Which territory was acquired through the Gadsden Purchase?

The Gadsden Purchase, finalized in 1854, involved the acquisition of land primarily from Mexico, which comprises parts of present-day Arizona and New Mexico. The United States sought this territory for the purpose of facilitating a southern transcontinental railroad route, which would improve transport and commerce. The purchase encompassed approximately 29,670 square miles of land, and it was unique as it was aimed explicitly at addressing issues related to railroad construction, making it a significant moment in the expansion of the country. This acquisition was a continuation of the United States' pursuit of Manifest Destiny, proliferating its territorial claims in the southwest. Benefits from this land acquisition included economic enhancement and strategic expansion, justifying the negotiations and financial agreement involved in the Gadsden Purchase.
