Northerners resent Southerners for making them participate in the capture of runaway enslaved people. -
Kansas-Nebraska Act
Pro-slavery and anti-slavery Americans fight each other to gain political control of a territory. -
Dred Scott decision
Anti-slavery Northerners feel that the Supreme Court is too pro-slavery. -
Election of 1860
(Note: The provided options do not directly connect to this event; it was significant as it led to the secession of Southern states due to Lincoln's election, which they viewed as a threat to slavery.)
