What was Manifest Destiny, and what were its consequences?

• A. A policy to isolate the U.S. from foreign affairs.
• B. A plan to reform the monetary system.
• C. Belief in continental expansion; justified conquest and displacement of Native peoples.
• D. A transportation investment program.

Answer: (C)

Manifest Destiny was a 19th‑century belief that the United States was destined to expand across the North American continent, spreading its system of government and way of life. This conviction helped drive actions that enlarged U.S. borders, such as the annexation of Texas, the settlement of Oregon, and the Mexican‑American War that produced the Mexican Cederal cession. The consequences were substantial: Native peoples were displaced from their ancestral lands through forceful removals and broken treaties, culminating in events like the Indian Removal policy and the Trail of Tears. The expansion also intensified national debates over whether new territories would allow slavery, fueling sectional tensions that contributed to the lead‑up to the Civil War. While it spurred westward settlement and economic growth, it did so at the significant cost of Indigenous nations and ongoing conflicts over sovereignty and resources.
