In 1854, The Gadsden Purchase was made and the first draft was signed by James Gadsden.
It was an agreement between The Unites States and Mexico where The US purchased a 29,670-square-mile region of present day southern Arizona and southwestern New Mexico.
Gadsden wanted to connect all the southern railroads into one section as he felt that the Southern part was suffering due to the increase of railroad construction in the North and this was bypassing all the trading, farming and manufacturing businesses from the South.
