Difficulty: MediumIdeological and Legal Debates over Slavery

Read the passage below and answer the question that follows.

"How can the Union be saved? To this I answer, there is but one way by which it can be, and that is by a simple act of justice, and a duty; to give to the South an equal right in the acquired territory, and to do her duty by causing the stipulations relative to fugitive slaves to be faithfully fulfilled—to cease the agitation of the slave question, and to provide for the insertion of a provision in the Constitution, by an amendment, which will restore to the South, in substance, the power she possessed of protecting herself before the equilibrium between the two sections was destroyed..."
— John C. Calhoun, Senator from South Carolina, speech to the Senate, March 4, 1850

Which of the following developments in the 1850s most directly threatened the conditions Calhoun argued were necessary to save the Union?

  1. A
    The escalation of sectional tensions driven primarily by disputes over federal import tariffs rather than debates over slavery.
  2. B
    The adoption of popular sovereignty, which authorized the President to directly determine whether a new territory would permit slavery.
  3. The rise of the Republican Party, which campaigned on a platform opposing the expansion of slavery into the Western territories.Answer
  4. D
    The proposal by Northern free-soilers to transition Southern plantations from chattel slavery to a system of colonial-style indentured servitude.

Answer

The rise of the Republican Party, which campaigned on a platform opposing the expansion of slavery into the Western territories.
The correct answer is correct because Calhoun explicitly demanded that the South be given an equal right in the acquired territory (allowing slaveholders to bring their enslaved property into new territories) and that the North cease the agitation of the slave question. The rise of the Republican Party, which won the presidency in 1860 on a platform dedicated to halting the expansion of slavery, directly rejected Calhoun's demands and intensified the sectional division.

Step-by-Step Solution

1
Analyze the stimulus to determine Calhoun's requirements for saving the Union.
Calhoun argues that the Union can only be saved if the North allows slavery in the acquired territories, enforces the Fugitive Slave Clause, ceases agitation over slavery, and restores the political balance of power between the sections.
Understanding the author's argument is essential for identifying which subsequent historical development directly contradicted it.
2
Evaluate the political developments of the 1850s against Calhoun's requirements.
The Republican Party was formed in 1854 on a platform dedicated to stopping the westward expansion of slavery, which directly rejected Calhoun's demand for Southern rights in the territories and escalated agitation on the slavery question.
This step connects Calhoun's ideological stance to the key political shift that ultimately led to the election of 1860 and secession.
3
Differentiate between the correct answer and distractors representing common historical misconceptions.
Rule out options that incorrectly focus on tariffs as the primary cause of the 1850s crisis, misdefine popular sovereignty as an executive power, or conflate free labor goals with indentured servitude.
This ensures the final choice rests on accurate historical definitions and causal relationships.
