What term describes the 19th-century belief that U.S. expansion across the North American continent was justified and inevitable?

• A. Imperialism
• B. Manifest Destiny
• C. Westward Expansion
• D. Monroe Doctrine

Answer: (B)

Manifest Destiny is the belief that the United States was destined by Providence to expand across North America, and that this expansion was both morally justified and inevitable. This mindset provided a religious and moral rationale for moves like expanding west, annexing new territories, and engaging in wars or treaties to gain land, because it was framed as a rightful and preordained mission. The idea helped garner broad support for westward movement and shaped policy and public opinion in the 1800s. While imperialism refers to extending power through colonies or rule over other lands, it’s a broader concept and not specifically tied to a divine mandate for continental expansion. Westward Expansion describes the actual movement and settlement westward, but without the explicit claim of a destined, righteous purpose. The Monroe Doctrine focuses on keeping European powers out of the Western Hemisphere, not on justifying continental expansion itself.
