May Pacts (1902)

May Pacts (1902)

The Pactos de Mayo were a series of four diplomatic treaties between Chile and Argentina negotiated in 1902. Since the mid-nineteenth century, Buenos Aires and Santiago had disputed the location of their common border. The arguments became so hostile that both nations began modernizing their armies as well as engaging in a costly naval arms race in preparation for war. Great Britain convinced the two countries to negotiate a settlement, which resulted in the Pactos de Mayo.

The treaties achieved several goals: they established a mechanism for the peaceful settlement of the outstanding boundary issues and ended the naval competition by setting a rough parity between the two nations' fleets. More significantly, each country recognized the other's hegemony on its own coasts: Argentina promised not to intervene in the Pacific basin, and Chile respected Argentina's domination of the Atlantic. Thus, the treaties not only provided a mechanism for resolving their long-festering border dispute, they also recognized the rights of the signatories in their respective spheres of influence, thereby avoiding future possible irritants to international peace.

Citation styles

Encyclopedia.com 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, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com 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:
