Other forms: manifest destinies
Manifest destiny is the idea that acquiring new territory is both necessary and ordained by a divine power. Manifest destiny was used to justify U.S. expansion in the 19th century.
In 1845, settlers wanted to take land in Texas from the natives living there. They proclaimed: "Our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions." They believed that Providence (God) granted them the right to take land by force, a course of action they felt was both obvious (manifest) and unavoidable (destiny).
