Thus, with the author of the Declaration of Independence, the policy of prohibiting slavery in new territory originated. Thus, away back to the Constitution, in the pure, fresh, free breath of the Revolution, the State of Virginia and the national Congress put that policy into practice. Thus, through more than sixty of the best years of the republic, did that policy steadily work to its great and beneficent end. And thus, in those five States, and in five millions of free, enterprising people, we have before us the rich fruits of this policy.
But now new light breaks upon us. Now Congress declares this ought never to have been, and the like of it must never be again. The sacred right of self-government is grossly violated by it. We even find some men who drew their first breath—and every other breath of their lives—under this very restriction, now live in dread of absolute suffocation if they should be restricted in the "sacred right" of taking slaves to Nebraska. That perfect liberty they sigh for—the liberty of making slaves of other people, Jefferson never thought of, their own fathers never thought of, they never thought of themselves, a year ago. How fortunate for them they did not sooner become sensible of their great misery! Oh, how difficult it is to treat with respect such assaults upon all we have ever really held sacred!
But to return to history. In 1803 we purchased what was then called Louisiana, of France. It included the present States of Louisiana, Arkansas, Missouri, and Iowa; also the Territory of Minnesota, and the present bone of contention, Kansas and Nebraska. Slavery already existed among the French at New Orleans, and to some extent at St. Louis. In 1812 Louisiana came into the Union as a slave State, without controversy. In 1818 or '19, Missouri showed signs of a wish to come in with slavery. This was resisted by Northern members of Congress; and thus began the first great slavery agitation in the nation. This controversy lasted several months, and became very angry and exciting—the House of Representatives voting steadily for the prohibition of slavery in Missouri, and the Senate voting as steadily against it. Threats of the breaking up of the Union were freely made, and the ablest public men of the day became seriously alarmed. At length a compromise was made, in which, as in all compromises, both sides yielded something. It was a law, passed on the 6th of March, 1820, providing that Missouri might come into the Union with slavery, but that in all the remaining part of the territory purchased of France which lies north of thirty-six degrees and thirty minutes north latitude, slavery should never be permitted. This provision of law is the "Missouri Compromise." In excluding slavery north of the line, the same language is employed as in the Ordinance of 1787. It directly applied to Iowa, Minnesota, and to the present bone of contention, Kansas and Nebraska. Whether there should or should not be slavery south of that line, nothing was said in the law. But Arkansas constituted the principal remaining part south of the line; and it has since been admitted as a slave State, without serious controversy. More recently, Iowa, north of the line, came in as a free State without controversy. Still later, Minnesota, north of the line, had a territorial organization without controversy. Texas, principally south of the line, and west of Arkansas, though originally within the purchase from France, had, in 1819, been traded off to Spain in our treaty for the acquisition of Florida. It had thus become a part of Mexico. Mexico revolutionized and became independent of Spain. American citizens began settling rapidly with their slaves in the southern part of Texas. Soon they revolutionized against Mexico, and established an independent government of their own, adopting a constitution with slavery, strongly resembling the constitutions of our slave States. By still another rapid move, Texas, claiming a boundary much farther west than when we parted with her in 1819, was brought back to the United States, and admitted into the Union as a slave State. Then there was little or no settlement in the northern part of Texas, a considerable portion of which lay north of the Missouri line; and in the resolutions admitting her into the Union, the Missouri restriction was expressly extended westward across her territory. This was in 1845, only nine years ago.
Thus originated the Missouri Compromise; and thus has it been respected down to 1845. And even four years later, in 1849, our distinguished Senator, in a public address, held the following language in relation to it:
"The Missouri Compromise has been in practical operation for about a quarter of a century, and has received the sanction and approbation of men of all parties in every section of the Union. It has allayed all sectional jealousies and irritations growing out of this vexed question, and harmonized and tranquillized the whole country. It has given to Henry Clay, as its prominent champion, the proud sobriquet of the 'Great Pacificator,' and by that title, and for that service, his political friends had repeatedly appealed to the people to rally under his standard as a Presidential candidate, as the man who had exhibited the patriotism and power to suppress an unholy and treasonable agitation, and preserve the Union. He was not aware that any man or any party, from any section of the Union, had ever urged as an objection to Mr. Clay that he was the great champion of the Missouri Compromise. On the contrary, the effort was made by the opponents of Mr. Clay to prove that he was not entitled to the exclusive merit of that great patriotic measure, and that the honor was equally due to others, as well as to him, for securing its adoption; that it had its origin in the hearts of all patriotic men, who desired to preserve and perpetuate the blessings of our glorious Union—an origin akin to that of the Constitution of the United States, conceived in the same spirit of fraternal affection, and calculated to remove forever the only danger which seemed to threaten, at some distant day, to sever the social bond of union. All the evidences of public opinion at that day seemed to indicate that this compromise had been canonized in the hearts of the American people, as a sacred thing which no ruthless hand would ever be reckless enough to disturb."
I do not read this extract to involve Judge Douglas in an inconsistency. If he afterward thought he had been wrong, it was right for him to change. I bring this forward merely to show the high estimate placed on the Missouri Compromise by all parties up to so late as the year 1849.
But going back a little in point of time. Our war with Mexico broke out in 1846. When Congress was about adjourning that session, President Polk asked them to place two millions of dollars under his control, to be used by him in the recess, if found practicable and expedient, in negotiating a treaty of peace with Mexico, and acquiring some part of her territory. A bill was duly gotten up for the purpose, and was progressing swimmingly in the House of Representatives, when a member by the name of David Wilmot, a Democrat from Pennsylvania, moved as an amendment, "Provided, that in any territory thus acquired there never shall be slavery."
This is the origin of the far-famed Wilmot Proviso. It created a great flutter; but it stuck like wax, was voted into the bill, and the bill passed with it through the House. The Senate, however, adjourned without final action on it, and so both appropriation and proviso were lost for the time. The war continued, and at the next session the President renewed his request for the appropriation, enlarging the amount, I think, to three millions. Again came the proviso, and defeated the measure. Congress adjourned again, and the war went on. In December, 1847, the new Congress assembled. I was in the lower House that term. The Wilmot Proviso, or the principle of it, was constantly coming up in some shape or other, and I think I may venture to say I voted for it at least forty times during the short time I was there. The Senate, however, held it in check, and it never became a law. In the spring of 1848 a treaty of peace was made with Mexico, by which we obtained that portion of her country which now constitutes the Territories of New Mexico and Utah and the present State of California. By this treaty the Wilmot Proviso was defeated, in so far as it was intended to be a condition of the acquisition of territory. Its friends, however, were still determined to find some way to restrain slavery from getting into the new country. This new acquisition lay directly west of our old purchase from France, and extended west to the Pacific Ocean, and was so situated that if the Missouri line should be extended straight west, the new country would be divided by such extended line, leaving some north and some south of it. On Judge Douglas's motion, a bill, or provision of a bill, passed the Senate to so extend the Missouri line. The proviso men in the House, including myself, voted it down, because, by implication, it gave up the southern part to slavery, while we were bent on having it all free.
In the fall of 1848 the gold-mines were discovered in California. This attracted people to it with unprecedented rapidity, so that on, or soon after, the meeting of the new Congress in December, 1849, she already had a population of nearly a hundred thousand, had called a convention, formed a State constitution excluding slavery, and was knocking for admission into the Union. The proviso men, of course, were for letting her in, but the Senate, always true to the other side, would not consent to her admission, and there California stood, kept out of the Union because she would not let slavery into her borders. Under all the circumstances, perhaps, this was not wrong. There were other points of dispute connected with the general question of Slavery, which equally needed adjustment. The South clamored for a more efficient fugitive slave law. The North clamored for the abolition of a peculiar species of slave trade in the District of Columbia, in connection with which, in view from the windows of the Capitol, a sort of negro livery-stable, where droves of negroes were collected, temporarily kept, and finally taken to Southern markets, precisely like droves of horses, had been openly maintained for fifty years. Utah and New Mexico needed territorial governments; and whether slavery should or should not be prohibited within them was another question. The indefinite western boundary of Texas was to be settled. She was a slave State, and consequently the farther west the slavery men could push her boundary, the more slave country they secured; and the farther east the slavery opponents could thrust the boundary back, the less slave ground was secured. Thus this was just as clearly a slavery question as any of the others.
These points all needed adjustment, and they were held up, perhaps wisely, to make them help adjust one another. The Union now, as in 1820, was thought to be in danger, and devotion to the Union rightfully inclined men to yield somewhat in points where nothing else could have so inclined them. A compromise was finally effected. The South got their new fugitive slave law, and the North got California, (by far the best part of our acquisition from Mexico) as a free State. The South got a provision that New Mexico and Utah, when admitted as States, may come in with or without slavery as they may then choose; and the North got the slave trade abolished in the District of Columbia.. The North got the western boundary of Texas thrown farther back eastward than the South desired; but, in turn, they gave Texas ten millions of dollars with which to pay her old debts. This is the Compromise of 1850.
