In the closing days of 1862, just three weeks before Emancipation, the administration of Abraham Lincoln commissioned a code setting forth the laws of war for US armies. It announced standards of conduct in wartime—concerning torture, prisoners of war, civilians, spies, and slaves—that shaped the course of the Civil War. By the twentieth century, Lincoln’s code would be incorporated into the Geneva Conventions and form the basis of a new international law of war.

In this deeply original book, John Fabian Witt tells the fascinating history of the laws of war and its eminent cast of characters—Washington, Jefferson, Franklin, Madison, and Lincoln—as they crafted the articles that would change the course of world history. Witt’s engrossing exploration of the dilemmas at the heart of the laws of war is a prehistory of our own era. Lincoln’s Code reveals that the heated controversies of twenty-first-century warfare have roots going back to the beginnings of American history. It is a compelling story of ideals under pressure and a landmark contribution to our understanding of the American experience.

Raves and Reviews

“Magnificent . . . Lincoln’s Code is both a celebratory chronicle of American lawmaking and a gruesome record of American wartime cruelty. . . . This monumental book, resting on colossal archival research and packed with memorable stories and arguments, is a major contribution to making sense of ours.”

– Gary J. Bass, The New York Times Book Review

"[W]ell-written and fascinating . . . . The value of Witt’s account is that it shows how the answer to [where we draw lines] has changed over the centuries—and how, whether in the Civil War or the War on Terror, our political leaders have struggled to reconcile the sometimes competing demands of humanitarianism and justice."

– Max Boot, Commentary Magazine

“[A] sweeping history of American engagement with the idea that the brutality of war should be constrained by humanitarian rules.”

– Jennifer Schuessler, The New York Times

"[A] significant work. . . . Witt establishes and supports a provocative case that the [law of war] reflects two competing, fundamental American ideals: humanitarianism and justice."

– Publishers Weekly

"Artfully mixing law, history, and sharp analysis, [Witt] examines the persistent struggle to reconcile justice and humanitarianism in America’s conduct of war... Truly remarkable, composed with all the precision and insight you expect from a law professor, marked by all the elegance and sparkling readability you don’t."

– Kirkus (starred review)

“A gripping narrative of the struggle to maintain the aspiration to honor, decency and common humanity amidst the brutal imperatives of war—from our war for independence, through the Civil War to the suppression of the insurrection in the Philippines. At the center John Witt places the first code for the conduct of war, promulgated by Lincoln during the darkest days of the Civil War: harsh, relentless, realistic, yet placing firm limits forbidding torture, the abuse of prisoners, treachery and purposeful harm to civilians. This book is an important addition to the ever-growing monument to our greatest and most complex national leader.”

– Charles Fried, author, with Gregory Fried, of Because It Is Wrong: Torture, Privacy and Presidential Power in the Age of Terror
