What does the term "Manifest Destiny" refer to?

The term "Manifest Destiny" refers to the belief that it was the United States' destiny to expand across North America. This ideology emerged in the 19th century and was rooted in a sense of American exceptionalism, reflecting the conviction that it was both justified and inevitable for the nation to expand its territory across the continent. Proponents believed that the expansion was a divine right and duty, leading to increased migration and settlement in Western territories, often at the expense of Native American populations and Mexico.

This concept played a significant role in shaping U.S. policy and expansionist actions, contributing to events such as the annexation of Texas and the Oregon Trail migration. The drive for expansion influenced political, social, and economic dynamics in the country, fostering a narrative that justified territorial conquests as a means to spread democracy and civilization. Understanding Manifest Destiny is crucial for comprehending the complexities of U.S. history and its impact on subsequent events and ideologies in American society.
