused.

Context: But one may ask, how is it that slavery, or any other form of invidious discrimination, has played so great a role in American history? How could a nation, dedicated at its birth to the proposition that all men are created equal, have tolerated slavery and its effects so long? If we look to the long history of mankind, however, we will ask a different question. Slavery was lawful in every one of the original thirteen states. There was accordingly nothing remarkable in the fact that slavery was not abolished immediately on independence. What is remarkable is that a slave-owning nation would declare that all men are created equal, and thereby make the abolition of slavery a moral and political necessity. To accomplish that task would not be easy. We need to see the dimensions of that task to appreciate its difficulty.

Speech to the Virginia Convention (1861)
Context: If things are allowed to go on as they are, it is certain that slavery is to be abolished except in Georgia and the other cotton States, and I doubt, ultimately in these States also. By the time the North shall have attained the power, the black race will be in a large majority, and then we will have black governors, black legislatures, black juries, black everything. Is it to be supposed that the white race will stand for that? It is not a supposable case. War will break out everywhere like hidden fire from the earth. We will be overpowered and our men will be compelled to wander like vagabonds all over the earth, and as for our women, the horrors of their state we cannot contemplate in imagination. We will be completely exterminated, and the land will be left in the possession of the blacks, and then it will go back to a wilderness and become another Africa or Saint Domingo. Join the north and what will become of you? They will hate you and your institutions as much as they do now, and treat you accordingly. Suppose they elevated Charles Sumner to the presidency? Suppose they elevated Fred Douglass, your escaped slave, to the presidency? What would be your position in such an event? I say give me pestilence and famine sooner than that.
