In Abraham Lincoln and Treason in the Civil War, Jonathan White reveals how the arrest and prosecution of this little-known Baltimore farmer had a lasting impact on the Lincoln administration and Congress as they struggled to develop policies to deal with both northern traitors and southern rebels. His work sheds significant new light on several perennially controversial legal and constitutional issues in American history, including the nature and extent of presidential war powers, the development of national policies for dealing with disloyalty and treason, and the protection of civil liberties in wartime.

Jonathan W. White is an assistant professor of American Studies and a fellow at the Center for American Studies at Christopher Newport University.
