Short Answer Question · Unit 4
"Our manifest destiny is to overspread the continent allotted by Providence for the free development of our yearly multiplying millions. It is a natural right, and it is our duty to extend the area of freedom across the continent."
— John L. O'Sullivan, "Annexation," 1845
A
Briefly describe ONE belief about American expansion expressed in the passage.

✓ Model answer (earns the point)

O'Sullivan believed westward expansion was divinely ordained and a natural right of the United States — he framed it as "allotted by Providence" (i.e., God-given) and called it a "duty to extend the area of freedom" across the continent, treating expansion as both a religious mission and an unstoppable historical force.

Why it scores: Identifies a specific belief drawn directly from the passage (expansion as divinely ordained and inevitable) with concrete language. "He liked expansion" would be too vague to earn the point.
B
Explain ONE cultural or social effect of European perceptions of Native Americans on Native peoples during 1800–1848.

✓ Model answer (earns the point)

Manifest Destiny ideology justified the annexation of Texas (1845) and the Mexican-American War (1846–1848), which added the entire Southwest to the United States. By framing expansion as a God-given right and natural duty, politicians and the public dismissed Mexican territorial claims and Native sovereignty as obstacles to be overcome — the war that followed gave the U.S. California, Arizona, New Mexico, and most of the modern Southwest.

Why it scores: Names a specific political effect (Texas annexation and Mexican-American War) with clear causal reasoning explaining how the ideology drove the policy.
C
Explain ONE economic effect of early Spanish colonization on Native societies in the period 1800–1848.

✓ Model answer (earns the point)

The 1830 Indian Removal Act and the Cherokee Trail of Tears (1838–39) forced the violent relocation of tens of thousands of Native Americans, destroying communities and killing about 4,000 Cherokees alone. Manifest Destiny's ideology of an inevitable westward-marching white nation made Native presence in the East intolerable; even after the Supreme Court ruled FOR the Cherokee in Worcester v. Georgia, Jackson ignored the ruling and proceeded with removal — devastating Native cultural and social structures.

Why it scores: Names a specific effect (Trail of Tears removal devastating Cherokee community) with clear causal reasoning connecting Manifest Destiny ideology to Indian Removal policy.
