The Pima Revolt , also known as the O'odham Uprising or the Pima Outbreak , was a revolt of Pima native Americans in 1751 against colonial forces in Spanish Arizona and one of the major northern frontier conflicts in early New Spain .
138-448: The revolt culminated from decades of violence by the local Spanish settlers against Indians beginning in 1684. The period was characterized by local Indians' gradual loss of autonomy and territory. Treaties allowing the Spanish to mine and herd on Native lands led to an influx of new settlers; by 1760, Hispanos had become a substantial presence in the present-day American Southwest . However,
276-537: A Mexican element advocating annexation of the entire country to the United States. The majority of congress supported the government's peace policy viewing in the Treaty of Guadalupe nothing but the unfortunate result of a poorly fought war, and viewed under this perspective as a national necessity. A foreign relations commission returned affirmative answers to two questions that congress had directed it to report upon: May
414-473: A far better negotiating position than the military situation might have suggested. A further consideration was the growing opposition to slavery that had caused Mexico to end formal slavery in 1829 and its awareness of the well-known and growing sectional divide in the U.S. over the issue of slavery. It, therefore, made sense for Mexico to negotiate to play Northern U.S. interests against Southern U.S. interests. The Mexicans proposed peace terms that offered only
552-531: A large oasis at the western end of the El Paso-Tucson corridor. The region between the two cities is a major transportation trunk with settlements serving both highway and railway needs. There are also large mining operations, ranches, and agricultural oases. Both El Paso and Tucson have large military installations nearby; Fort Bliss and White Sands Missile Range north of El Paso in New Mexico, and, near Tucson,
690-552: A large part of Chihuahua was supported by both senators from Texas ( Sam Houston and Thomas Jefferson Rusk ), Daniel S. Dickinson of New York, Stephen A. Douglas of Illinois, Edward A. Hannegan of Indiana, and one each from Alabama, Florida, Mississippi, Ohio, Missouri, and Tennessee. Most of the leaders of the Democratic party, Thomas Hart Benton , John C. Calhoun , Herschel V. Johnson , Lewis Cass , James Murray Mason of Virginia and Ambrose Hundley Sevier were opposed, and
828-551: A national guard. On 26 May 1848 the government received the commissioners Nathan Clifford and Ambrose Hundley Sevier who were in Mexico to negotiate the treaty after congress had approved it with some slight modifications. Meanwhile, the President had to deal with guerilla warfare throughout the country afflicting both the American occupiers and Mexican merchants. The aim of the guerillas
966-504: A negotiated peace. When the Pima leaders laid the blame for the revolt on Jesuit missionaries (who would be expelled from Spain and its colonies in 1767), they were pardoned by the colonial governor Ortiz Parrilla. Small scale conflict soon began again, however, and Oacpicagigua eventually died in a Spanish prison in 1755. The colonial government founded three new presidios in Sonora to control
1104-414: A rejection of peace terms so favorable to Northern interests might have the potential to provoke sectional conflict in the United States or perhaps even a civil war that would fatally undermine the U.S. military position in Mexico. Instead, these terms, combined with other Mexican demands (in particular, for various indemnities), only provoked widespread indignation throughout the United States without causing
1242-522: A settlement in Arizona in 1599, but were turned back by inclement weather. In 1610, Santa Fe was founded, making it the oldest capital in United States. In 1664 Juan Archuleta led an expedition into what is now Colorado, becoming the first European to enter. A second Spanish expedition was led into Colorado by Juan Ulibarrí in 1706, during which he claimed the Colorado territory for Spain. From 1687 to 1691
1380-589: A single war plan. The initial act of rebellion was the massacre of 18 settlers lured to Oacpicagigua's home in Sáric on November 20th, 1751. Over the next day, uprisings followed in Caborca , Pitiquito , Oquitoa , Atil , Tubutama , Sonoyta , Busani , Agua Caliente , Baboquivari , Arivaca , and Tubac ; more than a hundred settlers were killed. Oacpicagigua surrendered to Captain José Díaz del Carpio on March 18, 1752 after

This is an area containing the basic elements of Southern history , culture , politics , religion , and linguistic and settlement patterns, yet blended with traits of the frontier West. While this particular Southwest is notably different in many ways from

Texas current borders were set in the Compromise of 1850 , where Texas ceded land to the federal government in exchange for $ 10 million, which would go to paying off the debt Texas had accumulated in its war with Mexico. Following the Mexican Cession, the lands of what had been the Mexican territory of Alta California were in flux: portions of what
1794-402: A treaty with General José Joaquín de Herrera , Trist and General Scott determined that the only way to deal with Mexico was as a conquered enemy. Trist negotiated with a special commission representing the collapsed government led by José Bernardo Couto, Miguel de Atristain, and Luis Gonzaga Cuevas of Mexico. Although Mexico ceded Alta California and Santa Fe de Nuevo México , the text of

It is bounded on the northwest by the Mojave Desert, to the north by the Colorado Plateau and to the east by the Arizona Mountains forests and the Chihuahuan Desert. Aside from the trademark saguaro, the desert has the most diverse plant life of any desert in the world, and includes many other species of cacti, including the organ-pipe, senita, prickly pear, barrel, fishhook, hedgehog, cholla, silver dollar, and jojoba. The portion of

The Mojave gets less than 6 in (150 mm) of rain annually, and its elevation ranges from 3,000 to 6,000 feet (900 to 1,800 meters) above sea level. The most prolific vegetation is the tall Joshua tree , which grow as tall as 40 ft (12 m), and are thought to live almost 1000 years. Other major vegetation includes
2484-573: The American Civil War just over a decade later. Border disputes continued. Mexico's economic problems persisted, leading to the controversial Gadsden Purchase in 1854, intended to rectify an error in the original treaty, but led to Mexico demanding a large sum of money for the revision, which was paid. There was also William Walker 's short-lived Republic of Lower California filibustering incident in that same year. The Channel Islands of California and Farallon Islands are not mentioned in
2622-524: The American Civil War , and the United States crossed the border during the war of Second 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 since the signing of the Treaty of Guadalupe caused a dispute over the boundary between the states of New Mexico and Texas,

Maize began to be cultivated in the region sometime during the early first millennium BC, but it took several hundred years for the native cultures to be dependent on it as a food source. As their dependence on maize grew, Pre-Columbian Indians began developing irrigation systems around 600 CE . According to archeological finds,

Of the states of which at least a portion make up the Southwest, Texas was the first to achieve statehood. On December 29, 1845, the Republic of Texas was annexed, bypassing the status of becoming a territory, and immediately became a state. Initially, its borders included parts of what would become several other states: almost half of New Mexico,
3312-500: The Gadsden Purchase , which was carried out in 1853. In this purchase, the United States paid an additional $ 10 million (equivalent to $ 290 million in 2023) for land intended to accommodate a transcontinental railroad . However, the American Civil War delayed the construction of such a route, and it was not until 1881 that the Southern Pacific Railroad finally was completed as a second transcontinental railroad, fulfilling
3450-608: The Narváez expedition (1528–36) who had crossed eastern Texas on their way to Mexico City, led an expedition to discover the Seven Golden Cities of Cíbola. The 1582–3 expedition of Antonio de Espejo explored New Mexico and eastern Arizona; and this led to Juan de Oñate 's establishment of the Spanish province of Santa Fe de Nuevo México in 1598, with a capital founded near Ohkay Oweenge Pueblo , which he called San Juan de los Caballeros. Oñate's party also attempted to establish

On 10 November 1845, before the outbreak of hostilities, President James K. Polk sent his envoy, John Slidell , to Mexico. Slidell had instructions to offer Mexico around $ 5 million for the territory of Nuevo México and up to $ 40 million for Alta California . The Mexican government dismissed Slidell, refusing to even meet with him. Earlier in that year, Mexico had broken off diplomatic relations with

Both the United Kingdom and France recognized the Republic of Texas's independence and repeatedly tried to dissuade Mexico from declaring war against its northern neighbor. British efforts to mediate the quandary proved fruitless, in part because other political disputes (particularly

As time has gone on, the definition of the Southwest has become more solidified and more compact. For example, in 1948 the National Geographic Society defined the American Southwest as all of California, Nevada, Utah, Arizona, Colorado, and New Mexico, and
4830-473: The 21st century. The United States also agreed to assume $ 3.25 million (equivalent to $ 114.5 million today) in debts that Mexico owed to United States citizens. The residents had one year to choose whether they wanted American or Mexican citizenship; over 90% chose American citizenship. The others moved to what remained of Mexico (where they received land) or, in some cases in New Mexico, were allowed to remain in place as Mexican citizens. Article XII engaged
4968-477: The American Southwest as parts of Arizona, Colorado, Kansas, New Mexico, Oklahoma, Texas, and Utah. From this perspective, almost all of the region's physiographical traits, geological formations, and weather are contained within a box between 26° and 38° northern latitude, and 98° 30' and 124° western longitude. When looking at the fauna of the region, there is a broader definition of the American Southwest. The Southwestern Center for Herpetological Research defines

The area previously occupied by the Mogollon was taken over by an unrelated tribe, the Apache . While it is unclear whether any of the modern Indian tribes are descended from the Mogollon, some archeologists and historians believe that they mixed with Ancestral Puebloans and became part of the modern Hopi and Zuni tribes.

Bordered on the south by the Sonoran Desert and the east by the Colorado Plateau, its range within the region makes up the southeast tip of Nevada, the southwestern corner of Utah and the northwestern corner of Arizona. In terms of topography, the Mojave is very similar to the Great Basin Desert, which lies just to its north. Within the region, Las Vegas is the most populous city; other significant population centers include Laughlin and Pahrump in Nevada, St. George and Hurricane in Utah, and Lake Havasu City , Kingman , and Bullhead City in Arizona.

Just north of the transportation trunk are large blocks of American Indian land. As the US expanded westward , the country's western border also shifted westward, and consequently, so did
7866-448: 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. An amendment by Jefferson Davis giving the United States most of Tamaulipas and Nuevo León , all of Coahuila , and

On August 18, 1846, an American force captured Santa Fe, New Mexico. On December 16 of the same year, American forces captured Tucson, Arizona, marking the end of hostilities in the Southwest United States. When the war ended with the Treaty of Guadalupe Hidalgo on February 2, 1848,

The border commission also faced many difficulties in mapping out the border, with the surveying process lasting over 7 years, due to the challenges of marking out a border in such a vast desolate territory and negotiating with indigenous Americans who had not been considered in the prior treaty negotiations. The armed forces of both countries routinely crossed the border. Mexican and Confederate troops often clashed during

Changing to a common law system for marital property "would have been nothing short of a revolution". The United States received the territories of Alta California and Santa Fe de Nuevo México . Today they comprise some or all of

The land that the Treaty of Guadalupe Hidalgo brought into the United States became, between 1850 and 1912, all or part of nine states: California (1850), Nevada (1864), Utah (1896), and Arizona (1912), as well as, depending upon interpretation,
9522-443: The U.S. government within a year of the Treaty being signed; otherwise, they could remain Mexican citizens, but they would have to relocate. Between 1850 and 1920, the U.S. Census counted most Mexicans as racially "white". Community property rights in California and other western states are based on the Visigothic Code which Spain adopted and then brought to the Americas, including the former territories of Mexico that were ceded to
9660-405: The U.S. states of Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming. While this land was vast in area, most of it was very sparsely populated, inhabited mostly by indigenous Americans, rather than white Americans or Mexicans. Disputes about whether to make all this new territory into free states or slave states contributed heavily to the rise in North–South tensions that led to
9798-446: The United States gained control of all of present-day California, Nevada and Utah, as well as the majority of Arizona, and parts of New Mexico and Colorado (the rest of present-day Colorado, and most of New Mexico had been gained by the United States in their annexation of the Republic of Texas). The final portion of the Southwestern United States came about through the acquisition of the southernmost parts of Arizona and New Mexico through
9936-486: The United States to pay, "In consideration of the extension acquired", 15 million dollars (equivalent to $ 530 million today), in annual installments of 3 million dollars. Article XI of the treaty was important to Mexico. It provided that the United States would prevent and punish raids by Indians into Mexico, prohibited Americans from acquiring property, including livestock, taken by the Indians in those raids, and stated that
10074-486: The United States would return captives of the Indians to Mexico. Mexicans believed that the United States had encouraged and assisted the Comanche and Apache raids that had devastated northern Mexico in the years before the war. This article promised relief to them. Article XI, however, proved unenforceable. Destructive Indian raids continued despite a heavy U.S. presence near the Mexican border. Mexico filed 366 claims with
10212-520: The United States, based partly on its interpretation of the Adams–Onís Treaty of 1819, under which newly independent Mexico claimed it had inherited rights. In that agreement, the United States had "renounced forever" all claims to Spanish territory. Neither side took any further action to avoid a war. Meanwhile, Polk settled a major territorial dispute with Britain via the Oregon Treaty , which

That is to say, the Mexican Cession is construed not to include any territory east of the Rio Grande, while the territorial claims of
10488-526: The United States, would have been presumed by Northerners to be forever free of slavery. The Mexicans also offered to recognize the freedom of Texas from Mexican rule and its right to join the Union but held to its demand of the Nueces River as a boundary. While the Mexican government could not reasonably have expected the Polk Administration to accept such terms, it would have had reason to hope that
10626-559: The acquired territories) failed 15–38 on sectional lines. The treaty was leaked to John Nugent before the U.S. Senate could approve it. Nugent published his article in the New York Herald and, afterward, was questioned by senators. He was detained in a Senate committee room for one month, though he continued to file articles for his newspaper and ate and slept at the home of the sergeant at arms. Nugent did not reveal his source, and senators eventually gave up their efforts. The treaty
10764-507: The amendment was defeated 44–11. An amendment by Whig Sen. George Edmund Badger of North Carolina to exclude New Mexico and California lost 35–15, with three Southern Whigs voting with the Democrats. Daniel Webster was bitter that four New England senators made deciding votes for acquiring the new territories. A motion to insert into the treaty the Wilmot Proviso (banning slavery from
10902-667: The ancestral Puebloans. The modern-day Zuni established a culture along the Zuni River in far-eastern Arizona and western New Mexico. Both major tribes of the O'odham tribe settled in the southern and central Arizona, in the lands once controlled by their ancestors, the Hohokam. The first European intrusion into the region came from the south. In 1539, a Jesuit Franciscan named Marcos de Niza led an expedition from Mexico City which passed through eastern Arizona. The following year Francisco Vázquez de Coronado , based on reports from survivors of
11040-613: The area, namely the Animas , San Andres , and Doña Ana Mountains in New Mexico; and the Franklin , Hueco , and Davis Mountains in Texas. It also reaches up into the foothills of the higher ranges such as the Black Range and Oscura Mountains in New Mexico. High above the desert, these forest-covered and sometimes snow-capped mountains form sky islands , with radically different flora and fauna than
11178-518: The area, while the plateau (which is largely made up of high desert) is the main feature north of the Mogollon Rim . The two major rivers of the region are the Colorado River , running in the northern and western areas, and the Rio Grande , running in the east, north to south. Formed approximately 8000 years ago, the Chihuahuan Desert is a relatively dry desert, although it is slightly wetter than
11316-481: The area. The Chihuahuan Desert is considered the "most biologically diverse desert in the Western Hemisphere and one of the most diverse in the world," and includes more species of cacti than any other desert in the world. The most prolific plants in this region are agave , yucca and creosote bushes , in addition to the ubiquitous presence of various cacti species. When people think of the desert southwest,
11454-567: The arrival of Europeans, the Southwestern United States was inhabited by a very large population of American Indian tribes. The area once occupied by the ancestral Puebloans became inhabited by several American Indian tribes, the most populous of which were the Navajo , Ute , Southern Paiute , and Hopi. The Navajo, along with the Hopi, were the earliest of the modern Indian tribes to develop in
11592-581: The border consisted of the Rio Grande northwest from its mouth to the point where it strikes the southern boundary of New Mexico (roughly 32 degrees north), as shown in the Disturnell map , then due west from this point to the 110th meridian west , then north along the 110th meridian to the Gila River and down the river to its mouth. Unlike the New Mexico segment of the boundary, which depended partly on unknown geography, "to preclude all difficulty in tracing upon
11730-508: The capital. 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
11868-474: The classic "Old South" or Southeast , these features are strong enough to give it a separate southwestern identity quite different in nature from that of the interior southwestern states to the west. Treaty of Guadalupe Hidalgo The Treaty of Guadalupe Hidalgo officially ended the Mexican–American War (1846–1848). It was signed on 2 February 1848 in the town of Guadalupe Hidalgo . After
12006-575: The colonial province of Sonora was characterized by a larger native population, and more frequent conflict between them and the Spaniards. The Pima Indian Revolt was directly preceded by the Seri Revolt of Seri Indians in Sonora. While the Pima people had no central authority, the charismatic Luis Oacpicagigua (Luis of Sáric) began the task of uniting—with varying degrees of success—the disparate groups, numbering at least 15,000 people, under
12144-570: The command of Lt. Colonel John Robert Baylor forced the surrender of the small Union garrison stationed at Fort Fillmore , near Mesilla, New Mexico . On August 1, 1861, Baylor declared the creation of the Arizona Territory , and claimed it for the Confederacy, with Mesilla as its capital. The territory, which had been formed by the portion of the existing New Mexico Territory below the 34th parallel, became official on February 14, 1862. Nevada
12282-485: The defeat of its army and the fall of the capital in September 1847, Mexico entered into peace negotiations with the U.S. envoy, Nicholas Trist . The resulting treaty required Mexico to cede 55 percent of its territory including the present-day states of California , Nevada , Utah , most of Colorado , New Mexico and Arizona , and a small portion of Wyoming . Mexico also relinquished all claims for Texas and recognized
12420-482: The entire state of Texas (1845), which then included part of Kansas (1861); Colorado (1876); Wyoming (1890); Oklahoma (1907); and New Mexico (1912). The area of domain acquired was given by the Federal Interagency Committee as 338,680,960 acres. The cost was $ 16,295,149 or approximately 5 cents an acre. The remainder (the southern parts) of New Mexico and Arizona were peacefully purchased under
12558-530: The establishment of Alta Ski Area , Utah's skiing began to be developed. Due to the ski conditions in the state, during WWII, the 10th Mountain Division established Camp Hale in Colorado to train elite ski troops. While this article deals with the core definition for the American Southwest, there are many others. The various definitions can be broken down into four main categories: Historical/Archeological; Geological/Topographical; Ecological; and Cultural. In
12696-436: The government with the consent of Congress cede a portion of territory? Is it suitable to make peace upon the terms which have been proposed? The first question was resolved based upon the principle that congress was the deposit of the national sovereignty. The second question was resolved upon the consideration that Mexico had never been in full possession of the territories that were about to be ceded, and that most of that land
12834-671: The ground the limit separating Upper from Lower California ", a straight line was drawn from the mouth of the Gila to one marine league south of the southernmost point of the Port of San Diego , slightly north of the previous Mexican provincial boundary at Playas de Rosarito . Comparing the boundary in the Adams–Onís Treaty to the Guadalupe Hidalgo boundary, Mexico conceded about 55% of its pre-war, pre-Texas territorial claims and now has an area of 1,972,550 km (761,610 sq mi). In
12972-595: The heart of the Southwest, called the "Santa Fe Route." It ran from Chicago, down through Topeka, then further south to Albuquerque, before heading almost due west through northern Arizona to Los Angeles. The repeal of the Sherman Silver Purchase Act in 1893 led to the decline of the silver mining industry in the region. In 1901, the Santa Fe Railroad reached the South Rim of the Grand Canyon, opening
13110-428: The historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas , settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities . Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854. While
13248-699: The lands of the central and western portions of northern Arizona. Their village of Oraibi , settled in approximately AD 1100, is, along with Acoma Sky City in New Mexico, one of the oldest continuously occupied settlements in the United States. The Mogollon area became occupied by the Apaches and the Zuni. The Apache migrated into the American Southwest from the northern areas of North America at some point between 1200 and 1500. They settled throughout New Mexico, eastern Arizona, northern Mexico, parts of western Texas, and southern Colorado. The Zuni count their direct ancestry through
13386-413: The landscape of the Sonoran Desert is what mostly comes to mind. The Sonoran Desert makes up the southwestern portion of the Southwest; most of the desert lies in Mexico, but its United States component lies on the southeastern border of California, and the western 2/3 of southern Arizona. Rainfall averages between 4 and 12 in (100 and 300 mm) per year, and the desert's most widely known inhabitant
13524-407: The last of the 48 contiguous United States on February 14, 1912. The 1930s saw the beginning of the ski industry in the Southwest. Resorts were established in Colorado in areas such as Estes Park , Gunnison , and on Loveland Pass . New Mexico's oldest ski area is Sandia Peak Ski Area at the eastern edge of Albuquerque , which opened to skiers in 1936. At the end of the decade, in 1939, with
13662-650: The legitimacy of land grants pursuant to Mexican law. The protocol further noted that the Mexican Minister of Foreign Affairs had accepted said explanations on behalf of the Mexican Government, and was signed in Querétaro by A. H. Sevier, Nathan Clifford and Luis de la Rosa . The United States would later ignore the protocol on the grounds that the U.S. representatives had over-reached their authority in agreeing to it. The Treaty of Mesilla , which concluded
13800-694: The location of the Southwestern and Northwestern United States . In the early years of the United States, newly colonized lands lying immediately west of the Appalachian Mountains were detached from North Carolina and given the name Southwest Territory . During the decades that followed, the region known as "the Southwestern United States" covered much of the Deep South east of the Mississippi River. However, as territories and eventual states to
13938-645: The major US cities in this desert, with other smaller cities being Las Cruces and Roswell in New Mexico and Willcox in Arizona. The elevation in the Chihuahuan varies from about 1,750 to 6,000 feet (500 to 1,800 meters), as there are several larger mountain ranges, such as the Organ Mountains , the Guadalupe Mountains , and the Chiracahua Mountains , plus many smaller mountain ranges contained in
14076-689: The middle of the 15th century AD: the Basketmaker I , II , and III phases followed by the Pueblo I , II , III , and IV . As the Puebloans transitioned from a nomadic lifestyle to one based on both dry land and irrigated agriculture, their first domiciles were pithouses. The Mogollon culture developed later than the Puebloan, arising in the eastern area of the region at around 300 BC. Their range would eventually extend deep into what would become Mexico, and dominate
14214-554: The movement did not draw widespread support. President Polk's State of the Union address in December 1847 upheld Mexican independence and argued at length that occupation and any further military operations in Mexico were aimed at securing a treaty ceding California and New Mexico up to approximately the 32nd parallel north and possibly Baja California and transit rights across the Isthmus of Tehuantepec . Despite several military defeats,
14352-666: The number of border markers from 6 to 53. Most of these markers were simply piles of stones. Two later conventions, in 1882 and 1889, further clarified the boundaries, as some of the markers had been moved or destroyed. Photographers were brought in to document the location of the markers. These photographs are in Record Group 77, Records of the Office of the Chief Engineers, in the National Archives. The southern border of California
14490-526: The purpose of the acquisition. Mexico had claimed the area in question since winning its independence from the Spanish Empire in 1821 following the Mexican War of Independence . The Spanish had conquered part of the area from the American Indian tribes over the preceding three centuries. Still, powerful and independent indigenous nations remained within that northern region of Mexico. Most of that land
14628-554: The region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longitude) to Carlsbad, New Mexico , in the east (104° west longitude); another says that it extends from the Mexico–United States border in the south to the southern areas of Colorado, Utah, and Nevada in the north (39° north latitude). In another definition,
14766-472: The revolt was unsuccessful. In fact, it had the exact opposite effect, for the result of the rebellion was the establishment of the presidio at Tubac , the first permanent European settlement in Arizona. In 1768, the Spanish created the Provincia de las Californias , which included California and the Southwest US. Over approximately the next 50 years, the Spanish continued to explore the Southwest, and in 1776
14904-432: The safety of existing property rights of Mexican citizens living in the transferred territories. Despite assurances to the contrary, land grants by the Mexican government to its citizens were often not honored by the United States because of unilateral modifications to and interpretations of the Treaty and U.S. legal decisions. Land disputes between the descendants of Mexican land owners and Anglo Americans continued into
15042-521: The sale of Alta California north of the 37th parallel north — north of Santa Cruz, California and Madera, California and the southern boundaries of today's Utah and Colorado. Anglo-American settlers already dominated this territory, but perhaps more importantly from the Mexican point of view, it represented the bulk of pre-war Mexican territory north of the Missouri Compromise line of parallel 36°30′ north — lands that, if annexed by
15180-476: The sale of land, the treaty also provided recognition of the Rio Grande as the boundary between the state of Texas and Mexico. The land boundaries were established by a survey team of appointed Mexican and American representatives, 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
15318-467: The sectional conflict the Mexicans hoped for. Jefferson Davis advised Polk that if Mexico appointed commissioners to come to the United States, the government that appointed them would probably be overthrown before they completed their mission, and they would likely be shot as traitors on their return; so that the only hope of peace was to have a U.S. representative in Mexico. Nicholas Trist, chief clerk of
15456-512: The signing of the "Capitulation Agreement" at " Campo de Cahuenga " and the end of the Taos Revolt . By the middle of September 1847, U.S. forces had successfully invaded central Mexico and occupied Mexico City. Some Eastern Democrats called for complete annexation of Mexico and recalled that a group of Mexico's leading citizens had invited General Winfield Scott to become dictator of Mexico after his capture of Mexico City (he declined). However,
15594-402: The sought-after Southwestern architectural styles in the region inspired by blending Pueblo and Territorial styles, with Mediterranean Revival , Spanish Colonial architecture , Mission Revival architecture , Pueblo Deco , and Ranch-style houses in the form of the amalgamated Pueblo Revival and Territorial Revival architectures. This is due to the region's caballero heritage of
15732-460: The south the 37th parallel . In 1862 Nevada's eastern border shifted to the 38th meridian west from Washington , and finally to its current position at the 37th meridian west from Washington in 1866. The boundary modification in 1866 also included adding the southern triangular tip of the present-day state, taken from the Arizona Territory. From July 24–27, 1861 a Confederate force under
15870-402: The southeastern portion of the Southwest. Their settlements would evolve over time from pit-dwellings through pueblos and finally also incorporating cliff-dwellings. The Hohokam were the last of these ancestral cultures to develop, somewhere around AD 1, but they would grow to be the most populous of the three by AD 1300, despite being the smallest of the three in terms of area, covering most of
16008-487: The southernmost sections of Oregon, Idaho, and Wyoming, as well as parts of southwest Nebraska, western Kansas, Oklahoma, and Texas. By 1977, the Society's definition had narrowed to only the four states of Utah, Arizona, Colorado, and New Mexico; and by 1982 the portion of the Southwest in the United States, as defined by the Society, had shrunk to Arizona and New Mexico, with the southernmost strip of Utah and Colorado, as well as
16146-450: The southwest portion. Beginning in approximately AD 600, the Hohokam began to develop an extensive series of irrigation canals; of the three major cultures in the Southwest, only the Ancestral Puebloans of the Chaco culture and the Hohokam developed irrigation as a means of watering their agriculture. Not long after the Hohokam reached the height of their culture, all three major cultures in
16284-591: The surrounding desert below. The sky islands also supply the surrounding desert foothills with flowing water during the spring runoff and after the summer storms of the New Mexican monsoon season . The Chihuahuan is a "rain shadow" desert, formed between two mountain ranges (the Sierra Madre Occidental on the west and the Sierra Madre Oriental on the east) which block oceanic precipitation from reaching
16422-430: The treaty did not list territories to be ceded and avoided the disputed issues that were causes of war: the validity of the 1836 revolution that established the Republic of Texas , Texas's boundary claims as far as the Rio Grande, and the right of the Republic of Texas to arrange the 1845 annexation of Texas by the United States. Instead, Article V of the treaty described the new U.S.–Mexico border . From east to west,
16560-466: The treaty on 10 March and Mexico on 19 May. The ratifications were exchanged on 30 May, and the treaty was proclaimed on 4 July 1848. The U.S. Senate ratified the treaty by a vote of 38–14. The opponents of this treaty were led by the Whigs , who had opposed the war and rejected manifest destiny in general, and rejected this expansion in particular. The amount of land gained by the United States from Mexico
16698-519: The very southern tip of Nevada; while the Utah Territory consisted of Utah, most of Nevada, and portions of Wyoming and Colorado. The New Mexico Territory was expanded along its southern extent, to its current border, with the signing of the Gadsden Purchase Treaty on December 30, 1853, which was ratified by the U.S. Congress, with some slight alterations, in April 1854. The Colorado Territory
16836-474: The very southernmost part of Utah, southwestern Colorado, the very tip of west Texas, and triangle formed by the southern tip of Nevada. This will be the defined scope that is used in this article unless otherwise specified in a particular area. Parts of the other states make up the various areas that can be included in the Southwest, depending on the source. The Learning Center of the American Southwest (LCAS) does not rely on current state boundaries, and defines
16974-448: The way for a tourism boom, a trend led by restaurant and hotel entrepreneur Fred Harvey . The last two territories within the Southwest to achieve statehood were New Mexico and Arizona. By 1863, with the splitting off of the Arizona Territory, New Mexico reached its modern borders. They became states within forty days of one another. On January 6, 1912, New Mexico became the 47th state in the Union. Arizona would shortly follow, becoming
17112-564: The west to Las Vegas, New Mexico in the East. Reed's definition is roughly equivalent to the western half of the Learning Center of the American Southwest's definition, leaving out any portion of Kansas and Oklahoma, and much of Texas, as well as the eastern half of New Mexico. Since this article is about the Southwestern United States, the areas of Sonora and Chihuahua in Mexico will be excluded. The portion left includes Arizona and western New Mexico,
17250-477: The west were added after the Mexican–American War , the geographical "Southwest" expanded, and the relationship of these new acquisitions to the South itself became "increasingly unclear." However, archeologist, Erik Reed, gives a description which is the most widely accepted as defining the American Southwest, which runs from Durango, Colorado in the north, to Durango, Mexico, in the south, and from Las Vegas, Nevada in
17388-506: The westernmost metropolitan areas in the Southwest, while Albuquerque - Santa Fe and El Paso - Las Cruces dominate the easternmost metropolitan areas. Human history in the Southwest begins with the arrival of the Clovis culture , a Paleo-Indian hunter-gatherer culture which arrived sometime around 9000 BC. This culture remained in the area for several millennia. At some point they were replaced by three great Pre-Columbian Indian cultures:
17526-423: Was admitted to the Union on October 31, 1864, becoming the 36th state. This was followed by the admittance to the Union of Colorado, which became the 38th state on August 1, 1876. Confederate Arizona was short-lived, however. By May 1862, Confederate forces had been driven out of the region by union troops. That same month a bill was introduced into the U.S. Congress, and on February 24, 1863 Abraham Lincoln signed
17664-566: 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. The treaty extended the choice of U.S. citizenship to Mexicans in the newly purchased territories before many African Americans, Asians, and Native Americans were eligible. If they chose to, they had to declare to
17802-431: Was either not populated, or populated by hostile indigenous tribes. It was also taken into account that Mexico could not continue the war without facing certain defeat and risking the loss of the entire country. After the commission reported its findings, the Treaty of Guadalupe Hidalgo was approved by congress. President Peña y Peña prepared decrees to prevent disorder in the capital once the occupiers left and to establish
17940-400: Was further increased due to the Gadsden Purchase of 1853, which ceded parts of present-day southern Arizona and New Mexico to the United States. Nicholas Trist negotiated the peace talks; Trist, the chief clerk of the U.S. State Department , accompanied General Winfield Scott as a diplomat and President James K. Polk 's representative. After two previous unsuccessful attempts to negotiate
18078-509: Was occupied, and were now faced with the task of negotiating the treaty while dealing with separatism and anarchy spreading throughout the country. The Caste War was ongoing in Yucatán, and the insurgents in that conflict had occupied the major cities. Many states considered the federal government to be an enemy and refused to pay taxes. Meanwhile, most notably in the Federal District there was
18216-481: Was organized on February 28, 1861, created out of lands then currently in the Utah, Kansas, Nebraska, and New Mexico territories. The Nevada Territory was also organized in 1861, on March 2, with land taken from the existing Utah Territory. Initially, only the western 2/3 of what is currently the State of Nevada was included in the territory, with its boundary to the east being the 39th meridian west from Washington , and to
18354-474: 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 Basilica of Guadalupe at Villa Hidalgo (within the present city limits) as U.S. troops under the command of Gen. Winfield Scott were occupying Mexico City . The version of the treaty ratified by
18492-669: Was signed on 15 June 1846. By avoiding any chance of conflict with Great Britain, the United States was given a free hand regarding Mexico. After the Thornton Affair of 25–26 April, when Mexican forces attacked an American unit in the disputed area, with the result that 11 Americans were killed, five wounded, and 49 captured, Congress passed a declaration of war, which Polk signed on 13 May 1846. The Mexican Congress responded with its own war declaration on 23 April 1846. U.S. forces quickly moved beyond Texas to conquer Alta California, and New Mexico. Fighting there ended on 13 January 1847 with
18630-596: Was subsequently ratified by the U.S. 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. News that New Mexico's legislative assembly had just passed an act for the organization of a U.S. territorial government helped ease Mexican concern about abandoning the people of New Mexico. The treaty was formally proclaimed on 4 July 1848. The Mexican Congress and President Manuel de la Peña y Peña met at Querétaro City in May, 1848 while Mexico City
18768-561: Was to disrupt the American supply chain from Veracruz to the capital. This was also leading to indiscriminate American reprisals. As the peace treaty was concluded and the occupiers were on the point of leaving the country, congress named Jose Joaquin Herrera to the presidency of the republic, and Peña y Peña left his post as president in exchange for the presidency of the Supreme Court on 3 June 1848. The government left Querétaro and returned to
18906-498: Was too dry and too mountainous to support a large population. About 80,000 Mexicans inhabited California, New Mexico, Arizona, and Texas during the period 1845 to 1850, with far fewer in Nevada , southern and western Colorado, and Utah. On 1 March 1845, U.S. President John Tyler signed legislation to authorize the United States to annex the Republic of Texas , effective on 29 December 1845. The Mexican government, which had never recognized
19044-500: Was visited by its first non-Spanish Europeans, English trappers. In 1836, the Republic of Texas , which contained the easternmost of the Southwest United States, won its independence from Mexico. In 1845 the Republic of Texas was annexed by the United States and immediately became a state, bypassing the usual territory phase. The new state still contained portions of what would eventually become parts of other states. In 1846,
