Manifest Destiny was a term that described the widespread belief in the mid-19th century that the United States had a special mission to extend west.
Explanation:
The concept was not particularly new, as Americans were already exploring and settling west, first across the Appalachian Mountains in the late 1700s and then, beyond the Mississippi River in the early 1790s.
But by presenting the concept of Western expansion as one's religious mission, the idea of manifest destiny struck a chord.
Although the phrase manifest destiny seems to have taken on a public mood in the mid-19th century, it has not been observed with universal approval.
Some at the time thought that they were simply putting pseudo-religious fields on a radiant craving and conquest.
