Which factor contributed to sectional tensions after the Louisiana Purchase?

• A. Differences in climate
• B. Imposition of federal holidays
• C. Slavery expansion into new territories
• D. Conflict with France over fishing rights

Answer: (C)

Expansion of the nation into the vast lands acquired in the Louisiana Purchase brought the question of slavery into every new territory and eventual state. If slavery could spread into these areas, the balance of political power in Congress between free and slave states would shift, influencing national policy and regional influence. Northern opponents feared the spread of slavery would entrench a labor system they believed was incompatible with free labor in new lands, while Southern leaders pushed to extend slavery to preserve economic interests and political clout. These disagreements produced persistent sectional hostility and long road to legislative attempts to resolve the balance, such as measures that tried to regulate or limit slavery in new territories. The other options don’t connect to the driving political fault line of the era—climate differences, federal holidays, or disputes with France over fishing rights did not spark the same national divide over slavery and political power in new territories.
