Long ere this, all the Northern and Middle States had made provision for the emancipation of such slaves as remained within their borders, and only a few years previous (in 1829 and 1831-32) Virginia had made strong but insufficient efforts toward the same end. The failure to free Virginia of Slavery—the effort to accomplish which had been made by some of the greatest of her statesmen—only served to rivet the chains of human bondage more securely throughout all the Slave States, and from that time on, no serious agitation occurred in any one of them, looking toward even the most gradual emancipation. On the other hand, the advocates of the extension of the Slave-Power by the expansion of Slave-territory, were ever on the alert, they considered it of the last importance to maintain the balance of power between the Slave States and the Free States. Hence, while they had secured in 1819 the cession from Spain to the United States of the Slave-holding Floridas, and the organization of the Slave Territory of Florida in 1822—which subsequently came in as a Slave State under the same Act (1845) that admitted the Free State of Iowa—their greedy eyes were now cast upon the adjoining rich territories of Mexico.
Efforts had (in 1827-1829) been made to purchase from Mexico the domain which was known as Texas. They had failed. But already a part of Texas had been settled by adventurous Americans under Mexican grants and otherwise; and General Sam Houston, an adherent of the Slave Power, having become a leading spirit among them, fomented a revolution. In March, 1836, Texas, under his guidance, proclaimed herself a Republic independent of Mexico.
The War that ensued between Texas and Mexico ended in the flight of the Mexican Army and the capture of Santa Anna at San Jacinto, and a treaty recognizing Texan independence. In October, 1836, General Houston was inaugurated President of the Republic of Texas. Close upon this followed (in August, 1837) a proposition to our Government from the Texan envoy for the annexation of Texas to the United States. President Van Buren declined the offer. The Northern friends of Freedom were as much opposed to this annexation project as the advocates of Slavery were anxious for it. Even such conservative Northern Statesmen as Daniel Webster strongly opposed the project. In a speech delivered in New York, after showing that the chief aim of our Government in the acquisition of the Territory of Louisiana was to gain command of the mouths of the great rivers to the sea, and that in the acquisition of the Floridas our policy was based on similar considerations, Mr. Webster declared that "no such necessity, no such policy, requires the annexation of Texas," and that we ought "for numerous and powerful reasons to be content with our present boundaries." He recognized that Slavery already existed under the guarantees of the Constitution and those guarantees must be fulfilled; that "Slavery, as it exists in the States, is beyond the power of Congress. It is a concern of the States themselves," but "when we come to speak of admitting new States, the subject assumes an entirely different aspect. Our rights and our duties are then both different. The Free States, and all the States, are then at liberty to accept or to reject;" and he added, "In my opinion the people of the United States will not consent to bring into the Union a new, vastly extensive and Slaveholding country, large enough for a half a dozen or a dozen States. In my opinion, they ought not to consent to it."
Farther on, in the same speech—after alluding to the strong feeling in the Northern States against the extension of Slavery, not only as a question of politics, but of conscience and religious conviction as wellhe deems him a rash man indeed "who supposes that a feeling of this kind is to be trifled with or despised." Said he: "It will assuredly cause itself to be respected. It may be reasoned with; it may be made willing—I believe it is entirely willing—to fulfill all existing engagements and all existing duties—to uphold and defend the Constitution as it is established, with whatever regrets about some provisions which it does actually contain. But to coerce it into silence, to endeavor to restrain its free expression, to seek to compress and confine it, warm as it is, and more heated as such endeavors would inevitably render it,—should this be attempted, I know nothing, even in the Constitution or in the Union itself, which would not be endangered by the explosion which might follow."
In 1840, General Harrison, the Whig candidate, was elected to the Presidency, but died within a few weeks after his inauguration in 1841, and was succeeded by John Tyler. The latter favored the Slave Power; and on April 12th, 1844, John C. Calhoun, his Secretary of State, concluded with Texas a treaty of annexation—which was, however, rejected by the Senate. Meanwhile the public mind was greatly agitated over the annexation and other, questions.9
Threats and counter-threats of Disunion were made on either hand by the opponents and advocates of Slavery-extension through annexation; nor was it less agitated on the subject of a Protective Tariff.
The Compromise Tariff of 1833, together with President Jackson's upheaval of our financial system, produced, as has already been hinted, terrible commercial disasters. "In 1840," says competent authority, "all prices had ruinously fallen; production had greatly diminished, and in many departments of industry had practically ceased; thousands of working men were idle, with no hope of employment, and their families suffering from want. Our farmers were without markets, their products rotted in their barns, and their lands, teeming with rich harvests, were sold by the sheriff for debts and taxes. The Tariff, which robbed our industries of Protection failed to supply Government with its necessary revenues. The National Treasury in consequence was bankrupt, and the credit of the Nation had sunk very low."
Mr. Clay himself stated "the average depression in the value of property under that state of things which existed before the Tariff of 1842 came to the rescue of the country, at fifty per cent." And hence it was that Protection was made the chief issue of the Presidential campaign of 1840, which eventuated in the election of Harrison and Tyler, and in the Tariff Act of August 30, 1842, which revived our trade and industries, and brought back to the land a full measure of prosperity. With those disasters fresh in the minds of the people, Protection continued to be a leading issue in the succeeding Presidential campaign of 1844—but coupled with the Texas-annexation issue. In that campaign Henry Clay was the candidate of the Whig party and James K. Polk of the Democratic party. Polk was an ardent believer in the annexation policy and stood upon a platform declaring for the "re-occupation of Oregon and the re-annexation of Texas at the earliest practicable moment"—as if the prefix "re" legitimatized the claim in either case; Clay, on the other hand, held that we had "fairly alienated our title to Texas by solemn National compacts, to the fulfilment of which we stand bound by good faith and National honor;" that "Annexation and War with Mexico are identical," and that he was "not willing to involve this country in a foreign War for the object of acquiring Texas."10
As to the Tariff issue also, Clay was the acknowledged champion of the American system of Protection, while Polk was opposed to it, and was supported by the entire Free-trade sentiment, whether North or South.
As the campaign progressed, it became evident that Clay would be elected. Then occurred some of those fatalities which have more than once, in the history of Presidential campaigns, overturned the most reasonable expectations and defeated the popular will. Mr. Clay committed a blunder and Mr. Polk an equivocation—to use the mildest possible term. Mr. Clay was induced by Southern friends to write a letter11 in which, after stating that "far from having any personal objection to the annexation of Texas, I should be glad to see it—without dishonor, without War, with the common consent of the Union, and upon just and fair
