Relations with the Latin American countries south of the Mexican border had been unstable since the Mexican War, an unhappy controversy that left an ineradicable prejudice against us. John Quincy Adams and Henry Clay had hoped for a friendly union of the nations of North and South America, led by the United States, but this ideal had turned out to have no more substance than a vision. Moreover, the increasing trade activity of Great Britain and later of Germany had made a commercial bond of connection between South America and Europe which was, perhaps, stronger than that which the United States had established. Yet some progress was made. Disputes between European governments and the governments of Latin American countries were frequently referred to the United States for arbitration. An old claim of some British subjects, for example, against Colombia was submitted for settlement in 1872 to commissioners of whom the United States minister at Bogota was the most important. The problem was studied with great care and the award was satisfactory to both sides. In 1876 a territorial dispute between Argentina and Paraguay was referred to the President of the United States. In the case of a boundary controversy between Costa Rica and Nicaragua, President Cleveland appointed an arbitrator; Argentina and Brazil presented a similar problem which received the attention of Presidents Harrison and Cleveland. 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
