What was the primary ideology behind Manifest Destiny?

The primary ideology behind Manifest Destiny was the belief that U.S. expansion was justified and inevitable. This concept, which gained prominence in the 19th century, reflected a strong sense of nationalism and the idea that Americans were destined to expand their territory across the North American continent. Proponents of Manifest Destiny believed that it was both a moral duty and a divine right to spread democracy and capitalism, which they viewed as superior to other forms of governance and economy.

This belief was not merely about claiming new lands; it also encompassed a vision of cultural and civilizational supremacy. The notion that Americans could bring progress and enlightenment to what they considered less developed regions reinforced the justification for territorial expansion, often at the expense of Native American peoples and other nations.

Other ideologies mentioned, such as isolationism, would conflict with the very premise of Manifest Destiny, which promoted active expansion rather than withdrawal from international affairs. Federalism relates more to the balance of power between state and national governments and does not directly address territorial expansion. Agrarianism focuses on agricultural society and practices rather than the broader, more expansive ideals associated with Manifest Destiny. Therefore, the correct answer captures the essence of a vision that sought to extend American influence and territory across the continent.
