Which slogan emphasized the idea of manifest destiny during the imperialist era?

The slogan that emphasized the idea of manifest destiny during the imperialist era is "Manifest Destiny: To overspread the continent allotted by Providence." This phrase encapsulates the belief held by many Americans in the 19th century that the United States was destined to expand its territory across the North American continent. Manifest destiny was not just about geographic expansion; it also reflected a sense of cultural superiority and a mission to spread democratic values and institutions.

By using language like "overspread the continent" and "allotted by Providence," this slogan invokes the idea that the expansion was divinely sanctioned, suggesting that it was not only a right but a duty of Americans to extend their influence. This perspective fueled various actions taken by the U.S. during its period of imperialism, including the acquisition of territories through wars, treaties, and colonization, asserting America's presence and control over vast areas.

The other options do not align closely with the distinct notion of manifest destiny. While "Land of the Free, Home of the Brave" highlights American values, it does not specifically reference the expansionist ideology. "Peace without conquest" suggests a more diplomatic approach to foreign relations that contrasts with the aggressive territorial ambitions implied in manifest destiny. "America's Role in the World"
