Episode notes
Election Of Lincoln Triggered Secession
- Lincoln's 1860 election signaled the North could govern without the South, provoking secession.
- Porteus emphasizes it was the first presidential victory built on an explicit anti-slavery platform concentrated in free states.
Southern Theory Of Undivided State Sovereignty
- Southern legal theory claimed undivided state sovereignty and treated the Constitution as a treaty among nations.
- Porteus contrasts this with Madison and Hamilton's intent: Constitution created divided sovereignty and a supreme federal law.
Fugitive Slave Laws Fueled Southern Grievances
- Fugitive slave enforcement was the South's primary grievance, though Northern 'personal liberty' laws were mainly anti-kidnapping protections.
- Porteus points out those laws added due-process rights to prevent free blacks being kidnapped under the 1793 Act.
