The Treaty of Guadalupe Hidalgo (Tratado de Guadalupe Hidalgo in Spanish) is the peace treaty, largely dictated by the United States^[1][2] to the interim government of a militarily occupied Mexico, that ended the Mexican-American War (1846–1848). The treaty provided for the Mexican Cession, in which Mexico ceded 1.36 million km² (525,000 square miles; 55%^[3] of its pre-war territory, not including Texas) to the United States in exchange for US$15 million (equivalent to $313 million in 2006 dollars) and the ensured safety of pre-existing property rights of Mexican citizens in the transferred territories. Despite assurances to the contrary, property rights of Mexican citizens were often not honored by the United States as per modifications to and interpretations of the treaty.^[4][5][6] The United States also agreed to take over $3.25 million ($68 million in 2006 dollars) in debts Mexico owed to American citizens.

In Mexico, this is sometimes referred to as the War of North American Invasion (La Intervención Norteamericana). Mexico had controlled the area in question for about 25 years since the finalization of its independence from the Spanish Empire in 1821 following the Mexican War of Independence. The Spanish, and later the Mexicans, had conquered part of the area from the Native American tribes over the preceding three centuries, but there remained powerful and independent indigenous peoples within the northern regions.

There were approximately 80,000 Mexicans in the areas of California, New Mexico, Arizona and Texas during this period and they made up about 20% of the population.^[7]

The Treaty took its name from what is now the suburb of Mexico City where it was signed on 2 February 1848.

The cession that the treaty facilitated included parts of the modern-day U.S. states of Colorado, Arizona, New Mexico, and Wyoming, as well as the whole of California, Nevada, and Utah. The remaining parts of what are today the states of Arizona and New Mexico were later peacefully ceded under the 1853 Gadsden Purchase, in which the United States paid an additional $10,000,000.

[edit] Background

On 1 March 1845, United States President John Tyler signed legislation to authorize the United States to annex the Republic of Texas. The annexation occurred on 29 December 1845, and Texas was admitted as the 28th state of the union on the same day. The Mexican government had long warned that annexation meant war with the United States, and had never recognized the Republic of Texas as an independent country. The United Kingdom and France, which both recognized the independence of Texas, repeatedly tried to dissuade Mexico from declaring war against its neighbor. British efforts to mediate were fruitless, in part because additional political disputes (particularly the Oregon boundary dispute) arose between Mexico, Britain and the United States. Before the outbreak of hostilities, on 10 November 1845, U.S. President James K. Polk had sent negotiator John Slidell to Mexico to offer the country around $5 million for the territory of Nuevo México, and up to $40 million for Alta California.^[8] The Mexican government dismissed Slidell, refusing to even meet with him^[9] . Earlier that year Mexico had broken off diplomatic relations with the United States over the annexation of Texas, which Mexico had warned would be considered an act of war if passed by the US Congress. Mexico's basis for this was based partly on an interpretation of the Adams-Onís Treaty of 1819 (which politically independent Mexico had inherited) in which the US had relinquished all claims to Mexican territory, ad infinitum.^[10] Polk, an expansionist, took insult^[9] and did little to prevent war with Mexico.^[11][12] After the Thornton Affair, a skirmish between Mexican and American troops which took place on disputed territory near the Rio Grande (see the Treaties of Velasco), President Polk signed a declaration of war into effect on 13 May 1846, forty-nine days before the Mexican Congress was forced to formally declare war on 1 July.

The war in Mexico's Northern territories largely ended on 13 January 1847, with the signing of the Treaty of Cahuenga. Mexico's subsequent defeat left them with little choice but to accept the United States' demands, or risk total annexation of Mexico.^[9][13] Nicholas Trist, Chief Clerk of the State Department under President Polk, negotiated the treaty with the Mexican delegation, despite having been recalled by the President.^[14] Notwithstanding that the treaty had been negotiated against his instructions, given its favorable terms President Polk passed it on to the Senate.^[14]

[edit] Treaty of Guadalupe Hidalgo

A section of the original treaty

The treaty was signed by Nicholas Trist on behalf of the United States and Luis G. Cuevas, Bernardo Couto and Miguel Atristain as plenipotentiary representatives of Mexico on 2 February 1848, at the main altar of the old Cathedral of Guadalupe at Villa Hidalgo (today Gustavo A. Madero, D.F.), slightly north of Mexico City as U.S troops under the command of General Winfield Scott were occupying Mexico City.

[edit] Changes to the treaty and ratification

The version of the treaty ratified by the United States Senate eliminated Article X^[15], which stated that the U.S. government would honor and guarantee all land grants awarded in lands ceded to the United States to citizens of Spain and Mexico by those respective governments. Article VIII guaranteed that Mexicans who remained more than one year in the ceded lands would automatically become full-fledged American citizens (or they could declare their intention of remaining Mexican citizens); however, the Senate modified Article IX, changing the first paragraph and excluding the last two. Among the changes was that Mexican citizens would "be admitted at the proper time (to be judged of by the Congress of the United States)" instead of "admitted as soon as possible", as negotiated between Trist and the Mexican delegation.

The treaty was subsequently ratified by the United States Senate by a vote of 38 to 14 on 10 March 1848 and by Mexico through a legislative vote of 51 to 34 and a Senate vote of 33 to 4, on 19 May 1848.

[edit] Protocol of Querétaro

On 30 May 1848, when the two countries exchanged ratifications of the treaty of Guadalupe Hidalgo, they further negotiated a three-article protocol to explain the amendments. The first article stated that the original Article IX of the treaty, although replaced by Article III of the Treaty of Louisiana, would still confer the rights delineated in Article IX. The second article confirmed the legitimacy of land grants pursuant to Mexican law.^[16]

The protocol further noted that said explanations had been accepted by the Mexican Minister of Foreign Affairs on behalf of the Mexican Government,^[16] and was signed in Querétaro by A. H. Sevier, Nathan Clifford and Luis de la Rosa.

The United States would later go on to ignore the protocol on the grounds that the U.S. representatives had over-reached their authority in agreeing to it.^[17]

[edit] Treaty of Mesilla

The treaty of Mesilla which concluded the Gadsden purchase of 1854 had significant implications for the treaty of Guadalupe Hidalgo. Article II of the treaty annulled article XI of the treaty of Guadalupe Hidalgo, and article IV further annulled articles VI and VII of Guadalupe Hidalgo. Article V however reaffirmed the property guarantees of Guadalupe Hidalgo, specifically those contained within articles VIII and IX.^[18]

[edit] Effects

The Mexican Cession (red) and the Gadsden Purchase (orange). Part of the area marked as Gadsden Purchase near modern-day Mesilla, New Mexico, was disputed after the Treaty

In addition to the sale of land, the treaty also provided for the recognition of the Rio Grande as the boundary between the State of Texas and Mexico.^[19] The land boundaries were established by a survey team of appointed Mexican and American representatives,^[14] and published in three volumes as The United States and Mexican Boundary Survey. On 30 December 1853, the countries by agreement altered the border from the initial one by increasing the number of border markers from 6 to 53.^[14] Most of these markers were simply piles of stones.^[14] Two later conventions, in 1882 and 1889, further clarified the boundaries, as some of the markers had been moved or destroyed.^[14]

The southern border of California was designated as a line from the junction of the Colorado and Gila rivers westward to the Pacific Ocean, so that it passes one Spanish league south of the southernmost portion of San Diego Bay. This was done to ensure that the United States received San Diego and its excellent natural harbor, without relying on potentially inaccurate designations by latitude.

The treaty extended U.S. citizenship to Mexicans in the newly-purchased territories, long before blacks, Asians and Native Americans were eligible. Between 1850 and 1920, the U.S. Census counted ethnic Mexicans in the white column.^[20]

Community property rights in California are a legacy of the Mexican era. The Treaty of Guadalupe Hidalgo provided that the property rights of Mexican subjects would be kept inviolate. The early Californians felt compelled to continue the community property system regarding the earnings and accumulation of property during a marriage, and it became incorporated into the California constitution.

[edit] Additional issues

Border disputes continued; the United States's desire to expand its territory continued unabated and Mexico's economic problems persisted,^[21] leading to the controversial Gadsden Purchase in 1854 and William Walker's Republic of Lower California filibustering incident in that same year.

The border was routinely crossed by the armed forces of both countries. Mexican and Confederate troops often clashed during the American civil war, and the U.S. is thought to have crossed the border during the war of French intervention in Mexico.

In March 1916, Pancho Villa led a raid on the U.S. border town of Columbus, New Mexico, which was followed by the Pershing expedition.

The shifting of the Rio Grande would much later cause a dispute over the boundary between Purchase lands and those of the state of Texas, called the Country Club Dispute.

Controversy over community land grant claims in New Mexico persist to this day.^[22]

Disputes about whether to make all this new territory into free states or slave-holding states contributed heavily to the rise in North-South tensions that led to the United States Civil War just over a decade later.
