Final answer:
The Louisiana Purchase had a significant impact on slavery, raising questions about the expansion of slavery in the newly acquired territory and fueling the growth of plantation slavery. Tensions surrounding slavery intensified as a result.
Step-by-step explanation:
The Louisiana Purchase of 1803 had a significant impact on slavery. The acquisition of the Louisiana Territory, which more than doubled the size of the United States, raised questions about whether the new lands would be slave or free. The purchase also fueled the rapid expansion of plantation slavery, driven by the invention of the cotton gin. While some believed that slavery was a temporary institution that would soon die out, tensions rose with the Louisiana Purchase, contributing to a sectional national debate on slavery.
