The term "Manifest Destiny" refers to the 19th-century doctrine or belief that the expansion of the United States throughout the American continents was both justified and inevitable. This idea held that it was the destiny of the United States to expand its territory across North America, which was seen as a divine right and a cultural obligation. Proponents of Manifest Destiny believed that such expansion was not only beneficial for Americans but also for the world, promoting democracy and civilization.

This belief influenced various key events in U.S. history, such as the westward migration, the annexation of territories like Texas, and the concept of the United States acquiring land all the way to the Pacific Ocean. Manifest Destiny had significant implications for relations with Native American tribes and neighboring countries, leading to conflicts and territorial disputes. Understanding Manifest Destiny is crucial for grasping how it shaped the nation’s geographic and political development during the 19th century.
