Answer:
Two answers:
- Bleeding Kansas
- John Brown's raid on Harper's ferry
Explanation:
Bleeding Kansas resulted after congress granted Kansas the permission to vote whether it'd be admitted into the union as a free or slave state. Settlers immediately flocked to Kansas to cast illegal votes either in favor for or against slavery, resulting in a bloody conflict.
Enter John Brown, a crazy bearded guy who absolutely despises slavery, and in an attempt to start a slave uprising led a raid on a weapon depot.
This sparked fears of slave rebellions for Southern cotton planters...
