Now it was unavoidable that England should be invited {41} to take part in this Congress, seeing that, but for the assistance given by England, there would never have been a chance for even the Congress of Vienna to make any attempt at the regulation of Europe. Besides, it was well known that Lord Londonderry had been a main instrument in the formation and execution of the plans laid down by the Congress of Vienna, and although England, on that occasion, had not been able to go quite as far as her allies would have wished her to accompany them, yet it was not thought possible to leave England without an invitation to be represented at the Congress of Verona. On the death of Lord Londonderry it was resolved by the English Government to send the Duke of Wellington to Verona. The Duke had never professed any particular ideas of his own with regard to foreign policy, but he was the most loyal of men in obeying the instructions of those who were properly authorized to direct his movements, and in whom he could place his confidence. When Canning consented to accept office the Duke at once put himself into communication with the new Foreign Secretary, and wrote to him from Paris informing Canning of his belief that the Spanish question would be brought, in some shape or other, under the consideration of the Congress, and asking Canning for instructions as to the course which he ought to adopt. Canning despatched a reply to the Duke, one passage of which may be regarded as a full illustration of the new principle which he had determined to establish in England's foreign policy. The words of the great statesman cannot be read with too close an attention. Canning declares that, "If there be a determined project to interfere by force or by menace in the present struggle in Spain, so convinced are his Majesty's Government of the uselessness and danger of any such interference, so objectionable does it appear to them in principle as well as in practical execution, that when the necessity arises—or, I would rather say, when the opportunity offers—I am to instruct your Grace at once frankly and peremptorily to declare that to any such interference, come what may, his Majesty will not be a party."

The Duke of Wellington faithfully obeyed the instructions which had been given to him. He made it clear to the Congress of Verona that England would not sanction any project for the interference of foreign sovereigns with the domestic affairs of Spain. When the Duke found that his arguments and his remonstrances were of no avail, he withdrew from the Congress altogether and left the members of the Holy Alliance to take on themselves the full responsibility of their own policy. Now it would be hardly possible to overrate the importance of the step thus taken by England at a great crisis in the public affairs of Europe. The reign of George the Fourth would be memorable in history if it had been consecrated by nothing but this event. The utter disruption between the old state policy and the new was proclaimed by the instructions which Canning sent to the Duke of Wellington, and which were faithfully carried out by the Duke. No English Government has, in later days, ventured to profess openly any other foreign policy than that announced by Canning. Other ministers in later times may have attempted, now and then, to swerve from it in this direction and in that, and to cover their evasion of it by specious pleas, but the new doctrine set up by Canning has never since his time found avowed apostates among English statesmen. It would have been well if such a principle could have inspired the foreign policy of England in the days when the French Revolution broke out, and if England had then proclaimed that she would be no party to any attempt made by foreign States to prevent the people of France from settling their own systems of government for themselves. Europe might have been saved a series of disastrous wars. France might have been relieved from counter-revolutions, seasons of anarchy, and seasons of military despotism. England might long have had friendly neighbors where even yet she has perhaps only concealed enemies.
The designs of the Holy Alliance soon made themselves manifest. The French Government had brought so much pressure to bear on the feeble King of Spain that he revoked the Constitution which, at a better moment, he had {43} granted to his people. There was an attempt at revolution in Spain, and the attempt was put down by the strong hand with the assistance of France, and the leading rebels were at once conducted to the scaffold. Portugal still kept those free institutions which England had enabled her to preserve, and still retained her sympathy with freedom. Canning soon saw that a part of the policy of the French Government was to bring Portugal also into subjection, and against this danger he provided by a bold announcement of policy. He declared in the House of Commons that if Portugal were, of her own accord, to engage herself in a war with France, the English Government would not feel bound to take any active part in the struggle, but that if the King of Spain were to accept or call in the assistance of the King of France to suppress Portugal, the Government of England would put its armies into the field to maintain its ancient ally. Then there arose a great question concerning the Spanish colonies and possessions across the Atlantic. The policy of France was to enable Spain to reconquer some of her American colonies which had long been withdrawing themselves from their condition of subjection, and the scheme of French statesmen evidently was that Spain would hand over some of her American possessions as a tribute of gratitude to France for the services she had rendered to the cause of absolutism in Spain.
On this question, too, Canning announced to the House of Commons a determination on the part of the English Government which put an effectual stop to this audacious policy. Canning declared that, although Spain had long since lost any real control over her transatlantic colonies, yet if she were to attempt their actual reconquest for herself England, however little in sympathy with such a purpose, might not feel that it was any part of her business to interfere by force of arms. But he went on to tell the House that, if Spain should claim the right to hand over any of those colonies to France as a part of the policy arranged between France and Spain, the English Government would then intervene directly and at once on behalf {44} of the Spanish-American colonies. This was the course of action which Canning described to the House of Commons in an immortal phrase when he told the House "that he had called in the New World to redress the balance of the Old." No words employed by an English minister during the last century have been more often quoted, and none have ever more thoroughly justified themselves in history. The schemes of the French and the Spanish Bourbons were blighted in the bud by Canning's memorable declaration.
[Sidenote: 1822-27—The Monroe Doctrine]
Canning had indeed called in the New World to redress the balance of the Old in a sense more complete than the accepted meaning of his words, at the time, appeared to signify. He had secured for his policy the moral co-operation of the New World's greatest power—the Republic of the United States. It was on the inspiration of Canning that the President of the United States embodied in a message to Congress that declaration of principle which has ever since been known as the Monroe doctrine. President Monroe, who knew well that he was proclaiming no doctrine which his influence and his authority with his country would not enable him to carry out, made known to Congress that it was his intention to warn European sovereigns against the danger of setting up their systems in any part of the New World. The United States, according to President Monroe's declaration, had no idea of interfering with existing systems, but if European sovereigns were to set up governments of their own on any other part of the American continents and against the wishes of the populations, the United States must regard any such attempt as a menace and a danger to the American Republic. This is in substance the meaning of that Monroe doctrine which has often been criticised unfairly or ignorantly on this side of the Atlantic, and its proclamation was undoubtedly due, at the time, to the advice which came from George Canning. President Monroe never meant to say that the Government of the United States had any idea of interfering with British North America or with the Empire of Brazil. The {45} Canadian provinces of Great Britain were, of course, perfectly free to remain a loyal part of the British Empire so long as it suited the interests and the inclinations of the Canadians. If the people of Brazil chose to be governed by an emperor, the United States Government did not assert any right to interfere with their choice. But what the Monroe doctrine did declare was that if any foreign sovereigns attempted to bring liberated American colonies again under their sway, or to set up by force new subject colonies on American shores against the wishes of the populations concerned, the United States must regard such action as a menace and a danger to the American Republic, and must not be expected to look quietly on without any attempt at intervention. This was, in the truest sense, the announcement of a policy of peace, for it frankly made known to the despotic rulers of the Old World what their risk must be if they ventured on the futile experiment of setting up despotic states on the shores of the New World.
It would have been well indeed if European monarchs at a later day had always remembered the warning and rightly estimated its weight. It would have been well for Louis Napoleon if at the zenith of his imperial success he had studied that message of President Monroe and properly interpreted its meaning. Such a course would have prevented him from making his ill-starred attempt to set up a Mexican Empire by the force of French arms on the ruins of a subjugated Mexican Republic. It would have saved him from defeat and disaster, and would have saved the unhappy, ill-advised, and gallant Maximilian, his puppet emperor, from a tragic fate. The attempt to retrieve the disgrace of his enforced withdrawal from Mexico led Louis Napoleon into that policy of the desperate gambler's last throw which ended in the occupation of Paris and the fall of the Second Empire.
Meanwhile the policy of Canning had accomplished its purpose. The Congress of Verona had been an idle piece of business, the sovereigns of the Holy Alliance had found that their day was done, and the New World had been successfully called in to redress the balance of the Old.
