What was James Buchanan noted for?

Answer 1

The Supreme Court's Dred Scott decision, for which Buchanan had secretly lobbied and which denied Congress's power to ban slavery in the western territories, unleashed an unprecedented wave of anger in the North. When Buchanan supported pro-slavery forces in the Kansas Territory, that anger rose to a fever pitch. In response, the South's militance in defense of slavery waxed ever stronger, and by the end of Buchanan's term, the long-feared specter of war between the two sections was turning into a reality.
