- Secondary-source excerpt: Writing about the Mexican-American War (1846–1848), a historian argues that the conflict grew out of U.S. expansionism after the annexation of Texas and a dispute over whether the border lay at the Nueces River or the Rio Grande. The author adds that President Polk's decision to send troops into the contested zone helped trigger fighting, after which U.S. forces captured Mexico City and the Treaty of Guadalupe Hidalgo transferred vast northern Mexican territories to the United States.
Which statement best reflects the historian's interpretation of the war's primary cause?
Answer: A border dispute amplified by U.S. expansionist aims after Texas annexation
This question tests understanding of the primary causes of the Mexican-American War (1846-1848). The historian's excerpt emphasizes that the conflict grew from U.S. expansionist aims following Texas annexation, combined with a border dispute over whether Texas extended to the Nueces River or Rio Grande. President Polk's decision to send troops into the contested zone between these rivers helped trigger the fighting that led to U.S. forces capturing Mexico City and the Treaty of Guadalupe Hidalgo transferring vast Mexican territories to the United States. Choice B correctly identifies this as 'a border dispute amplified by U.S. expansionist aims after Texas annexation.' Choice A incorrectly suggests Mexico tried to reannex the Louisiana Purchase, which was never Mexican territory.
- Secondary-source excerpt: A historian claims that opposition to the Mexican-American War included moral and political critiques. The author highlights arguments that the war was unjust, that it would spread slavery, and that it represented an abuse of executive power.
Which individual is most closely associated with the type of moral critique described?
Answer: Henry David Thoreau, who protested the war through civil disobedience
This question assesses knowledge of moral opposition to the Mexican-American War. The historian describes opposition that included moral and political critiques, highlighting arguments that the war was unjust, would spread slavery, and represented abuse of executive power. Choice A correctly identifies Henry David Thoreau as most closely associated with the type of moral critique described. Thoreau famously spent a night in jail for refusing to pay taxes that supported what he viewed as an unjust war, and wrote 'Civil Disobedience' about this experience. Choice B incorrectly states that Andrew Jackson supported nullification, when he actually opposed it during the Nullification Crisis.
- Secondary-source excerpt: A scholar contends that the Mexican-American War increased U.S. confidence in its military and national mission, but also provoked debate about whether republican institutions could coexist with territorial conquest. The author notes that some critics feared empire would corrupt the republic.
Which earlier American debate most closely parallels the concern about conquest corrupting republican government?
Answer: The controversy over the annexation of the Philippines after the Spanish-American War
This question tests understanding of debates about territorial conquest and republican government. The scholar contends that the Mexican-American War increased U.S. confidence but also provoked debate about whether republican institutions could coexist with territorial conquest, with some critics fearing empire would corrupt the republic. Choice D correctly identifies the controversy over annexing the Philippines after the Spanish-American War as the later debate that most closely parallels this concern. Anti-imperialists argued that ruling overseas territories would undermine American democratic principles. Choice A incorrectly references constitutional ratification debates, which concerned federalism rather than territorial conquest.
- Secondary-source excerpt: A historian contends that Mexico entered the war politically divided and financially strained, limiting its ability to sustain long campaigns. The author argues that internal instability hindered consistent strategy and supply.
Which factor in Mexico would most directly align with the historian's explanation?
Answer: Frequent changes in national leadership and competing factions
This question tests understanding of Mexican disadvantages during the Mexican-American War. The historian contends that Mexico entered the war politically divided and financially strained, limiting its ability to sustain long campaigns, with internal instability hindering consistent strategy and supply. Choice A correctly identifies frequent changes in national leadership and competing factions as the factor that would most directly align with the historian's explanation. Mexico experienced significant political instability during this period, with frequent government changes undermining war efforts. Choice B incorrectly describes a unified political system with stable revenues and professional army, which contradicts the historian's assessment of Mexican weaknesses.
- Secondary-source excerpt: In assessing the Mexican-American War, a scholar argues that Manifest Destiny ideology encouraged many Americans to view continental expansion as both inevitable and virtuous. The author suggests this belief helped generate popular support for war even as some opponents warned it would worsen sectional tensions.
Which piece of evidence would best support the scholar's claim about Manifest Destiny shaping support for the war?
Answer: Newspaper editorials describing U.S. expansion to the Pacific as a providential mission
This question tests understanding of how Manifest Destiny ideology supported the Mexican-American War. The scholar argues that Manifest Destiny encouraged Americans to view continental expansion as 'both inevitable and virtuous,' helping generate popular support for war despite opponents' warnings about sectional tensions. Choice B correctly identifies newspaper editorials describing U.S. expansion to the Pacific as a providential mission as the best evidence supporting the scholar's claim about Manifest Destiny shaping support. Such editorials would demonstrate the ideological framework that made expansion seem divinely ordained. Choice A incorrectly references campaign speeches about the national bank, which was not related to territorial expansion ideology.
- Secondary source excerpt (75–125 words): The Mexican-American War's aftermath reshaped the political map of North America. By acquiring California and the Southwest, the United States gained Pacific ports and new resources, but also inherited complex questions about the status of Mexican residents and Indigenous peoples in the ceded lands. The treaty promised protection of property and certain civil rights, yet enforcement was uneven, and legal disputes over land grants became common. Meanwhile, the new territory forced national politicians to confront whether Congress could restrict slavery's expansion—an issue that fueled party realignment and contributed to the breakdown of earlier compromises.
Which issue in the excerpt most directly connects the war's consequences to the coming of the Civil War?
Answer: The debate over whether slavery would be permitted in territories acquired from Mexico
This question examines the connection between the Mexican-American War and the Civil War. The excerpt explains how territorial acquisition forced national politicians to confront whether Congress could restrict slavery's expansion into new territories, an issue that broke down earlier compromises and fueled party realignment. The correct answer A identifies the slavery expansion debate as the most direct link to the Civil War's origins. Option B incorrectly suggests repealing the Bill of Rights, C invents California's secession, D contradicts the actual increase in Pacific interests, and E anachronistically mentions Reconstruction which followed the Civil War.
- Secondary-source excerpt: A historian writes that the U.S. government's insistence on the Rio Grande as Texas's boundary was central to the road to war. The author notes that Mexico recognized the Nueces River as the boundary and viewed U.S. troops near the Rio Grande as an invasion.
Which geographic claim is at the core of the dispute described?
Answer: Whether the Texas-Mexico border lay at the Nueces River or the Rio Grande
This question tests knowledge of the specific boundary dispute that helped trigger the Mexican-American War. The historian writes that the U.S. government's insistence on the Rio Grande as Texas's boundary was central to the road to war, while Mexico recognized the Nueces River as the boundary and viewed U.S. troops near the Rio Grande as invasion. Choice B correctly identifies the question of whether the Texas-Mexico border lay at the Nueces River or Rio Grande as the geographic claim at the core of the dispute. This boundary disagreement provided the immediate pretext for hostilities. Choice A incorrectly references whether Texas extended north to the Arkansas River, which was not part of the border dispute with Mexico.
- Secondary-source excerpt: A scholar argues that the Mexican-American War helped solidify the United States as a continental power, but also left unresolved tensions about the limits of expansion. The author notes that some expansionists sought even more territory, while others feared overreach.
Which proposal most directly reflects the 'even more territory' impulse after the war?
Answer: Calls by some Americans to annex 'All Mexico'
This question tests understanding of expansionist sentiment beyond the Mexican-American War's actual territorial gains. The scholar argues the war solidified the United States as a continental power but left unresolved tensions about expansion limits, noting that some expansionists sought even more territory while others feared overreach. Choice A correctly identifies calls by some Americans to annex 'All Mexico' as the proposal that most directly reflects the 'even more territory' impulse after the war. The 'All Mexico' movement wanted to absorb all Mexican territory, not just the northern regions actually acquired. Choice B incorrectly suggests a plan to return Texas to Mexico, which contradicts expansionist sentiment.
- Secondary-source excerpt: A historian argues that the Mexican-American War's outbreak was tied to a contest over legitimacy: Mexico viewed Texas as a rebellious province, while the United States treated Texas as a sovereign nation eligible for annexation. The author suggests these conflicting views made compromise difficult.
Which diplomatic position best reflects Mexico's view described in the excerpt?
Answer: Mexico refused to recognize Texas independence and treated annexation as aggression
This question assesses understanding of the diplomatic legitimacy dispute underlying the Mexican-American War. The historian argues the war's outbreak was tied to conflicting views of legitimacy: Mexico viewed Texas as a rebellious province, while the United States treated Texas as a sovereign nation eligible for annexation, making compromise difficult. Choice A correctly identifies Mexico's position that it refused to recognize Texas independence and treated annexation as aggression as the diplomatic stance that best reflects Mexico's view. Mexico never acknowledged Texas independence after 1836. Choice B incorrectly suggests Mexico recognized Texas independence but demanded Texas annex the United States, which makes no diplomatic sense.
- Secondary source excerpt (75–125 words): In assessing responsibility for the Mexican-American War, scholars often highlight the interaction of Mexican political instability and U.S. pressure. Mexico faced frequent changes in leadership and struggled to respond coherently to Texas annexation and U.S. offers to buy northern provinces. In Washington, President Polk treated territorial acquisition as a central goal and used the boundary dispute to justify military action after the first skirmishes. The resulting U.S. victory forced Mexico to accept major land cessions. Debates over whether the war was defensive or aggressive persisted, shaping later arguments about American imperialism.
Which interpretation of U.S. motives is most consistent with the excerpt?
Answer: The United States sought territorial acquisition and used the boundary dispute to justify war
This question assesses interpretations of U.S. motives in the Mexican-American War. The excerpt presents a scholarly view that President Polk treated territorial acquisition as a central goal and used the boundary dispute as justification for military action after initial skirmishes. The correct answer B accurately reflects this interpretation that the United States sought territorial gains and exploited the border dispute to justify war. Options A, C, D, and E all present false scenarios - defending Canada from Mexico, supporting Mexican abolition, restoring Spanish rule, or ending African colonization - none of which reflect actual U.S. motives.
- Secondary-source excerpt: A historian contends that President Polk framed the outbreak of the Mexican-American War as a defensive response to Mexican aggression, but critics in Congress questioned whether U.S. troops had been deliberately placed in harm's way in a disputed area. The author notes that these critics feared the war was intended to gain territory.
Which group most prominently voiced the criticism described in the excerpt?
Answer: Whigs who argued Polk had provoked hostilities to expand U.S. territory
This question evaluates knowledge of political opposition to the Mexican-American War. The historian describes how President Polk framed the war as defensive against Mexican aggression, but critics in Congress questioned whether U.S. troops had been deliberately placed in harm's way in the disputed area, fearing the war was intended to gain territory. Choice B correctly identifies Whigs as the group that most prominently argued Polk had provoked hostilities to expand U.S. territory. The Whig Party consistently opposed what they saw as Polk's aggressive expansionism and his justification for the war. Choice A incorrectly references Federalists opposing the Louisiana Purchase, which occurred decades earlier.
- Secondary-source excerpt: "Military victory did not settle the moral debate at home. Some Americans, including a number of writers and politicians, saw the war as evidence that the republic was abandoning its professed ideals by waging conquest against a weaker neighbor." Which individual is most closely associated with this kind of antiwar critique during the Mexican-American War era?
Answer: Henry David Thoreau, who protested the war and slavery in 'Civil Disobedience.'
This question tests knowledge of antiwar critics during the Mexican-American War. The excerpt describes how some Americans, including writers and politicians, saw the war as abandoning republican ideals by waging conquest against a weaker neighbor. Answer A correctly identifies Henry David Thoreau, who famously protested the war and slavery in his essay "Civil Disobedience," as the individual most associated with this moral critique. Answer B is wrong because James K. Polk was the president who initiated the war and defended it, not a critic who saw it as abandoning American ideals.
- Secondary-source excerpt: A historian notes that the Mexican-American War added vast lands but did not resolve how they would be integrated into the Union. The author argues that the political struggle over these lands contributed to rising talk of secession in the 1850s.
Which event most directly illustrates escalating sectional conflict linked to disputes over western territories?
Answer: Violence in 'Bleeding Kansas' after the Kansas-Nebraska Act
This question evaluates understanding of how unresolved territorial questions from the Mexican-American War contributed to escalating sectional conflict. The historian notes the war added vast lands but did not resolve how they would be integrated into the Union, arguing that political struggle over these lands contributed to rising talk of secession in the 1850s. Choice A correctly identifies violence in 'Bleeding Kansas' after the Kansas-Nebraska Act as the event that most directly illustrates escalating sectional conflict linked to disputes over western territories. The Kansas violence demonstrated how territorial slavery questions led to actual bloodshed. Choice B incorrectly references the Salem witch trials, which occurred in colonial times and were unrelated to territorial slavery disputes.
- Secondary-source excerpt: A historian notes that the Mexican-American War produced a large territorial cession to the United States, but the author emphasizes that the conflict also raised questions about the status and rights of Mexican residents in the ceded lands. The treaty promised protections, yet implementation often fell short.
Which outcome best illustrates the gap described in the excerpt?
Answer: Lengthy legal disputes and loss of land by some Mexican Americans despite treaty guarantees
This question assesses understanding of how the Mexican-American War's aftermath affected Mexican residents in ceded territories. The historian notes that while the treaty promised protections for Mexican residents' rights, 'implementation often fell short,' creating a gap between promises and reality. Choice B correctly identifies lengthy legal disputes and loss of land by Mexican Americans despite treaty guarantees as the outcome that best illustrates this gap. Many Mexican landowners faced expensive English-language court proceedings and complex legal requirements that often resulted in land loss despite treaty protections. Choice A incorrectly suggests widespread enforcement of equal land titles, which contradicts the historian's point about implementation falling short.
- Secondary-source excerpt: A scholar argues that the Mexican-American War's territorial gains contributed to the intensification of sectional conflict by upsetting the balance between free and slave states and raising fears of political domination by one section. The author notes that even the process of organizing territories became contentious.
Which statement best explains why territorial organization became contentious?
Answer: Because decisions about slavery in new territories affected the balance of power in Congress
This question tests understanding of why territorial organization became controversial after the Mexican-American War. The scholar argues the war's territorial gains contributed to intensified sectional conflict by upsetting the balance between free and slave states and raising fears of political domination, making even territorial organization contentious. Choice B correctly explains that decisions about slavery in new territories affected the balance of power in Congress. Each new state's slave or free status would alter Senate representation and national political influence. Choice A incorrectly suggests the Constitution required all territories to ban slavery automatically, which was not the case.
- Secondary-source excerpt: One historian argues that President Polk's negotiating strategy combined military pressure with diplomacy. The author notes that Polk sent an envoy to seek the purchase of California and New Mexico, but after fighting began, the United States used battlefield success to demand a larger settlement.
Which concept best captures the strategy described in the excerpt?
Answer: Using military victory to strengthen bargaining leverage in treaty negotiations
This question tests understanding of President Polk's diplomatic-military strategy during the Mexican-American War. The historian argues that Polk combined military pressure with diplomacy, initially sending an envoy to purchase California and New Mexico, but after fighting began, the United States used battlefield success to demand a larger settlement. Choice B correctly identifies 'using military victory to strengthen bargaining leverage in treaty negotiations' as the concept that best captures this strategy. Polk demonstrated how military success could enhance diplomatic positions. Choice A incorrectly describes dollar diplomacy, which was a later 20th-century policy approach.
- Secondary-source excerpt: In one interpretation, the Mexican-American War highlighted the growing power of the federal government to project military force far from U.S. borders. The author points to the ability to mobilize volunteers and regular troops for campaigns deep in Mexico.
Which earlier conflict most similarly demonstrated U.S. capacity to project force beyond its borders, though on a smaller scale?
Answer: The War of 1812 invasion attempts into Canada
This question assesses understanding of how the Mexican-American War demonstrated federal power projection capabilities. The historian notes that the war highlighted the federal government's growing power to project military force far from U.S. borders, pointing to the ability to mobilize volunteers and regular troops for campaigns deep in Mexico. Choice B correctly identifies the War of 1812 invasion attempts into Canada as the earlier conflict that most similarly demonstrated U.S. capacity to project force beyond its borders, though on a smaller scale. Both conflicts involved military operations in foreign territory requiring logistical coordination. Choice A incorrectly describes the Quasi-War as fought primarily on the Atlantic, which did not involve territorial invasion.
- Secondary-source excerpt: A historian argues that the Mexican-American War altered U.S. relations with Native peoples in the Southwest by bringing new federal authority and settlers into the region. The author notes that conflicts over land and resources increased as U.S. governance expanded.
Which consequence best aligns with the excerpt's claim?
Answer: Increased U.S. military campaigns and treaty pressures on Native nations in the newly acquired Southwest
This question assesses understanding of how the Mexican-American War affected U.S.-Native American relations in the Southwest. The historian argues that the war altered these relations by bringing new federal authority and settlers into the region, with conflicts over land and resources increasing as U.S. governance expanded. Choice A correctly identifies increased U.S. military campaigns and treaty pressures on Native nations in the newly acquired Southwest as the consequence that best aligns with this claim. U.S. territorial control led to intensified pressure on Native peoples. Choice B incorrectly suggests the end of all Native displacement policies after 1848, which contradicts historical patterns of continued displacement.
- Secondary-source excerpt: A scholar contends that the Mexican-American War's legacy included sharpening U.S. debates over race and citizenship, as Americans argued about incorporating Mexican residents and governing culturally diverse territories. The author suggests these debates influenced later attitudes toward immigration and empire.
Which later event most directly reflects similar debates about governing nonwhite populations after territorial acquisition?
Answer: Debates over U.S. rule in Puerto Rico and the Philippines after 1898
This question tests understanding of how Mexican-American War debates about race and citizenship influenced later American attitudes. The scholar contends the war's legacy included sharpening debates over race and citizenship as Americans argued about incorporating Mexican residents and governing culturally diverse territories, suggesting these debates influenced later attitudes toward immigration and empire. Choice A correctly identifies debates over U.S. rule in Puerto Rico and the Philippines after 1898 as the later event that most directly reflects similar debates about governing nonwhite populations after territorial acquisition. Both situations involved questions about incorporating diverse populations. Choice B incorrectly references the Boston Tea Party, which was about taxation rather than racial governance issues.
- Secondary-source excerpt: A historian argues that the Mexican-American War was part of a broader pattern of U.S. territorial expansion in the 1840s. The author notes that in the same decade the United States also resolved a boundary dispute with Britain in the Pacific Northwest.
Which event best fits the pattern described?
Answer: The Oregon Treaty (1846) setting the boundary at the 49th parallel
This question assesses knowledge of 1840s territorial expansion patterns beyond the Mexican-American War. The historian argues the Mexican-American War was part of broader U.S. territorial expansion in the 1840s, noting that in the same decade the United States also resolved a boundary dispute with Britain in the Pacific Northwest. Choice A correctly identifies the Oregon Treaty (1846) setting the boundary at the 49th parallel as the event that best fits this pattern. The Oregon resolution occurred simultaneously with Mexican War tensions, demonstrating comprehensive expansionist goals. Choice B incorrectly states the Treaty of Ghent ended the Revolutionary War, when it actually ended the War of 1812.
