But the most powerful constructive element in the shaping of the new imperial policy of Britain was the strength of the belief in the idea of self-government, as not only morally desirable but practically efficacious, which was to be perceived at work in the political circles of Britain during this age. Self-government had throughout the modern age been a matter of habit and practice with the British peoples; now it became a matter of theory and belief. And from this resulted a great change of attitude towards the problems of colonial administration. The American problem in the eighteenth century had arisen ultimately out of the demand of the Americans for unqualified and responsible control over their own affairs: the attitude of the Englishman in reply to this demand (though he never clearly analysed it) was, in effect, that self-government was a good and desirable thing, but that on the scale on which the Americans claimed it, it would be fatal to the unity of the Empire, and the unity of the Empire must come first. Faced by similar problems in the nineteenth century, the Englishman's response generally was that self-government on the fullest scale was the right of all who were fit to exercise it, and the most satisfactory working solution of political problems. Therefore the right must be granted; and the unity of the Empire must take care of itself. No doubt this attitude was more readily adopted because of the widespread belief that in fact the colonies would all sooner or later cut their connection with the mother-country. But it was fully shared by men who did not hold this view, and who believed strongly in the possibility and desirability of maintaining imperial unity. It was shared, for example, by Wakefield, a convinced imperialist if ever there was one, and by that great colonial administrator, Sir George Grey. It was shared by Lord Durham and by Lord John Russell, who were largely responsible for the adoption of the new policy. Their belief and hope was that the common possession of free institutions of kindred types would in fact form the most effective tie between the lands which enjoyed them. This hope obtained an eloquent expression in the speech in which, in 1852, Russell introduced the bill for granting to the Australian colonies self-government on such a scale as amounted almost to independence. It is not true, as is sometimes said, that the self-governing institutions of the colonies were established during this period owing to the indifference of the home authorities, and their readiness to put an end to the connection. The new policy of these years was deliberately adopted; and although its acceptance by parliament was rendered easier by the prevalence of disbelief in the permanence of the imperial tie, yet, on the part of the responsible men, it was due to far-sighted statesmanship.

The critical test of the new colonial policy, and the most dramatic demonstration of its efficacy, were afforded by Canada, where, during the thirties, the conditions which preceded the revolt of the American colonies were being reproduced with curious exactness. The self-governing institutions established in the Canadian colonies in 1791 very closely resembled those of the American colonies before the revolution: they gave to the representative houses control over taxation and legislation, but neither control over, nor responsibility for, the executive. And the same results were following. Incomplete self-government was striving after its own fulfilment: the denial of responsibility was producing irresponsibility. These was the same unceasing friction between governors and their councils on the one hand, and the representative bodies on the other hand; and the assemblies were showing the same unreasonableness in refusing to meet manifest public obligations. This state of things was becoming steadily more acute in all the colonies, but it was at its worst in the province of Quebec, where the constitutional friction was embittered by a racial conflict, the executive body being British, while the great majority of the assembly was French; and the conflict was producing a very dangerous alienation between the two peoples. The French colonists had quite forgotten the gratitude they had once felt for the maintenance of their religion and of their social organisation, and there was a strong party among them who were bent upon open revolt, and hoped to be able to establish a little isolated French community upon the St. Lawrence. This party of hotheads got the upper hand, and their agitation culminated in the rebellion of Papineau in 1837. In the other colonies, and especially in Upper Canada, the conditions were almost equally ominous; when Papineau revolted in Quebec, William Mackenzie led a sympathetic rising in Ontario. The situation was quite as alarming as the situation in the American colonies had been in 1775. It is true that the risings were easily put down. But mere repression formed no solution, any more than a British victory in 1775 would have formed a solution of the American question.

Realising this, the Whig government sent out Lord Durham, one of their own number, to report on the whole situation. Durham was one of the most advanced Liberals in Britain, a convinced believer in the virtues of self-government, and he took out with him two of the ablest advocates of scientific colonisation, Edward Gibbon Wakefield and Charles Buller. Durham's administrative work was not a success: his high-handed deportation of some of the rebel leaders was strongly condemned, and he was very quickly recalled. But he had had time to study and understand the situation, and he presented a masterly Report on Canada, which is one of the classics in the history of British imperialism. His explanation of the unhappy condition of Canadian politics was not (as some were tempted to say) that the colonists had been given too much liberty, but that they had not been given enough. They must be made to feel their responsibility for the working of the laws which they adopted, and for the welfare of the whole community. As for the conflict of races, its only cure was that both should be made to feel their common responsibility for the destinies of the community in which both must remain partners.

Lord Durham's recommendations were fully carried into effect, partly in the Canada Act of 1840, but more especially by a simple instruction issued to governors, that their ministries must henceforward be chosen, in the British fashion, on the ground that they commanded the support of a majority in the elected house; and that the governors themselves must be guided by their advice. A crucial test of this new policy came in 1849, when the ministers and the parliamentary majority proposed to vote compensation for property destroyed in 1837. This to many seemed compensation for rebels, and the indignant loyalists were urgent that the governor, Lord Elgin, should veto it. He firmly declined to do so; and thus gave an invaluable lesson to both parties. The Canadian people, acting through their representatives, were now responsible for their actions. If they chose to vote for irresponsible and dangerous devices, they must henceforward realise that they must themselves answer for the consequences.

Thus, within a few years of the outbreak of rebellion in two provinces, full power had been entrusted to the rebels themselves. It was a daring policy, only to be justified by a very confident belief in the virtues of self-government. But it was completely and triumphantly successful. Henceforward friction between the Canadian colonies and the mother-country ceased: if there were grounds for complaint in the state of Canadian affairs, the Canadians must now blame their own ministers, and the remedy lay in their own hands. And what was the outcome? Twenty years later the various colonies, once as full of mutual jealousies as the American colonies had been before 1775, began to discuss the possibility of federation. With the cordial approval and co-operation of the home government, they drew up a scheme for the formation of a united Dominion of Canada, including distant British Columbia and the coastal colonies of Nova Scotia, New Brunswick, and Prince Edward Island; and the adoption of this scheme, in 1867, turned Canada from a bundle of separate settlements into a great state. To this state the home government later made over the control of all the vast and rich lands of the North-West, and so the destinies of half a continent passed under its direction. It was a charge, the magnitude and challenge of which could not but bring forth all that there was of statesmanship among the Canadian people; and it has not failed to do so.

One feature of Canadian constitutional development remains to be noted. It might have been expected that the Canadians would have been tempted to follow the political model of their great neighbour the United States; and if their development had been the outcome of friction with the mother-country, no doubt they would have done so. But they preferred to follow the British model. The keynote of the American system is division of power: division between the federal government and the state governments, which form mutual checks upon one another; division between the executive and the legislature, which are independent of one another at once in the states and in the federal government, both being directly elected by popular vote. The keynote of the British system is concentration of responsibility by the subordination of the executive to the legislature. The Canadians adopted the British principle: what had formerly been distinct colonies became, not 'states' but 'provinces,' definitely subordinated to the supreme central government; and whether in the federal or in the provincial system, the control of government by the representative body was finally established. This concord with the British system is a fact of real import. It means that the political usages of the home-country and the great Dominion are so closely assimilated that political co-operation between them is far easier than it otherwise might be; it increases the possibility of a future link more intimate than that of mere co-operation.

Not less whole-hearted or generous than the treatment of the problems of Canadian government was the treatment of the same problem in Australia. Here, as a matter of course, all the colonies had been endowed, at the earliest possible date, with the familiar system of representative but not responsible government. No such acute friction as had occurred in Canada had yet shown itself, though signs of its development were not lacking. But in 1852 an astonishing step was taken by the British parliament: the various Australian colonies were empowered to elect single-chamber constituent assemblies to decide the forms of government under which they wished to live. They decided in every case to reproduce as nearly as possible the British system: legislatures of two chambers, with ministries responsible to them. Thus, in Australia as in Canada, the daughter-peoples were made to feel the community of their institutions with those of the mother-country, and the possibility of intimate and easy co-operation was increased. Two years later, in 1854, New Zealand was endowed with the same system. Among all the British realms in which the white man was predominant, only South Africa was as yet excluded from this remarkable development. The reasons for this exclusion we have already noted: its consequences will occupy our attention in later pages.

Very manifestly the empire which was developing on such lines was not an empire in the old sense—a dominion imposed by force upon unwilling subjects. That old word, which has been used in so many senses, was being given a wholly new connotation. It was being made to mean a free partnership of self-governing peoples, held together not by force, but in part by common interests, and in a still higher degree by common sentiment and the possession of the same institutions of liberty.

In the fullest sense, however, this new conception of empire applied only to the group of the great self-governing colonies. There were many other regions, even before 1878, included within the British Empire, though as yet it had not incorporated those vast protectorates over regions peopled by backward races which have been added during the last generation. There were tropical settlements like British Honduras, British Guiana, Sierra Leone, and Cape Coast Castle; there were many West Indian Islands, and scattered possessions like Mauritius and Hong-Kong and Singapore and the Straits Settlements; there were garrison towns or coaling-stations like Gibraltar, Malta, Aden, St. Helena. To none of these were the institutions of full responsible self-government granted. Some of them possessed representative institutions without responsible ministries; in others the governor was assisted by a nominated council, intended to express local opinion, but not elected by the inhabitants; in yet others the governor ruled autocratically. But in all these cases the ultimate control of policy was retained by the home government. And in this general category, as yet, the South African colonies were included. Why were these distinctions drawn? Why did the generation of British statesmen, who had dealt so generously with the demand for self-government in Canada and Australia, stop short and refuse to carry out their principles in these other cases?

It is characteristic of British politics that they are never merely or fully logical, and that even when political doctrines seem to enjoy the most complete ascendancy, they are never put into effect without qualifications or exceptions. The exceptions already named to the establishment of full self-government were due to many and varying causes. In the first place, there was in most of these cases no effective demand for full self-government; and it may safely be asserted that any community in which there is no demand for self-governing institutions is probably not in a condition to work them with effect. Some of these possessions were purely military posts, like Gibraltar and Aden, and were necessarily administered as such. Others were too small and weak to dream of assuming the full privileges. But in the majority of cases one outstanding common feature will appear on closer analysis. Nearly all these territories were tropical or semi-tropical lands, whose British inhabitants were not permanent settlers, but were present solely for the purposes of trade or other exploitation, while the bulk of the population consisted of backward peoples, whose traditions and civilisation rendered their effective participation in public affairs quite impracticable. In such cases, to have given full political power to the small and generally shifting minority of white men would have been to give scope to many evils; and to have enfranchised, on a mere theory, the mass of the population would have been to produce still worse results. It would have sentenced these communities to the sort of fate which has befallen the beautiful island of Hayti, where the self-government of a population of emancipated negro slaves has brought nothing but anarchy and degradation. In such conditions the steady Reign of Law is the greatest boon that can be given to white settlers and coloured subjects alike; and the final authority is rightly retained by the home government, inspired, as British opinion has long required that it should be, by the principle that the rights of the backward peoples must be safeguarded. Under this system, both law and a real degree of liberty are made possible; whereas under a doctrinaire application of the theory of self-government, both would vanish.
