What does the term "Manifest Destiny" refer to?

The term "Manifest Destiny" refers to the belief that the United States was destined to expand across North America, spreading its ideals and institutions. This concept emerged in the 19th century and was rooted in a sense of American exceptionalism, suggesting that it was both a right and a duty for the U.S. to extend its territory and influence from the Atlantic to the Pacific. This belief played a significant role in the westward expansion of the nation, leading to events such as the annexation of Texas, the Oregon Trail migration, and the outcomes of the Mexican-American War. The ideology encapsulated the conviction that American settlers were divinely ordained to settle the land, which in turn justified actions that often led to conflicts with Native American tribes and other nations.
