Gadsden Purchase
The Gadsden Purchase is a region of present-day southern Arizona and southwestern New Mexico that was purchased by the United States in a treaty signed by James Gadsden, the American ambassador to Mexico at the time, on December 30, 1853. It was then ratified, with changes, by the US Senate on April 25, 1854 and signed by President Franklin Pierce, with final approval action taken by Mexico on June 8, 1854. The purchase was the last major territorial acquisition in the contiguous United States, adding a large area to the United States.The above text is a snippet from Wikipedia: Gadsden Purchase
