*Question*Explain the philosophy of "Manifest Destiny." What forces created this concept?
*Answer*“Manifest Destiny” is the belief that the U.S. was destined to secure territory from “sea to sea” (the Atlantic to the Pacific), which drove the acquisition of territory. Journalist John O'Sullivan in the New York Democratic Review in 1845 wrote in favor of the U.S. annexing Texas (was independent) and gave the movement its name.
