Marblehead Pact (1906)

Marblehead Pact (1906)

On 20 July 1906 official representatives of Guatemala, El Salvador, and Honduras met aboard the U.S.S. Marblehead, anchored off the Guatemalan port of San José. Honorary representatives of Costa Rica and Nicaragua were also present. The United States and Mexico, sponsors of the conference, had brought the isthmian nations together in an effort to resolve the conflict that had erupted between El Salvador and Honduras, on the one hand, and Guatemala on the other. The Marblehead Pact, signed by the three belligerents, called for the ending of hostilities, the release of political prisoners, expanded efforts to control the activities of political émigrés, and a commitment to negotiate, within two months, a general treaty of "peace, amity, and navigation." The conferees designated San José, Costa Rica, as the site for the forthcoming isthmian conference and agreed that in the interim any difficulties involving the signatory powers would be submitted to the arbitration of the presidents of Mexico and the United States.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
