Treaty of Guadalupe Hidalgo Goes On Tour

Key parts of the historic document that purchased much of the West from Mexico are on display in Tucson during February

The Treaty of Guadalupe Hidalgo defined the U.S. Southwest and, in large part, the international border with Mexico.

When the Treaty was signed on Feb. 2, 1848, Mexico lost about half of its territory to the United States, including present-day California, Arizona, Nevada, Utah, New Mexico, and parts of Colorado, Texas and Wyoming. In exchange for the vast expanse of land, Mexico received $15 million.

Michael Brescia is associate curator of ethnohistory at the Arizona State Museum, and a professor in the history department of the University of Arizona. He says the Treaty of Guadalupe Hidalgo, named for the city in which it was signed, represents an important part of history in the Americas.

Brescia says the document “is a peace treaty that ended hostilities between the United States and Mexico, which means it was a product of war, making it difficult and unsettling to discuss when we are so used to celebrating historical documents and the milieu that created them.”

Brescia points out the U.S./Mexico War stemmed from disputes over Texas, and it was the ensuing clashes between Mexican troops and U.S. forces that provided the rationale for a Congressional declaration of war on May 13, 1846. The president at the time was James Knox Polk.

“Because blood had been shed in that disputed territory,” Brescia says, “President Polk felt he had enough justification to invade Mexico.”

Brescia says the “treaty is a stark reminder that the United States achieved its so-called Manifest Destiny at Mexico’s expense.”

The treaty tells many stories, he points out, “and it’s fair to say that Mexico and Mexicans don’t find much to celebrate in this 1848 document. [Mexicans] are not having parades and setting off fireworks to commemorate the Treaty of Guadalupe Hidalgo.”

The five key articles of the Treaty of Guadalupe Hidalgo are now on display at the Arizona State Museum through the month of February. The complete treaty is housed in the National Archives in Washington, D.C.
