Desire for a southern transcontinental rail line

As the railroad age evolved, business-oriented Southerners saw that a railroad linking the South with the Pacific Coast would expand trade opportunities. They thought the topography of the southern portion of the original boundary line was too mountainous to allow a direct route. Projected southern railroad routes tended to veer to the north as they proceeded eastward, which would favor connections with northern railroads and ultimately favor northern seaports. Southerners saw that to avoid the mountains, a route with a southeastern terminus might need to swing south into what was still Mexican territory. The administration of President Pierce, strongly influenced by Secretary of War Jefferson Davis, saw an opportunity to acquire land for the railroad, as well as to acquire significant other territory from northern Mexico. In those years, the debate over slavery in the United States entered into many other debates, as the acquisition of new territory opened the question of whether it would be slave or free territory; in this case, the debate over slavery ended progress on construction of a southern transcontinental rail line until the early 1880s, although the preferred land became part of the nation and was used as intended after the Civil War.

In addition, many Southern business interests feared that a northern transcontinental route would exclude the South from trade with the Orient. Other Southerners argued for diversification from a plantation economy to keep the South independent of northern bankers. In October 1849, the southern interests held a convention to discuss railroads in Memphis, in response to a convention in St. Louis earlier that fall which discussed a northern route. The Memphis convention overwhelmingly advocated the construction of a route beginning there, to connect with an El Paso, Texas to San Diego, California line. Disagreement arose only over the issue of financing. The convention president, Matthew Fontaine Maury of

was admitted to the Union as a free state in 1850, he advocated secession by South Carolina. Gadsden considered slavery "a social blessing" and abolitionists "the greatest curse of the nation". When the secession proposal failed, Gadsden worked with his cousin Isaac Edward Holmes, a lawyer in San Francisco since 1851, and California state senator Thomas Jefferson Green, in an attempt to divide California into northern and southern portions and proposed that the southern part allow slavery. Gadsden planned to establish a slave-holding colony there based on rice, cotton, and sugar, and wanted to use slave labor to build a railroad and highway that originated in either

or the Red River valley. The railway or highway would transport people to the California gold fields. Toward this end, on December 31, 1851, Gadsden asked Green to secure from the California state legislature a large land grant located between the 34th and 36th parallels, along the proposed dividing line for the two California states. A few months later, Gadsden and 1,200 potential settlers from South Carolina and

railroad to be financed by "federal land grants for the specific purpose of railroad construction". To satisfy Southern opposition to the general principle of federally supported internal improvements, the land grants would first be transferred to the appropriate state or territorial government, which would oversee the final transfer to private developers. By 1850, however, the majority of the South was not interested in exploiting its advantages in developing a transcontinental railroad or railroads in general. Businessmen like Gadsden, who advocated economic diversification, were in the minority. The Southern economy was based on cotton exports, and then-current transportation networks met the plantation system's needs. There was little home market for an intra-South trade. In the short term, the best use for capital was to invest it in more slaves and land rather than in taxing it to support canals, railroads, roads, or in dredging rivers. Historian Jere W. Roberson wrote:


Treaty of Guadalupe Hidalgo

The Treaty of Guadalupe Hidalgo (1848) ended the Mexican–American War, but left issues affecting both sides that still needed to be resolved: possession of the Mesilla Valley, protection for Mexico from Indian raids, and the right of transit in the Isthmus of Tehuantepec.


Mesilla Valley

The treaty provided for a joint commission, made up of a surveyor and commissioner from each country, to determine the final boundary between the United States and Mexico. The treaty specified that the Rio Grande Boundary would veer west eight miles (13 km) north of El Paso. The treaty was based on the attached 1847 copy of a twenty-five-year-old map. Surveys revealed that El Paso was further south and further west than the map showed. Mexico favored the map, but the United States put faith in the results of the survey. The disputed territory involved a few thousand square miles and about 3,000 residents; more significantly, it included the Mesilla Valley. Bordering the Rio Grande, the valley consisted of flat desert land measuring about , north to south, by , east to west. This valley was essential for the construction of a transcontinental railroad using a southern route. John Bartlett of

estimated that five times that amount would be necessary to police the border. Mexican officials, frustrated with the failure of the United States to effectively enforce its guarantee, demanded reparations for the losses inflicted on Mexican citizens by the raids. The United States argued that the Treaty did not require any compensation nor did it require any greater effort to protect Mexicans than was expended in protecting its own citizens. During the Fillmore administration, Mexico claimed damages of $40 million (equivalent to $ in ) but offered to allow the U.S. to buy-out Article XI for $25 million ($) while President Fillmore proposed a settlement that was $10 million less ($).


Isthmus of Tehuantepec

During negotiations of the treaty, Americans had failed to secure the right of transit across the Isthmus of Tehuantepec in southern Mexico. The idea of building a railroad here had been considered for a long time, connecting the Gulf of Mexico with the Pacific Ocean. In 1842 Mexican President Antonio López de Santa Anna sold the rights to build a railroad or canal across the isthmus. The deal included land grants wide along the right-of-way for future colonization and development. In 1847 a British bank bought the rights, raising U.S. fears of British colonization in the hemisphere, in violation of the precepts of the Monroe Doctrine. United States interest in the right-of-way increased in 1848 after the gold strikes in the Sierra Nevada, which led to the California Gold Rush.; . The Memphis commercial convention of 1849 recommended that the United States pursue the trans-isthmus route, since it appeared unlikely that a transcontinental railroad would be built anytime soon. Interests in Louisiana were especially adamant about this option, as they believed that any transcontinental railroad would divert commercial traffic away from the Mississippi and New Orleans, and they at least wanted to secure a southern route. Also showing interest was Peter A. Hargous of New York who ran an import-export business between New York and

Mexican negotiators refused the treaty because it would eliminate Mexico's ability to play the US and Britain against each other. They eliminated the right of the United States to unilaterally intervene militarily. The United States Senate approved the treaty in early 1851, but the Mexican Congress refused to accept the treaty.. In the meantime, Hargous proceeded as if the treaty would be approved eventually. Judah P. Benjamin and a committee of New Orleans businessmen joined with Hargous and secured a charter from the Louisiana legislature to create the Tehuantepec Railroad Company. The new company sold stock and sent survey teams to Mexico. Hargous started to acquire land even after the Mexican legislature rejected the treaty, a move that led to the Mexicans canceling Hargous' contract to use the right of way. Hargous put his losses at $5 million (equivalent to $ in ) and asked the United States government to intervene. President Fillmore refused to do so. Mexico sold the canal franchise, without the land grants, to A. G. Sloo and Associates in New York for $600,000 (equivalent to $ in ). In March 1853 Sloo contracted with a British company to build a railroad and sought an exclusive contract from the new Franklin Pierce Administration to deliver mail from New York to San Francisco. However, Sloo soon defaulted on bank loans and the contract was sold back to Hargous.


Final negotiations and ratification of the treaty of purchase

. Pierce's Secretary of War, Jefferson Davis, was already on record as favoring a southern route for a transcontinental railroad, so southern rail enthusiasts had every reason to be encouraged. The South as a whole, however, remained divided. In January 1853, Senator Thomas Jefferson Rusk of Texas introduced a bill to create two railroads, one with a northern route, and one with a southern route starting below Memphis on the Mississippi River. Under the Rusk legislation, the President would be authorized to select the specific termini and routes as well as the contractors who would build the railroads. Some southerners, however, worried that northern and central interests would leap ahead in construction and opposed any direct aid to private developers on constitutional grounds. Other southerners preferred the isthmian proposals. An amendment was added to the Rusk bill to prohibit direct aid, but southerners still split their vote in Congress and the amendment failed. This rejection led to legislative demands, sponsored by William Gwin of California and

Gadsden and Santa Anna

A treaty initiated in the Fillmore administration that would provide joint Mexican and United States protection for the Sloo grant was signed in Mexico on on March 21, 1853. At the same time that this treaty was received in Washington, Pierce learned that New Mexico Territorial Governor
William C. Lane William Carr Lane (December 1, 1789January 6, 1863) was a doctor and the first mayor of St. Louis, Missouri, serving from 1823 to 1829 and 1837 to 1840. He later served as Governor of New Mexico Territory, from 1852 to 1853. Born in Faye ...

. Pierce recalled Lane in May and replaced him with David Meriwether of Kentucky. Meriwether was given orders to stay out of the Mesilla Valley until negotiations with Mexico could be completed. With the encouragement of Davis, Pierce also appointed James Gadsden as ambassador to Mexico, with specific instructions to negotiate with Mexico over the acquisition of additional territory. Secretary of State William L. Marcy gave Gadsden clear instructions: he was to secure the Mesilla Valley for the purposes of building a railroad through it, convince Mexico that the US had done its best regarding the Indian raids, and elicit Mexican cooperation in efforts by US citizens to build a canal or railroad across the Isthmus of Tehuantepec. Supporting the Sloo interests was not part of the instructions. Gadsden met with Santa Anna in Mexico City on September 25, 1853, to discuss the terms of the treaty. The Mexican government was going through political and financial turmoil. In the process, Santa Anna had been returned to power about the same time that Pierce was inaugurated. Santa Anna was willing to deal with the United States because he needed money to rebuild the Mexican Army for defense against the United States. He initially rejected the extension of the border further south to the Sierra Madre Mountains. He initially insisted on reparations for the damages caused by American Indian raids, but agreed to let an international tribunal resolve this. Gadsden realized that Santa Anna needed money and passed this information along to Secretary Marcy.. Marcy and Pierce responded with new instructions. Gadsden was authorized to purchase any of six parcels of land with a price fixed for each. The price would include the settlement of all Indian damages and relieve the United States from any further obligation to protect Mexicans. $50 million (equivalent to $ in ) would have bought the Baja California Peninsula and a large portion of its northwestern Mexican states while $15 million ($) was to buy the of desert necessary for the railroad plans. "Gadsden's antagonistic manner" alienated Santa Anna. Gadsden had advised Santa Anna that "the spirit of the age" would soon lead the northern Mexican states to secede so he might as well sell them now. Mexico balked at any large-scale sale of territory. The Mexican President felt threatened by

with 50 troops and annex Sonora. Gadsden disavowed any government backing of Walker, who retreated to the U.S. and was placed on trial as a criminal.. Santa Anna worried that the US would allow further aggression against Mexican territory. Santa Anna needed to get as much money for as little territory as possible. When the United Kingdom rejected Mexican requests to assist in the negotiations, Santa Anna opted for the $15 million package (equivalent to $ in ).. Santa Anna signed the treaty on December 30, 1853, along with James Gadsden. Then the treaty was presented to the U.S. Senate for confirmation.


Ratification

Pierce and his cabinet began debating the treaty in January 1854. Although disappointed in the amount of territory secured and some of the terms, Pierce signed it, and submitted it to the Senate on February 10. Gadsden, however, suggested that northern Senators would block the treaty to deny the South a railroad. The treaty needed a two-thirds vote in favor of ratification in the US Senate, where it met strong opposition. Anti-slavery senators opposed further acquisition of slave territory. Lobbying by speculators gave the treaty a bad reputation. Some Senators objected to furnishing Santa Anna financial assistance. The treaty reached the Senate as that body focused on the debate over the Kansas–Nebraska Act. On April 17, after much debate, the Senate voted 27 to 18 in favor of the treaty, falling three votes short of the necessary two-thirds majority. After this defeat, Secretary Davis and southern Senators pressed Pierce to add more provisions to the treaty including: * protection for the Sloo grant; * a requirement that Mexico "protect with its whole power the prosecution, preservation, and security of the work eferring to the isthmian canal; * permission for the United States to intervene unilaterally "when it may feel sanctioned and warranted by the public or international law"; and * a reduction of the territory to be acquired by to the final size of , and dropping the price to $10 million (equivalent to $ in ) from $15 million ($). The land area included in the treaty is shown in the map at the head of the article, and in the national map in this section. This version of the treaty successfully passed the US Senate April 25, 1854, by a vote of 33 to 12. The reduction in territory was an accommodation of northern senators who opposed the acquisition of additional slave territory. In the final vote, northerners split 12 to 12. Gadsden took the revised treaty back to Santa Anna, who accepted the changes. The treaty went into effect June 30, 1854. While the land was available for construction of a southern railroad, the issue had become too strongly associated with the sectional debate over slavery to receive federal funding. Roberson wrote:. The effect was such that railroad development, which accelerated in the North, stagnated in the South..

. The Mexican people opposed such boundaries, as did anti-slavery Americans, who saw the purchase as acquisition of more slave territory. Even the sale of a relatively small strip of land angered the Mexican people, who saw Santa Anna's actions as a betrayal of their country. They watched in dismay as he squandered the funds generated by the Purchase. Contemporary Mexican historians continue to view the deal negatively and believe that it has defined the American–Mexican relationship in a deleterious way. The purchased lands were initially appended to the existing New Mexico Territory. To help control the new land, the

The difficulty of governing the new areas from the territorial capital at Santa Fe led to efforts as early as 1856 to organize a new territory out of the southern portion. Many of the early settlers in the region were, however, pro-slavery and sympathetic to the South, resulting in an impasse in Congress as to how best to reorganize the territory.

would cause a later dispute over the boundary between Purchase lands and those of the state of Texas, known as the Country Club Dispute. Pursuant to the Treaty of Guadalupe Hidalgo, the Gadsden Treaty and subsequent treaties, the International Boundary and Water Commission was established in 1889 to maintain the border. Pursuant to still later treaties, the IBWC expanded its duties to allocation of river waters between the two nations, and provided for flood control and water sanitation. Once viewed as a model of international cooperation, in recent decades the IBWC has been heavily criticized as an institutional anachronism, by-passed by modern social, environmental, and political issues.


Growth of the region after 1854


Army control

The residents of the area gained full US citizenship and slowly assimilated into American life over the next half-century. The principal threat to the peace and security of settlers and travelers in the area was raids by Apache Indians. The US Army took control of the purchase lands in 1854 but not until 1856 were troops stationed in the troubled region. In June 1857 it established Fort Buchanan south of the Gila at the head of the Sonoita Creek Valley. The fort protected the area until it was evacuated and destroyed in July 1861. The new stability brought miners and ranchers. By the late 1850s mining camps and military posts had not only transformed the Arizona countryside; they had also generated new trade linkages to the state of Sonora, Mexico. Magdalena, Sonora, became a supply center for Tubac; wheat from nearby Cucurpe fed the troops at Fort Buchanan; and the town of Santa Cruz sustained the Mowry mines, just miles to the north.


Civil War

American Civil War The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by state ...

formed the Confederate Territory of Arizona, including in the new territory mainly areas acquired by the Gadsden Purchase. In 1863, using a north-to-south dividing line, the Union created its own Arizona Territory out of the western half of the New Mexico Territory. The new American Arizona Territory also included most of the lands acquired in the Gadsden Purchase. This territory would be admitted into the Union as the State of Arizona on February 14, 1912, the last area of the Lower 48 States to receive statehood.


Social development

After the Gadsden Purchase, southern Arizona's social elite, including the Estevan Ochoa, Mariano Samaniego, and Leopoldo Carillo families, remained primarily Mexican American until the coming of the railroad in the 1880s. When the Sonora Exploring and Mining Company opened silver mines in southern Arizona, it sought to employ educated, middle-class Americans who shared a work ethic and leadership abilities to operate the mines. A biographical analysis of some 200 of its employees, classed as capitalists, managers, laborers, and general service personnel, reveals that the resulting work force included Europeans, Americans, Mexicans, and Indians. This mixture failed to stabilize the remote area, which lacked formal social, political, and economic organization in the years from the Gadsden Purchase to the Civil War.


Economic development

From the late 1840s into the 1870s, Texas stockmen drove their beef cattle through southern Arizona on the Texas–California trail. Texans were impressed with the grazing possibilities offered by the Gadsden Purchase country of Arizona. In the last third of the century, they moved their herds into Arizona and established the range cattle industry there. The Texans contributed their proven range methods to the new grass country of Arizona, but also brought their problems as well. Texas rustlers brought lawlessness, poor management resulted in overstocking, and carelessness introduced destructive diseases. But these difficulties did force laws and associations in Arizona to curb and resolve them. The Anglo-American cattleman frontier in Arizona was an extension of the Texas experience. When the Arizona Territory was formed in 1863 from the southern portion of the New Mexico Territory, Pima County and later Cochise County—created from the easternmost portion of Pima County in January 1881—were subject to ongoing border-related conflicts. The area was characterized by rapidly growing boom towns, ongoing Apache raids, smuggling and cattle rustling across the United States-Mexico border, growing ranching operations, and the expansion of new technologies in mining, railroading, and telecommunications. In the 1860s conflict between the Apaches and the Americans was at its height. Until 1886, almost constant warfare existed in the region adjacent to the Mexican border. The illegal cattle operations kept beef prices in the border region lower and provided cheap stock that helped small ranchers get by. Many early Tombstone, Arizona residents looked the other way when it was "only Mexicans" being robbed. Outlaws derisively called " The Cowboys" frequently robbed

In the 1870s and 1880s there was considerable tension in the region—between the rural residents, who were for the most part Democrats from the agricultural South, and town residents and business owners, who were largely

from the industrial Northeast and Midwest. The tension culminated in what has been called the Cochise County feud, and the Earp-Clanton feud, which ended with the historic Gunfight at the O.K. Corral and Wyatt Earp's Vendetta Ride. The Gadsden purchase resulted in the division of the Tohono Oʼodham Nation and its ancestral lands by the new international border. This disrupted traditional migratory practices and transportation of materials and goods essential for their spirituality, economy and traditional culture. Nine communities are on the Mexican side of this boundary. Conflicts have arisen mainly in the 21st century with stronger enforcement of customs laws at the border.


Railroad development

In 1846, James Gadsden, then president of the South Carolina Railroad, proposed building a transcontinental railroad linking the Atlantic at Charleston with the Pacific at San Diego. Federal and private surveys by Lt. John G. Parke and Andrew B Gray proved the feasibility of the southern transcontinental route, but sectional strife and the Civil War delayed construction of the proposed railroad. The

in March 1880, Deming, New Mexico in December 1880, and El Paso in May 1881, the first railroad across the Gadsden Purchase. At the same time, 1879–1881, the Atchison, Topeka and Santa Fe Railroad was building across New Mexico and met the Southern Pacific at Deming, New Mexico March 7, 1881, completing the second transcontinental railroad (the first, the central transcontinental, was completed May 10, 1869 at Promontory Summit, Utah). Acquiring trackage rights over the SP, from Deming to Benson, the Santa Fe then built a line southwest to Guaymas, Sonora, Mexico, completed October 1882, as its first outlet to the Pacific. This line was later sold to the Southern Pacific. The Southern Pacific continued building east from El Paso, completing a junction with the Texas & Pacific in December 1881, and finally in 1883, its own southern transcontinental, the Sunset Route, California to New Orleans, Atlantic waters to the Pacific. These railroads caused an early 1880s mining boom in such locales as Tombstone, Arizona, Bisbee, Arizona, and Santa Rita, New Mexico, the latter two world class copper producers. From Bisbee, a third sub-transcontinental was built across the Gadsden Purchase, the El Paso and Southwestern Railroad, to El Paso by 1905, then to a link with the Rock Island line to form the Golden State Route. The EP&SW was sold to the Southern Pacific in the early 1920s. The portion of the Southern Pacific in Arizona was originally largely in the Gadsden Purchase but the western part was later rerouted north of the Gila River to serve the city of Phoenix (as part of the agreement in purchasing the EP&SW). The portion in New Mexico runs largely through the territory that had been disputed between Mexico and the United States after the Treaty of Guadalupe Hidalgo had gone into effect, and before the time of the Gadsden Purchase.

) and the Santa Fe (now part of the BNSF), are among the busiest rail lines in the United States.

Most of these railroads have been abandoned. The remainder of the Gila Valley pre-Purchase border area was traversed by the Arizona Eastern Railway by 1899 and the

This highway is well north of the Gadsden Purchase. Given the elevations of those three places, at least a 3% grade would have been required for rails built here, rather than the final alignment; railroads prefer 1% or less grade for better operation. This rugged terrain above the Gila River confirms the engineering, technical wisdom of acquiring the Gadsden Purchase for a southern transcontinental railroad. To William H. Emory of the U. S. Army Corps of Topographical Engineers who surveyed the region in the 1840s–1850s, it was a good route "to the Pacific."


Population


Arizona

The boundaries of most counties in Arizona do not follow the northern boundary of the Gadsden Purchase, but six counties in Arizona do have most of their populations within the land of the Gadsden Purchase. Four of these also contain areas north of the Gadsden Purchase, but these areas have low population densities, with the exception of northeastern Pinal County including the towns of Apache Junction and

Cost effectiveness

Geologist Harold L. James stated in 1969 about the Gadsden Purchase: "Although the boundary controversy did not teach any lessons or impart any wisdom, it did lead to the purchase of an extremely valuable strip of territory that has more than paid for itself in subsequent mineral and agricultural resources. Despite the comedy of errors, chaos, and misunderstanding, the Southwest must therefore be grateful." However, economist David R. Barker estimated in 2009 that the purchase was likely not profitable for the United States federal government. Stating that "Current historical accounts take it for granted that the purchase has been a boon to the United States", he calculated that the region produces little tax revenue; most mines are on Indian reservations which receive all royalties. The federal government spent a great deal of money during the 19th century to defend the territory from Apaches that would not have been necessary without the purchase.


In popular culture

The consequences of the Gadsden Purchase for Mexicans and Native Americans living in the region form the background of the story in the film '' Conquest of Cochise'' (Columbia, 1953). The United States Post Office Department issued a postage stamp commemorating 100 years since the Gadsden Purchase, on December 30, 1953. In 2012, the Gadsden Purchase was featured in a segment on '' Late Night with Jimmy Fallon''.Archived a
