At the start of his presidency in 1861, Abraham Lincoln supported a constitutional amendment that would have kept the federal government from banning slavery in states where it already existed. In just a few short years, he helped secure passage of the 13th Amendment, which ended slavery throughout the United States and all its territories.

Today's guest is Senior Editor Damon Root, whose new book Emancipation War delves into one of the most fascinating chapters of American history. Root and host Nick Gillespie also discuss the Reconstruction period after the Civil War, Root's previous book on Frederick Douglass, and how the Supreme Court is likely to rule in Trump v. Barbara, the birthright citizenship case that will be decided in the next few weeks.

Root writes a twice-weekly newsletter for Reason on legal issues, called Injustice System. Sign up for it here.
