Times urged the government to "finish with Mr. Bonaparte and then deal with Mr. Madison and democracy," arguing that it should be England's object to subvert "the whole system of the Jeffersonian school." But this was not the purpose of the British Government, nor would such a purpose have been tolerated by the small but vigorous Whig minority in Parliament.

The peace of 1814, signed at Ghent, merely declared an end of the war, quietly ignoring all the alleged causes of the conflict. Impressment was not mentioned, but it was never again resorted to by Great Britain upon American ships. But the principle of right of search in time of peace, though for another object than impressment, was soon again asserted by Great Britain and for forty years was a cause of constant irritation and a source of danger in the relations of the two countries. Stirred by philanthropic emotion Great Britain entered upon a world crusade for the suppression of the African Slave Trade. All nations in principle repudiated that trade and Britain made treaties with various maritime powers giving mutual right of search to the naval vessels of each upon the others' merchant vessels. The African Slave Trade was in fact outlawed for the flags of all nations. But America, smarting under the memory of impressment injuries, and maintaining in any case the doctrine that in time of peace the national flag protected a vessel from interference or search by the naval vessels of any other power, refused to sign mutual right of search treaties and denied, absolutely, such a right for any cause whatever to Great Britain or to any other nation. Being refused a treaty, Britain merely renewed her assertion of the right and continued to exercise it.

Thus the right of search in time of peace controversy was not ended with the war of 1812 but remained a constant sore in national relations, for Britain alone used her navy with energy to suppress the slave trade, and the slave traders of all nations sought refuge, when approached by a British naval vessel, under the protection of the American flag. If Britain respected the flag, and sheered off from search, how could she stop the trade? If she ignored the flag and on boarding found an innocent American vessel engaged in legal trade, there resulted claims for damages by detention of voyage, and demands by the American Government for apology and reparation. The real slave trader, seized under the American flag, never protested to the United States, nor claimed American citizenship, for his punishment in American law for engaging in the slave trade was death, while under the law of any other nation it did not exceed imprisonment, fine and loss of his vessel.

Summed up in terms of governmental attitude the British contention was that here was a great international humanitarian object frustrated by an absurd American sensitiveness on a point of honour about the flag. After fifteen years of dispute Great Britain offered to abandon any claim to a right of search, contenting herself with a right of visit, merely to verify a vessel's right to fly the American flag. America asserted this to be mere pretence, involving no renunciation of a practice whose legality she denied. In 1842, in the treaty settling the Maine boundary controversy, the eighth article sought a method of escape. Joint cruising squadrons were provided for the coast of Africa, the British to search all suspected vessels except those flying the American flag, and these to be searched by the American squadron. At once President Tyler notified Congress that Great Britain had renounced the right of search. Immediately in Parliament a clamour was raised against the Government for the "sacrifice" of a British right at sea, and Lord Aberdeen promptly made official disclaimer of such surrender.

Thus, heritage of the War of 1812 right of search in time of peace was a steady irritant. America doubted somewhat the honesty of Great Britain, appreciating in part the humanitarian purpose, but suspicious of an ulterior "will to rule the seas." After 1830 no American political leader would have dared to yield the right of search. Great Britain for her part, viewing the expansion of domestic slavery in the United States, came gradually to attribute the American contention, not to patriotic pride, but to the selfish business interests of the slave-holding states. In the end, in 1858, with a waning British enthusiasm for the cause of slave trade suppression, and with recognition that America had become a great world power, Britain yielded her claim to right of search or visit, save when established by Treaty. Four years later, in 1862, it may well have seemed to British statesmen that American slavery had indeed been the basic cause of America's attitude, for in that year a treaty was signed by the two nations giving mutual right of search for the suppression of the African Slave Trade. In fact, however, this was but an effort by Seward, Secretary of State for the North, to influence British and European opinion against the seceding slave states of the South.

The right of search controversy was, in truth, ended when American power reached a point where the British Government must take it seriously into account as a factor in general world policy. That power had been steadily and rapidly advancing since 1814. From almost the first moment of established independence American statesmen visualized the separation of the interests of the western continent from those of Europe, and planned for American leadership in this new world. Washington, the first President, emphasized in his farewell address the danger of entangling alliances with Europe. For long the nations of Europe, immersed in Continental wars, put aside their rivalries in this new world. Britain, for a time, neglected colonial expansion westward, but in 1823, in an emergency of European origin when France, commissioned by the great powers of continental Europe, intervened in Spain to restore the deposed Bourbon monarchy and seemed about to intervene in Spanish America to restore to Spain her revolted colonies, there developed in Great Britain a policy, seemingly about to draw America and England into closer co-operation. Canning, for Britain, proposed to America a joint declaration against French intervention in the Americas. His argument was against the principle of intervention; his immediate motive was a fear of French colonial expansion; but his ultimate object was inheritance by Britain of Spain's dying influence and position in the new world.

Canning's overture was earnestly considered in America. The ex-Presidents, Jefferson and Madison, recommended its acceptance, but the Secretary of State, John Quincy Adams, opposed this, favouring rather a separate declaration by the United States, and of this opinion was also President Monroe. Thus arose the Monroe Doctrine announcing American opposition to the principle of "intervention," and declaring that the American continents were no longer to be regarded as open to further colonization by European nations. The British emergency situation with France, though already quieted, caused Monroe's Message to be greeted in England with high approval. But Canning did not so approve it for he saw clearly that the Monroe Doctrine was a challenge not merely to continental Europe, but to England as well and he set himself to thwart this threatening American policy. Had Canning's policy been followed by later British statesmen there would have resulted a serious clash with the United States[8].

In fact the Monroe Doctrine, imposing on Europe a self-denying policy of non-colonial expansion toward the west, provided
