Final answer:
The issue of slavery caused conflicts between those who opposed it and those who wanted to keep it, leading to the Civil War.
Step-by-step explanation:
The issue of slavery caused conflicts for both those who were opposed to it and those who wanted to keep it. For those who were opposed to slavery, they saw it as a moral wrong and a violation of American values. They believed that all people should be free and have equal rights, and that slavery should be abolished.
On the other hand, those who wanted to keep slavery saw it as a crucial part of their economy and way of life. They argued that prohibiting slavery's expansion went against their property rights and threatened their political and economic liberties.
These conflicts over slavery eventually led to the Civil War, as tensions between the North and the South escalated. While the abolition of slavery on moral grounds played a significant role, the economic disparity tied to slavery also contributed to the divisions between the two sides.
