the transfer of interest; the war of 1812 gave a complete protection to infant industries; the dumping of British goods in 1815 stirred patriotic American feeling; British renewal of colonial system restrictions, and the twelve-year quarrel over "retaliation" gave time for the definite establishment of protectionist ideas in the United States. But Britain was soon proclaiming for herself and for the world the common advantage and the justice of a great theory of free trade. America was apparently now committed to an opposing economic theory, the first great nation definitely to establish it, and thus there resulted a clear-cut opposition of principle and a clash of interests. From 1846, when free trade ideas triumphed in England, the devoted British free trader regarded America as the chief obstacle to a world-wide acceptance of his theory. The one bright spot in America, as regarded by the British free trader, was in the Southern States, where cotton interests, desiring no advantage from protection, since their market was in Europe, attacked American protection and sought to escape from it. Also slave supplies, without protection, could have been purchased more cheaply from England than from the manufacturing North. In 1833 indeed the South had forced a reaction against protection, but it proceeded slowly. In 1854 it was Southern opinion that carried through Congress the reciprocity treaty with the British American Provinces, partly brought about, no doubt, by a Southern fear that Canada, bitter over the loss of special advantages in British markets by the British free trade of 1846, might join the United States and thus swell the Northern and free states of the Union. Cotton interests and trade became the dominant British commercial tie with the United States, and the one great hope, to the British minds, of a break in the false American system of protection. Thus both in economic theory and in trade, spite of British dislike of slavery, the export trading interests of Great Britain became more and more directed toward the Southern States of America. Adding powerfully to this was the dependence of British cotton manufactures upon the American supply. The British trade attitude, arising largely outside of direct governmental contacts, was bound to have, nevertheless, a constant and important influence on governmental action. Governmental policy, seeking national power, conflicting trade and industrial interests, are the favourite themes of those historians who regard nations as determined in their relations solely by economic causes--by what is called "enlightened self-interest." But governments, no matter how arbitrary, and still more if in a measure resting on representation, react both consciously and unconsciously to a public opinion not obviously based upon either national or commercial rivalry. Sometimes, indeed, governmental attitude runs absolutely counter to popular attitude in international affairs. In such a case, the historical estimate, if based solely on evidences of governmental action, is a false one and may do great injustice to the essential friendliness of a people. How then, did the British people, of all classes, regard America before
