The Broken Constitution: Lincoln, Slavery, and the Refounding of America (2021) “seeks to retell the story of the meaning of the Constitution in the Civil War and of Lincoln’s decisive action not as the story of successful salvation but as something more dramatic, and more extreme: the frank breaking and frank remaking of the entire union of order, rights, constitution, and liberty.” The book is a history of “an extraordinary transformation” in Lincoln's “beliefs about the meaning of the Constitution.”
