Debates over the expansion of slavery into new territories

Debates over the expansion of slavery into new territories created turmoil in national politics. A major milepost on the way to war was the Supreme Court's 1857 Dred Scott decision, which said that slaves could not win their freedom simply by crossing into a free state. Around this time, many northern voters came to view the Democratic Party as pro-southern. The Republican Party, which rapidly gained strength in the North after its creation in the mid-1850s, adamantly opposed extending slavery into the territories and won virtually no support in the South.
