In March of 1855, Kansas was split. The Governemt had decided to give the option of slave state or non-slave state to the people. The anti-slavery states were urging their supporters to move to Kansas. The pro-slavery states were doing the same.
Dred Scott Case
The result of the vote ended up favoring the Pro-Slavery candidates. They destroyed all anti-slavery propaganda and destroyed newspapers. The aboltionist's were not happy.
The two sides fought viciously with each other. Both sides lost most of their men over the decision. The fighting continued for many years after the decision.
Dred Scott Decision
Dred Scott was a slave for John Emerson. While Emerson was in the war, Scott accompanied him and the pair eventually returned to Missouri. After Emerson died, Scott decided to sue for his freedom.
I want freedom!!!
Eventually, the case was brought to the Supreme Court. Roger B. Taney argued on the side of the prosecution. He said that no black man has any rights that a white man should acknowledge.
Aboltionists everywhere were outraged. The decision to not grant freedom brought a great uproar within the anti-slavery community. They saw this as an opportunity for action.
