What does the term "Manifest Destiny" signify?

The term "Manifest Destiny" refers to the widespread belief during the 19th century that it was both justified and inevitable for the United States to expand its territory across North America. This ideology was rooted in a sense of mission, suggesting that Americans were destined to spread their way of life, culture, and governance. Advocates of Manifest Destiny held that this expansion was preordained and morally right, often intertwining notions of American exceptionalism and a belief in the superiority of their democratic institutions.

Manifest Destiny played a crucial role in motivating westward expansion, leading to significant historical events such as the annexation of Texas, the Oregon Trail migration, and the Mexican-American War. This belief not only justified territorial expansions at the time but also influenced U.S. policies and relationships with Native American populations and other nations.

Understanding this concept is essential, as it reflects how ideas about national identity and destiny shaped the political landscape of the United States during a pivotal era in its history.
