Thus far, most of the political victories had been with the slave-power, and the South became correspondently arrogant and defiant. The war of ideas against Southern interests now raged with ominous and increasing force in all the Northern States. Public opinion became more and more inflamed. Passions became excited in cities and towns and villages which had been dormant since the Constitution had been adopted. The decree of the North went forth that there should be no more accession of slave territory; and, more than this, the population spread with unexampled rapidity toward the Pacific Ocean in consequence of the discovery of gold in California, in 1848, and attracted by the fertile soil of Oregon. Immigrants from all nations came to seek their fortunes in territories north of 36°30'.
What Calhoun had anticipated in 1836, when he cast his eyes on Texas, did not take place. Slave territory indeed was increased, but free territory increased still more rapidly. The North was becoming richer and richer, and the South scarcely held its own. The balance which he thought would be in favor of the South, he now saw inclining to the North. Northern States became more numerous than Southern ones, and more populous, more wealthy, and more intelligent. The political power of the Union, when Mr. Polk closed his inglorious administration, was perceptibly with the North, and not political power only, but moral power. The great West was the soil of freemen.
But the haughty and defiant spirit of Calhoun was not broken. He prophesied woes. He became sad and dejected, but more and more uncompromising, more and more dictatorial. He would not yield. "If we yield an inch," said he, "we are lost." The slightest concession, in his eyes, would be fatal. When he declared his nullification doctrines it was because he thought that State rights were invaded by hostile tariffs. But after the Mexican War slavery was to him a matter of life and death. He made many excellent and powerful speeches, which tasked the intellect of Webster to refute; but, whatever the subject, it was seen only through his Southern spectacles, and argued from partisan grounds and with partisan zeal. Everything he uttered was with a view of consolidating the South, and preparing it for disunion and secession, as the only way to preserve the beloved institution. In his eyes, slavery and the Union could not co-exist. This he saw plainly, but if either must perish it should be the Union; and this doctrine he so constantly reiterated that he won over to it nearly the entire South. But in consolidating the South, he also consolidated the North. He forced on the issue, believing that even yet the South, united with Northern allies, was the stronger, and that it could establish its independence on a slavery basis. The Union was no union at all, and its Constitution was a worthless parchment. "He proposed a convention of the Southern States which should agree that, until full justice was rendered to the South, all the Southern ports should be closed to the sea-going vessels of the North." He arrogantly would deprive the North even of its constitutional rights in reference to the exclusion of slavery from the Territories. In no way should the North meddle with the slavery question, on penalty of secession; and the sooner this was understood the better. "We are," said he, "relatively stronger than we shall be hereafter, politically and morally."
The great fight arose in 1849. The people in the Northwestern territories had been encouraged to form governments, and had already tasted the delights of self-rule. President Polk had recommended the extension of the old Missouri Compromise line of 36° 30' westward to the Pacific, leaving the territory south of that open to slavery. This would divide California, and was opposed by all parties. Calhoun now went so far as to claim the constitutional right to take slaves into any Territory, while Webster argued the power of Congress to rule the Territories until they should become States. So excited was the discussion that a convention of Southern States was held to frame a separate government for the "United States South." The threat of secession was ever their most potent argument. The contest in Congress centred upon the admission of California as a State and the condition of slavery in the Territories of Utah and New Mexico.
A great crisis had now arrived. Clay, "the great pacificator," once more stepped into the arena with a new compromise. To provide for concessions on either side, he proposed the admission of California (whose new constitution prohibited slavery); the organization of Utah and New Mexico as Territories without mention of slavery (leaving it to the people); the arrangement of the boundary of Texas; the abolition of slavery in the District of Columbia; and the enactment of a more stringent fugitive-slave law, commanding the assistance of people in the free States to capture runaways, when summoned by the authorities.
The general excitement over the discussion of this bill will never be forgotten by those who witnessed it. The South raged, and the North blazed with indignation,--especially over the Fugitive-Slave Bill.
Meanwhile Calhoun was dying. His figure was bent, his voice was feeble, his face was haggard, but his superb intellect still retained its vigor to the last. Among the multitude of ringing appeals to the reason and moral sense of the North was a newspaper article from The Independent of New York, by a young Congregational minister, Henry Ward Beecher. It was entitled "Shall we Compromise?" and made clear and plain the issue before the people: "Slavery is right; Slavery is wrong: Slavery shall live; Slavery shall die: are these conflicts to be settled by any mode of parcelling out certain Territories?" This article was read to Calhoun upon his dying bed. "Who wrote that?" he asked. The name was given him. "That man understands the thing. He has gone to the bottom of it. He will be heard from again." It was what the great Southerner had foreseen and foretold from the first.
The compromise bill at last became a law. It averted the final outbreak for ten years longer, but contained elements that were to be potent factors in insuring the final crisis.
With the burden of the whole South upon his shoulders Calhoun tottered to the grave a most unhappy man, for though he saw the "irrepressible conflict" as clearly as Seward had done, he also saw that the South, even if successful, as he hoped, must go through a sea of tribulation. When he was no longer able to address the Senate in person he still waged the battle. His last great speech was read to the Senate by Mr. Mason of Virginia, on the 4th of March, 1850. It was not bitter, nor acrimonious; it was a doleful lament that the Southern States could not long remain in the Union with any dignity, now that the equilibrium was destroyed. He felt that he had failed, but also that he had done his duty; and this was his only consolation in view of approaching disasters. On the last day of March he died, leaving behind him his principles, so full of danger and sophistries, but at the same time an unsullied name, and the memory of earlier public services and of private virtues which had secured to him the respect of all who knew him.
In reviewing the career of Mr. Calhoun it would seem that the great error and mistake of his life was his disloyalty to the Union. When he advocated State rights as paramount over those of the general government he merely took the ground which was discussed over and over again at the formation of the Constitution, and which resulted in a compromise that, with control over matters of interest common to all States, the central government should have no power over the institution of slavery, which was a domestic affair in the Southern States. Only these States, it was settled, had supreme control over their own "peculiar institution." As a politician, representing Southern interests, he cannot be severely condemned for his fear and anger over the discussion of the slavery question, which, politically considered, was out of the range of Congressional legislation or popular agitation. But when he advocated or threatened the secession of the Southern States from the Union, unless the slavery question was let alone entirely both by Congress and the Northern States, he was unpatriotic, false in his allegiance, and unconstitutional in his utterances. A State has a right to enter the Union or not, remaining of course, in either case, United States territory, over which Congress has legislative power. But when once it has entered into the Union, it must remain there as a part of the whole. Otherwise the States would be a mere league, as in the Revolutionary times.
