George Bancroft, Secretary of the Navy under Polk, recalled many years later that Polk had announced in 1845 near the beginning of his presidency that the acquisition of California was one of "four great measures" he hoped to accomplish while in office. Historian Sam W. Haynes has identified Polk as a "fitting representative" of the "expansionist impulse" known as Manifest Destiny. As a condition of the Treaty of Guadalupe Hidalgo, which ended the Mexican War, the government of Mexico ceded to the U.S. a vast amount of territory that included the present state of California. Hope this helps! PLZ mark brainliest!
