Meanwhile, after a longer and stiffer resistance, Japan had made up her mind to a great change with amazing suddenness and completeness. There had been some preliminary relations with the Western peoples, beginning with the visits of the American Commodore Perry in 1853 and 1854, and a few ports had been opened to European trade. But then came a sudden, violent reaction (1862). The British embassy was attacked; a number of British subjects were murdered; a mixed fleet of British, French, Dutch, and American ships proved the power of Western arms, and Japan began to awaken to the necessity of adopting, in self-defence, the methods of these intrusive foreigners. The story of the internal revolution in Japan, which began in 1866, cannot be told here; enough that it led to the most astounding change in history. Emerging from her age-long isolation and from her contentment with her ancient, unchanging modes of life, Japan realised that the future lay with the restless and progressive civilisation of the West; and with a national resolve to which there is no sort of parallel or analogy in history, decided that she must not wait to be brought under subjection, but must adopt the new methods and ideas for herself, if possible without shedding too much of her ancient traditions. By a deliberate exercise of the will and an extraordinary effort of organisation, she became industrial without ceasing to be artistic; she adopted parliamentary institutions without abandoning her religious veneration for the person of the Mikado; she borrowed the military methods of the West without losing the chivalrous and fatalist devotion of her warrior-caste; and devised a Western educational system without disturbing the deep orientalism of her mind. It was a transformation almost terrifying, and to any Western quite bewildering, in its deliberation, rapidity, and completeness. Europe long remained unconvinced of its reality. But in 1878 the work was, in its essentials, already achieved, and the one state of non-European origin which has been able calmly to choose what she would accept and what she would reject among the systems and methods of the West, stood ready to play an equal part with the European nations in the later stages of the long imperial struggle.

One last sphere of activity remains to be surveyed before we turn to consider the development of the new British Empire: the expansion of the independent states which had arisen on the ruins of the first colonial empires in the New World. Of the Spanish and Portuguese states of Central and South America it is not necessary to say much. They had established their independence between 1815 and 1825. But the unhappy traditions of the long Spanish ascendancy had rendered them incapable of using freedom well, and Central and South America became the scene of ceaseless and futile revolutions. The influence of the American Monroe Doctrine forbade, perhaps fortunately, the intervention of any of the European states to put an end to this confusion, and America herself made no serious attempt to restrain it. It was not until the later years of our period that any large stream of immigration began to flow into these lands from other European countries than Spain and Portugal, and that their vast natural resources began to be developed by the energy and capital of Europe. But by 1878 the more fertile of these states, Argentina, Brazil, and Chili, were being enriched by these means, were becoming highly important elements in the trade-system of the world, and were consequently beginning to achieve a more stable and settled civilisation. In some regards this work (though it belongs mainly to the period after 1878) constitutes one of the happiest results of the extra-European activities of the European peoples during the nineteenth century. It was carried on, in the main, not by governments or under government encouragement, but by the private enterprises of merchants and capitalists; and while a very large part in these enterprises was played by British and American traders and settlers, one of the most notable features of the growth of South America was that it gave play to some of the European peoples, notably the Germans and the Italians, whose part in the political division of the world was relatively small.

Far more impressive was the almost miraculous expansion which came to the United States during this period. When the United States started upon their career as an independent nation in 1782, their territory was limited to the lands east of the Mississippi, excluding Florida, which was still retained by Spain. Only the eastern margin of this area was at all fully settled; and the population numbered at most 2,000,000, predominantly of British blood. In 1803, by a treaty with Napoleon, the French colony of Louisiana, with vast and ill-defined claims to the territory west of the Mississippi, was purchased from France. Meanwhile the stream of immigrants from the eastern states, and in a less degree from Europe, was pouring over the Alleghany Mountains and occupying the great central plain; and by 1815 the population had risen to almost 9,000,000, still mainly of British stock, though it also included substantial French and German elements, as well as large numbers of negro slaves. In 1819 Florida was acquired by purchase from Spain. In 1845-48 a revolution in Texas (then part of Mexico), followed by two Mexican wars, led to the annexation of a vast area extending from the Gulf of Mexico to the Pacific coast, including the paradise of California; while treaties with Britain in 1818 and 1846 determined the northern boundary of the States, and secured their control over the regions of Washington and Oregon.

Thus the imperialist spirit was working as irresistibly in the democratic communities of the New World as in the monarchies of Europe. Not content with the possession of vast and almost unpeopled areas, they had spread their dominion from ocean to ocean, and built up an empire less extensive indeed than that of Russia, but even more compact, far richer in resources, and far better suited to be the home of a highly civilised people. Into this enormous area there began to pour a mighty flood of immigration from Europe, as soon as the Napoleonic wars were over. By 1878 the population of the States had risen to about 50,000,000, and was greater than that of any European state save Russia. A new world-state of the first rank had arisen. It was made up of contributions from all the European peoples. Those of British stock, especially the Irish, still predominated throughout this period, but the Germans and the Scandinavians were becoming increasingly numerous, and the Italians, Greeks, Poles, Czechs, Russian Jews, and other stocks were beginning to form very substantial elements. It was a melting-pot of races, which had to be somehow welded into a nation by the moulding-power of the traditions implanted by the earlier British settlers. It may fairly be said that no community has ever had imposed upon it a more difficult task than the task imposed by Fate upon the American people of creating a national unity out of this heterogeneous material. The great experiment was, during this period, singularly successful. The strength of the national sentiment and of the tradition of freedom was very powerfully exhibited in the strain of the great Civil War (1861-65) which maintained at a great cost the threatened unity of the republic, and brought about the emancipation of the negro slaves. And the Civil War produced in Abraham Lincoln a national hero, and an exponent of the national character and ideals, worthy to be set beside Washington. The America of Lincoln manifestly stood for Liberty and Justice, the fundamental ideals of Western civilisation.

But in this great moulding tradition of freedom there was one dubious and narrowing element. Accustomed to regard herself as having achieved liberty by shaking off her connection with the Old World, America was tempted to think of this liberty as something peculiar to herself, something which the 'effete monarchies' of the Old World did not, and could not, fully understand or share, something which exempted her from responsibility for the non-American world, and from the duty of aiding and defending liberty beyond her own limits. In the abounding prosperity of this fortunate land, liberty was apt to be too readily identified merely with the opportunity of securing material prosperity, and the love of liberty was apt to become, what indeed it too often is everywhere, a purely self-regarding emotion. The distance of the republic from Europe and its controversies, its economic self-sufficiency, its apparent security against all attack, fostered and strengthened this feeling. While the peoples of the Old World strove with agony and travail towards freedom and justice, or wrestled with the task of sharing their own civilisation with the backward races of the globe, the echo of their strivings penetrated but faintly into the mind of America, like the noises of the street dimly heard through the shuttered windows of a warmed and lighted room. To the citizens of the Middle West and the Far West, especially, busy as they were with the development of vast untapped resources, the affairs of the outer world necessarily appeared remote and insignificant. Even their newspapers told them little about these far-off events. Naturally it appeared that the function of the republic in the progress of the world was to till its own garden, and to afford a haven of refuge to the oppressed and impoverished who poured in from all lands; and this idea was strengthened by the great number of immigrants who were driven to the New World by the failure of the successive European revolutions of the nineteenth century, and by the oppressive tyranny of the Habsburg monarchy and the Russian despots.

This attitude of aloofness from, and contempt, or, at the best, indifference, to the Old World was further encouraged by the traditional treatment of American history. The outstanding event of that story was, of course, the breach with Britain, with which the independent existence of the Republic began, and which constituted also almost its only direct contact with the politics of the Old World. The view of this conflict which was driven into the national mind by the school-books, by the annual celebrations of the Fourth of July, and by incessant newspaper writing, represented the great quarrel not as a dispute in a family of free communities, in which a new and very difficult problem was raised, and in which there were faults on both sides, but as one in which all the right was on one side, as a heroic resistance of free men against malevolent tyranny. This view has been profoundly modified by the work of American historians, whose researches during the last generation have transformed the treatment of the American Revolution. To-day the old one-sided view finds expression, in books of serious pretensions, only in England; and it is to American scholars that we must have recourse for a more scientific and impartial treatment. But the new and saner view has scarcely yet made its way into the school-books and the newspapers. If Britain, the mother of political liberty in the modern world, the land from which these freemen had inherited their own liberties and the spirit which made them insist upon their enlargement, was made to appear a tyrant power, how could it be expected that the mass of Americans, unversed in world-politics, should follow with sympathy the progress of liberty beyond the limits of their own republic? It was in the light of this traditional attitude that the bulk of Americans regarded not only the wars and controversies of Europe, but the vast process of European expansion. All these things did not appear to concern them; they seemed to be caused by motives and ideas which the great republic had outgrown, though, as we have already seen, and shall see again, the republic had by no means outgrown them. The strength of this traditional attitude, fostered as it was by every circumstance, naturally made the bulk of the American people slow to realise, when the great challenge of Germany was forced upon the world, that the problems of world-politics were as vitally important for them as for all other peoples, and that no free nation could afford to be indifferent to the fate of liberty upon the earth.

At one moment, indeed, almost at the beginning of the period, it appeared as if this narrow outlook was about to be abandoned. The League of Peace of the great European powers of 1815[6] had, by 1822, developed into a league of despots for the suppression of revolutionary tendencies. They had intervened to crush revolutionary outbreaks in Naples and Piedmont; they had authorised France to enter Spain in order to destroy the democratic system which had been set up in that country in 1820. Britain alone protested against these interventions, claiming that every state ought to be left free to fix its own form of government; and in 1822 Canning had practically withdrawn from the League of Peace, because it was being turned into an engine of oppression. It was notorious that, Spain once subjugated, the monarchs desired to go on to the reconquest of the revolting Spanish colonies in South America. Britain could not undertake a war on the Continent against all the Continental powers combined, but she could prevent their intervention in America, and Canning made it plain that the British fleet would forbid any such action. To strengthen his hands, he suggested to the American ambassador that the United States might take common action in this sense. The result was the famous message of President Monroe to Congress in December 1823, which declared that the United States accepted the doctrine of non-intervention, and that they would resist any attempt on the part of the European monarchs to establish their reactionary system in the New World.

In effect this was a declaration of support for Britain. It was so regarded by Monroe's most influential adviser, Thomas Jefferson. 'Great Britain,' he wrote, 'is the nation which can do us the most harm of any one, or all, on earth, and with her on our side we need not fear the whole world. With her, then, we should the most sedulously cherish a cordial friendship; and nothing would tend more to knit our affection than to be fighting once more side by side hi the same cause.' To be fighting side by side with Britain in the same cause—the cause of the secure establishment of freedom in the world—this seemed to the Democrat Jefferson an object worth aiming at; and the promise of this seemed to be the main recommendation of the Monroe Doctrine. It was intended as an alliance for the defence of freedom, not as a proclamation of aloofness; and thus America seemed to be taking her natural place as one of the powers concerned to strengthen law and liberty, not only within her own borders, but throughout the world.

The Monroe Doctrine was rapidly accepted as expressing the fundamental principle of American foreign policy. But under the influence of the powerful tradition which we have attempted to analyse, its significance was gradually changed; and instead of being interpreted as a proclamation that the great republic could not be indifferent to the fate of liberty, and would co-operate to defend it from attack in all cases where such co-operation was reasonably practicable, it came to be interpreted by average public opinion as meaning that America had no concern with the politics of the Old World, and that the states of the Old World must not be allowed to meddle in any of the affairs of either American continent. The world of civilisation was to be divided into water-tight compartments; as if it were not indissolubly one. Yet even in this rather narrow form, the Monroe doctrine has on the whole been productive of good; it has helped to save South America from becoming one of the fields of rivalry of the European powers.
