Explanation:The name of the US acquisition is La Mesilla, a region that includes the states of Arizona and New Mexico and is known as Gadsden Purchase, in honor of James Gadsden, United States Ambassador to Mexico and who signed the treaty for his purchase on December 30, 1853.
The reason for this purchase was the creation of a railroad route.
The United States paid Mexico for this purchase the sum of 10 million dollars.
Gasden Purchase--the strip of land purchased from Mexico in 1853 was negotiated by James Gasden.
The US wanted this strip of land to complete the southern branch of the Transcontinental Railroad. Gasden was the minister to Mexico and sent to negotiate the purchase of the land as well as create a final border agreement with Mexican president, Santa Anna. The land was purchased for $10 million and settled the US-Mexico border.
