Clayton-Bulwer Treaty

CLAYTON-BULWER TREATY

CLAYTON-BULWER TREATY, a treaty concluded on 19 April 1850 in Washington, D.C., between Secretary of State John Middleton Clayton (1796–1856) and the British minister plenipotentiary, Sir Henry Lytton Bulwer (1801–1872).

Rivalries between the United States and Great Britain had been sharpening in Central America because of British occupation of the Bay Islands (under the sovereignty of Honduras), their establishment of a protectorate over the Mosquito Indians (on the coast of Honduras and Nicaragua), and the seizure of the mouth of the San Juan River (the most probable end of the future canal) in January 1848.

Until the 1850s, the United States had shown a constant but rather mild interest in building a canal; however, since the discovery of gold in California (1848) and the new territorial acquisitions following the Treaty of Guadalupe Hidalgo (1848), it became urgent to secure a shorter and more convenient access to the Pacific coast. This conjunction of commercial, strategic, and security factors led to a growing interest in the Caribbean and Central America, and in British activities there.

The treaty set out that neither Great Britain nor the United States should have exclusive control over the projected canal, nor colonize any part of Central America, but both would guarantee the protection and neutrality of the canal. The treaty was rather speedily ratified by the Senate (42 to 11), but its wording was so ambiguous that it led to a national uproar and became one of the most unpopular in American history.

The treaty was considered as a betrayal of the Monroe Doctrine; the self-denying pledge was an obstacle to the future and inevitable southward expansion of the United States, and the doctrine was devitalized because Britain was permitted to keep what they had illegally seized. Inversely, the treaty was also considered instrumental in strengthening the Monroe Doctrine nationally and internationally, since Britain had implicitly recognized it by accepting not to expand any further in Central America.

Most historians agree that the treaty was a good compromise between a politically, economically, and culturally dominant world power in Latin America—Britain—and a minor though growing-in-influence regional power. Hence the United States probably obtained then as much as it could from Britain. It was not until Theodore Roosevelt's presidency that the United States did obtain the exclusive right to build and fortify the isthmian canal through the Hay-Pauncefote Treaties (1901).

This treaty can be considered both as laying the foundations for the building of the isthmian canal by the United States at the turn of the twentieth century and as consolidating the Caribbean and Central American regions as priorities for American diplomacy and security.

Clayton-Bulwer Treaty

Clayton-Bulwer Treaty, concluded (Apr. 19, 1850) at Washington, D.C., between the United States, represented by Secretary of State John M. Clayton, and Great Britain, represented by the British plenipotentiary Sir Henry Bulwer. American and British rivalries in Central America, particularly over a proposed isthmian canal, led to the treaty. Its most important article provided "that neither … will ever obtain or maintain for itself any exclusive control over the said ship canal … that neither will ever erect or maintain any fortifications commanding the same … or occupy, or fortify, or colonize or assume, or exercise any dominion over Nicaragua, Costa Rica, the Mosquito coast [in present-day Honduras and Nicaragua], or any part of Central America."

Although the treaty was soon ratified by the Senate, it was one of the most unpopular in U.S. history, viewed by some as a betrayal of the Monroe Doctrine. Successive secretaries of state tried in vain to secure modifications that would enable the United States to build its own canal and exercise, under restrictions, political control over it, but it was not until 1901, with the Hay-Pauncefote Treaties, that this end was finally achieved.
