But, though Calhoun's motive was probably the political strengthening of the South, his Texan policy could find plenty of support in every part of the Union. Most Northerners, especially in the new States of the North-West, cared more for the expansion of the United States than for the sectional jealousies. They were quite prepared to welcome Texas into the Union; but, unfortunately for Calhoun, they had a favourite project of expansion of their own for which they expected a corresponding support.
The whole stretch of the Pacific slope which intervenes between Alaska and California, part of which is now represented by the States of Washington and Oregon and part by British Columbia, was then known generally as "Oregon." Its ownership was claimed both by British and American Governments upon grounds of prior exploration, into the merits of which it is hardly necessary to enter here. Both claims were in fact rather shadowy, but both claimants were quite convinced that theirs was the stronger. For many years the dispute had been hung up without being settled, the territory being policed jointly by the two Powers. Now, however, there came from the Northern expansionists a loud demand for an immediate settlement and one decidedly in their favour. All territory south of latitude 47° 40' must be acknowledged as American, or the dispute must be left to the arbitrament of arms. "Forty-seven-forty or fight!" was the almost unanimous cry of the Democracy of the North and West.
The Secretary of State set himself against the Northern Jingoes, and though his motives may have been sectional, his arguments were really unanswerable. He pointed out that to fight England for Oregon at that moment would be to fight her under every conceivable disadvantage. An English army from India could be landed in Oregon in a few weeks. An American army sent to meet it must either round Cape Horn and traverse the Atlantic and Pacific oceans in the face of the most powerful navy in the world or march through what was still an unmapped wilderness without the possibility of communications or supports. If, on the other hand, the question were allowed to remain in suspense, time would probably redress the balance in favour of the United States. American expansion would in time touch the borders of Oregon, and then the dispute could be taken up and settled under much more favourable circumstances. It was a perfectly just argument, but it did not convince the "forty-seven-forty-or-fighters," who roundly accused the Secretary—and not altogether unjustly—of caring only for the expansion of his own section.
Calhoun was largely instrumental in averting a war with England, but he did not otherwise conduct himself in such a manner as to conciliate opinion in that country. England, possibly with the object of strengthening her hand in bargaining for Oregon, had intervened tentatively in relation to Texas. Lord Aberdeen, then Peel's Foreign Secretary, took up that question from the Anti-Slavery standpoint, and expressed the hope that the prohibition of Slavery by Mexico would not be reversed if Texas became part of the American Union. The intervention, perhaps, deserved a snub—for, after all, England had only recently emancipated the slaves in her own colonies—and a sharp reminder that by the Monroe Doctrine, to which she was herself a consenting party, no European Power had a right to interfere in the domestic affairs of an American State. Calhoun did not snub Lord Aberdeen: he was too delighted with his lordship for giving him the opportunity for which he longed. But he did a thing eminently characteristic of him, which probably no other man on the American continent would have done. He sat down and wrote an elaborate and very able State Paper setting forth the advantages of Slavery as a foundation for civilization and public liberty. It was this extraordinary dispatch that led Macaulay to say in the House of Commons that the American Republic had "put itself at the head of the nigger-driving interest throughout the world as Elizabeth put herself at the head of the Protestant interest." As regards Calhoun the charge was perfectly true; and it is fair to him to add that he undoubtedly believed in Slavery much more sincerely than ever Elizabeth did in Protestantism. But he did not represent truly the predominant feeling of America. Northern Democratic papers, warmly committed to the annexation of Texas, protested vehemently against the Secretary's private fad concerning the positive blessedness of Slavery being put forward as part of the body of political doctrine held by the United States. Even Southerners, who accepted Slavery as a more or less necessary evil, did not care to see it thus blazoned on the flag. But Calhoun was impenitent. He was proud of the international performance, and the only thing he regretted, as his private correspondence shows, was that Lord Aberdeen did not continue the debate which he had hoped would finally establish his favourite thesis before the tribunal of European opinion.
Texas was duly annexed, and Tyler's Presidency drew towards its close. He seems to have hoped that the Democrats whom he had helped to defeat in 1840 would accept him as their candidate for a second term in 1844; but they declined to do so, nor did they take kindly to the suggestion of nominating Calhoun. Instead, they chose one Polk, who had been a stirring though not very eminent politician in Jacksonian days. The choice is interesting as being the first example of a phenomenon recurrent in subsequent American politics, the deliberate selection of a more or less obscure man on the ground of what Americans call "availability."
It is the product of the convergence of two things—the fact of democracy as indicated by the election of a First Magistrate by a method already frankly plebiscitary, and the effect of a Party System, becoming, as all Party Systems must become if they endure, at once increasingly rigid and increasingly unreal.
The aim of party managers—necessarily professionals—was to get their party nominee elected. But the conditions under which they worked were democratic. They could not, as such professionals can in an oligarchy like ours, simply order the electors to vote for any nincompoop who was either rich and ambitious enough to give them, the professionals, money in return for their services, or needy and unscrupulous enough to be their hired servant. They were dealing with a free people that would not have borne such treatment. They had to consider as a practical problem for what man the great mass of the party would most readily and effectively vote. And it was often discovered that while the nomination of an acknowledged "leader" led, through the inevitable presence (in a democracy) of conflicts and discontents within the party, to the loss of votes, the candidate most likely to unite the whole party was one against whom no one had any grudge and who simply stood for the "platform" which was framed in a very democratic fashion by the people themselves voting in their "primaries." When this system is condemned and its results held up to scorn, it should be remembered that among other effects it is certainly responsible for the selection of Abraham Lincoln.
Polk was not a Lincoln, but he was emphatically an "available" candidate, and he won, defeating Clay, to whom the Whigs had once more reverted, by a formidable majority. He found himself confronted with two pressing questions of foreign policy. During the election the Democrats had played the "Oregon" card for all it was worth, and the new President found himself almost committed to the "forty-seven-forty-or-fight" position. But the practical objections to a war with England on the Oregon dispute were soon found to be just as strong as Calhoun had represented them to be. Moreover, the opportunity presented itself for a war at once much more profitable and much less perilous than such a contest was likely to prove, and it was obvious that the two wars could not be successfully undertaken at once.
The independence of Texas had been in some sort recognized by Mexico, but the frontier within which that independence formally existed was left quite undefined, and the Texan view of it differed materially from the Mexican. The United States, by annexing Texas, had shouldered this dispute and virtually made it their own.
It is seldom that historical parallels are useful; they are never exact. But there are certain real points of likeness between the war waged by the United States against Mexico in the 'forties and the war waged by Great Britain against the Boer Republics between 1899 and 1902. In both cases it could be plausibly represented that the smaller and weaker Power was the actual aggressor. But in both cases there can be little doubt that it was the stronger Power which desired or at least complacently contemplated war. In both cases, too, the defenders of the war, when most sincere, tended to abandon their technical pleas and to take their stand upon the principle that the interests of humanity would best be served by the defeat of a "backward" people by a more "progressive" one. It is not here necessary to discuss the merits of such a plea. But it may be interesting to note the still closer parallel presented by the threefold division of the opposition in both cases. The Whig Party was divided in 1847, almost exactly as was the "Liberal" Party in 1899. There was, especially in New England, an ardent and sincere minority which was violently opposed to the war and openly denounced it as an unjustifiable aggression. Its attitude has been made fairly familiar to English readers by the first series of Lowell's "Bigelow Papers." This minority corresponded roughly to those who in England were called "Pro-Boers." There was another section which warmly supported the war: it sought to outdo the Democrats in their patriotic enthusiasm, and to reap as much of the electoral harvest of the prevalent Jingoism as might be. Meanwhile, the body of the party took up an intermediate position, criticized the diplomacy of the President, maintained that with better management the war might have been avoided, but refused to oppose the war outright when once it had begun, and concurred in voting supplies for its prosecution.
