Gadsden Purchase

Wikipedia, the free encyclopedia - Cite This Source

The Gadsden Purchase (known as Venta de La Mesilla in Mexico) is a region of what is today southern Arizona and New Mexico that was purchased by the United States from Mexico in 1853 for $10 million. The initial purchase treaty was signed in Mexico in 1853, but a very different treaty was finally ratified by the U.S. Senate and signed by President Franklin Pierce on June 24, 1854. The purchase included lands south of the Gila River and west of the Rio Grande.

Purpose

The Gadsden Purchase was intended to allow for the construction of a southern route for a transcontinental railroad. On December 30 1853, U.S. Minister to Mexico James Gadsden and Mexican President Antonio Lopez de Santa Anna agreed on the price of $10 million for the Gadsden land, which valued the included territory at around $340 per square mile ($130/km²) or about 53 cents per acre.

As the railroad age blossomed, many southerners wanted to build, or at least provide a route for, a southern transcontinental railroad, linking the South with the Pacific coast and providing expanded trade opportunities (and possibly expansion of slave territory). However, the topography of the southern portion of the Mexican Cession was too mountainous to allow a direct route, and what possible routes existed tended to run to the north at their eastern ends, which would favor connections with northern railroads. Interested southerners tended to prefer New Orleans as the eastern terminus of the southern route, but to avoid the mountains, the proposed railroad would have to swing south into what was then Mexican territory. Gadsden, a South Carolinan, was an ardent supporter of a southern railroad, but he envisioned it being built to Charleston, South Carolina. Gadsden was interested in this purchase since he acquired shares of the railroad company that would unite Texas and California.

Controversy

As originally envisioned, the purchase would have encompassed a much larger region, extending far enough south to include most of the current Mexican states of Coahuila, Chihuahua, Sonora, Nuevo León, and Tamaulipas as well as all of the Baja California peninsula. These original boundaries were opposed not only by the Mexican people but also by anti-slavery U.S. Senators who saw the purchase as tantamount to the acquisition of more slave territory. Even the small strip of land that was ultimately acquired was enough to anger the Mexican people, who saw Santa Anna's actions as yet another betrayal of their country and watched in dismay as he squandered the funds generated by the Purchase. The Gadsden Purchase helped to end Santa Anna's political career.

Outraged at the reduced size of the purchase, American filibuster William Walker led an army from California into Sonora and declared independence for the Republic of Sonora consisting of the remaining non-purchased state of Sonora and the whole of the Baja California peninsula. Lack of supplies and a strong resistance by the Mexican government quickly forced Walker to retreat. Back in California, he was put on trial for conducting an illegal war. The jury took eight minutes to acquit him.

The purchased lands were initially appended to the existing New Mexico Territory. To help control the new land, the United States Army established Fort Buchanan on Sonoita Creek in present-day southern Arizona on November 17 1856. 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 of the New Mexico Territory. 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.

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

U.S. statehood

In 1861, during the American Civil War, the Confederacy 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 U.S. 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 in the lower 48 to receive statehood.
