Between 1845 and 1853, the United States acquired land primarily through the annexation of Texas in 1845, the Oregon Treaty with Britain in 1846, and the Mexican-American War (1846-1848), which resulted in the Treaty of Guadalupe Hidalgo. This treaty ceded a vast area of territory from Mexico, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. Additionally, the Gadsden Purchase in 1853 further expanded U.S. territory by acquiring land from Mexico for a southern transcontinental railroad route.
