What does "Manifest Destiny" refer to?

"Manifest Destiny" refers to the belief in the inevitable territorial expansion of the United States across North America. This concept emerged in the 19th century and was driven by the notion that it was the divine right and destiny of the United States to expand its territory from the Atlantic to the Pacific Ocean. This belief not only justified the westward movement of settlers but also played a significant role in various historical events, such as the annexation of Texas, the Oregon Trail migration, and the Mexican-American War.

Understanding this concept is crucial as it highlights the motivations behind U.S. expansionist policies and their impact on Native American populations, foreign relations, and the overall shaping of American identity during that period. The ideology of Manifest Destiny was not just a political aim but also intertwined with ideas of American exceptionalism, suggesting that the U.S. had a mission to spread democracy and civilization.
