What does Manifest Destiny reflect about 19th century beliefs?

Manifest Destiny embodies the belief that the expansion of the United States across the North American continent was both justified and inevitable. This ideology was rooted in the notion that American settlers were destined to expand their civilization and way of life, often viewing it as benevolent and a divine right. This led to the implication that imperialistic expansion was necessary for the growth and prosperity of the nation, placing a moral justification on the acquisition of new territories.

The focus on expansion reflects the mindset of that era, in which many believed that it was their obligation to spread democracy and capitalism, framing imperialistic actions in a positive light. It was less about the nuances of technological advancements or equality among various ethnic groups, and more heavily centered on the belief in American exceptionalism and the right to conquer and govern lands inhabited by others, including Native American populations.

While other options touch on significant elements of 19th-century development, they do not capture the core sentiment surrounding Manifest Destiny as powerfully as the idea of expansion as a necessary and benevolent action.
