It fell to James. G. Blaine to revive the idea of a Pan-American conference which had been first conceived by Adams and Clay. As a diplomat, Blaine was possessed of outstanding patriotism and enthusiastic imagination, even if not of vast technical capacity or of an international mind. As Secretary of State under President Garfield in 1881 he invited the Latin American countries to share with the United States in a conference for the discussion of arbitration. The early death of Garfield and the ensuing change in the state department resulted in the abandonment of the project for the time being. Blaine, however, and other interested persons continued to press the plan and in 1888 Congress authorized the President to invite the governments of the Latin American countries to send delegates to a conference to be held in Washington in the following year. By that time President Harrison was in power. Blaine was again Secretary of State and was chosen president of the conference. Among the subjects for discussion were the preservation of peace, the creation of a customs union, uniform systems of weights, measures and coinage, and the promotion of frequent inter-communication among the American states. Little was accomplished, beyond a few recommendations, except the establishment of the International Bureau of American Republics. This was to have no governmental power, but was to be supported by the various nations concerned and was to collect and disseminate information about their laws, products and customs. The Bureau has become permanent under the name Pan American Union and is a factor in the preservation of friendly relations among the American republics. The reciprocity measure which Blaine pressed upon Congress during the pendency of the McKinley tariff bill was designed partly to further Pan-American intercourse.

In the case of a disagreement with Chile, Blaine was less successful. A revolution against the Chilean President, Balmaceda, resulted in the triumph of the insurgents in 1891. The American minister to Chile was Patrick Egan, an Irish agitator who sympathized with President Balmaceda against the revolutionists and who was persona non grata to the strong English and German colonies there. While Chilean affairs were in this strained condition, the revolutionists sent a vessel, the Itata, to San Diego in California for military supplies, and American authorities seized it for violating the neutrality laws. While the vessel was in the hands of our officers, the Chileans took control of it and made their escape. The cruiser Charleston was sent in pursuit and thereupon the revolutionists surrendered the Itata. Not long afterward, however, a United States Court decided that the pursuit had been without justification under international law and ordered the release of the Itata. The result was that the United States seemed to have been over-ready to take sides against the revolutionists, and the latter became increasingly hostile to Americans.

Relations finally broke under the strain of a street quarrel in the city of Valparaiso in the fall of 1891. A number of sailors from the United States ship Baltimore were on shore leave and fell in with some Chilean sailors in a saloon. A quarrel resulted—just how it originated and just who was the aggressor could not be determined—but at any rate the Americans were outnumbered and one was killed. The administration pressed the case with vigor, declining to look upon the incident as a sailors' brawl and considering it a hostile attack upon the wearers of an American uniform. For a time the outbreak of war was considered likely, but eventually Chile yielded, apologized for its acts and made a financial return for the victims of the riot. Later students of Chilean relations have not praised Egan as minister or Blaine's conduct of the negotiations, but it is fair to note that the Chileans were prejudiced against the American Secretary of State because of an earlier controversy in which he had sided against them, and that the affair was complicated by the presence of powerful European colonies and by the passions which the revolution had aroused.

Blaine was compelled to face another embarrassing situation in dealing with Italy in 1891-1892. In October, 1890, the chief of police of New Orleans, D.C. Hennessy, had been murdered and circumstances indicated that the deed had been committed by members of an Italian secret society called the Mafia. A number of Italians were arrested, of whom three were acquitted, five were held for trial and three were to be tried a second time. One morning a mob of citizens, believing that there had been a miscarriage of justice, seized the eleven and killed all of them. The Italian government immediately demanded protection for Italians in New Orleans, as well as punishment of the persons concerned in the attack, and later somewhat impatiently demanded federal assurance that the guilty parties would be brought to trial and an acknowledgment that an indemnity was due to the relatives of the victims of the mob. Failing to obtain these guarantees, the Italian government withdrew its minister. When a grand jury in New Orleans investigated the affair it excused the participants and none of them was brought to trial.

The government at Washington was hampered by the fact that judicial action in such a case lies with the individual state under our form of government, whereas diplomatic action is of course entirely federal. If the states are tardy or derelict in action, the national government is almost helpless. President Harrison urged Congress to make offenses against the treaty rights of foreigners cognizable in the federal courts, but this was never done. Diplomatic activity, however, brought better results, and an expression of regret on the part of the United States, together with the payment of an indemnity of $24,000 closed the incident.

Among the many troublesome questions that faced President Cleveland when he entered upon the Presidency in 1893 for the second time, the status of the Hawaiian Islands was important. Since the development of the Pacific Coast of the United States in the forties and fifties, there had been a growing trade between the islands and this country. Reciprocity and even annexation had been projected. In 1875 a reciprocity arrangement was consummated, a part of which was a stipulation that none of the territory of Hawaii should be leased or disposed of to any other power. In this way a suggestion was made of ultimate annexation. Moreover the commercial results of the treaty were such as to make a friendly connection with the United States a matter of moment to Hawaii. The value of Hawaiian exports had increased, government revenues enlarged, and many public improvements had been made. In 1884 the grant of Pearl Harbor to the United States as a naval station made still another bond of connection between the islands and their big neighbor.

The King of Hawaii during this period of prosperity was Kalakaua. During a visit to the United States, and later during a tour of the world he was royally received, whereupon he returned to his island kingdom with expanded theories of the position which a king should occupy. Unhappily he dwelt more on the pleasures which a king might enjoy than upon the obligations of a ruler to his people. At his death in 1891 Princess Liliuokalani became Queen and at once gave evidence of a disposition to rule autocratically. Because of her attempts to revise the Hawaiian system of government so as to increase the power of the crown, the more influential citizens assembled, appointed a committee of public safety and organized for resistance. On January 17, 1893, the revolutionary elements gathered, proclaimed the end of the monarchical regime and established a provisional government under the leadership of Judge S.B. Dole. The new authorities immediately proposed annexation to the United States and a treaty was promptly drawn up in accord with President Harrison's wishes, and presented to the Senate. At this point the Harrison administration ended and Cleveland became President.

Cleveland immediately withdrew the treaty for examination and sent James H. Blount to the islands to investigate the relation of American officials to the recent revolution. The appointment of Blount was made without the advice and consent of the Senate and was denounced by the President's enemies, although such special missions have been more or less common since the beginning of our history.[7] Blount reported that the United States minister to Hawaii, J.L. Stevens, had for some time been favorably disposed to a revolution in the islands and had written almost a year before that event asking how far he and the naval commander might deviate from established international rules in the contingency of a rebellion. "The Hawaiian pear is now fully ripe," Stevens had written to the State Department, early in 1893, "and this is the golden hour for the United States to pluck it." Blount also informed the President that the monarchy had been overturned with the active aid of Stevens and through the intimidation caused by the presence of an armed naval force of the United States.

The blunt language which Cleveland employed in his message to Congress on the subject, left no doubt about his opinion of the transaction. "The control of both sides of a bargain acquired in such a manner is called by a familiar and unpleasant name when found in private transactions." Believing that an injustice had been done and that the only honorable course was to undo the wrong, he sent A.S. Willis as successor to Stevens to express the President's regret and to attempt to make amends. One of the conditions however which President Cleveland placed upon the restoration of the Queen was a promise of amnesty to all who had shared in the revolution. The Queen was at first unwilling to bind herself and when she later agreed, a new obstacle appeared in the refusal of the provisional government to surrender its authority. Indeed it began to appear that the President's sense of justice was forcing him to attempt the impossible. The provisional government had already been recognized by the United States and by other powers, the deposition of the Queen was a fait accompli and her restoration partook of the nature of turning back the clock. Moreover, force would have to be used to supplant the revolutionary authorities,—a task for which Americans had no desire. The President, in fact, had exhausted his powers and now referred the whole affair to Congress. The House condemned Stevens for assisting in the overturn of the monarchy and went on record as opposed to either annexation or an American protectorate. Sentiment was less nearly uniform in the upper chamber. The Democrats tended to uphold the President, the Republicans to condemn him. Although a majority of the committee on foreign relations exonerated Stevens, yet no opposition appeared to a declaration which passed the Senate on May 31, 1894, maintaining that the United States ought not to intervene in Hawaiian affairs and that interference by any other government would be regarded as unfriendly to this country.

In the outcome, these events merely delayed annexation; they could not prevent it. In Hawaii the more influential and the propertied classes supported the revolution and desired annexation. In the United States the desire for expansion was stimulated by the fear that some other nation might seize the prize. The military and naval situation in 1898 increased the demand for annexation, and in the summer of that year the acquisition was completed by means of a joint resolution of the two houses of Congress.[8] While negotiations were in progress Japan protested that her interests in the Pacific were endangered. Assurances were given, however, that Japanese treaty rights would not be affected by the annexation and the protest was withdrawn. The United States was now "half-way across to Asia."
