Resolved to serve only one term, Polk acted swiftly to fulfill his campaign promises. In just four years, he oversaw annexation of Texas, settlement of the Oregon boundary dispute with Great Britain, reestablishment of an independent treasury system, and acquisition of territory from Mexico that eventually became California, New Mexico, Arizona, Nevada, Utah, and parts of Colorado and Wyoming. The former Mexican land came as part of the 1848 Treaty of Guadalupe Hidalgo, settling the Mexican-American War (fought from April 1846 to February 1848).
