Open ended:
Explain briefly how the Fugitive Slave Act, Uncle Tom's Cabin, John Brown's raid, and the Dred Scott decision shaped northern public opinion about slavery.
Explain how these events produced tension between the northern and southern states which eventually lead to the Civil War.
At first Northerners didn't mind the South having slaves. After the Fugitive Slave Law, it made them get involved. They weren't allowed to help slaves. In the south, Uncle Tom's Cabin was seen as threatening. In the north, it was praised for its message and helped lay the groundwork for the Civil War. John Brown, in the north, was seen as a hero. In the south, he was seen as something evil. The Dred Scott decision made them think the south wanted slavery all over the nation.
These events produced tension because the North was trying to end slavery and the south didn't want to.
