The 13th Amendment abolished slavery in America — but not completely.

Buried in its text is an exception allowing involuntary servitude "as a punishment for crime." That language would become enormously consequential after the Civil War, as Southern states built systems of Black Codes, vagrancy laws, convict leasing, and prison labor that pushed thousands of newly freed Black Americans back into conditions that often looked strikingly similar to slavery.

Bill Bernardoni and Steve Herman are joined first by Damon Root, senior editor at Reason and author of Emancipation War, to trace the political fight that produced the 13th Amendment, Abraham Lincoln's evolution on slavery, and why the amendment's punishment exception was included in the first place.

Then University of Mississippi Associate Professor Marvin King examines what happened after ratification — how Reconstruction gave way to new systems of racial and economic control, how the criminal justice system became part of that structure, and how those choices helped shape inequality for generations.

Finally, the episode looks at the modern effort to remove slavery and involuntary-servitude exceptions from state constitutions — and why, more than 160 years later, the debate over the 13th Amendment is still not over.
