In Abraham Lincoln and a New Birth of Freedom, Howard Jones explores the relationship between President Lincoln’s wartime diplomacy and his interrelated goals of forming a more perfect Union and abolishing slavery. From the outset of the Civil War, Lincoln’s central purpose was to save the Union by defeating the South on the battlefield. No less important was his need to prevent a European intervention that would have facilitated the South’s move for independence. Lincoln’s goal of preserving the Union, however, soon evolved into an effort to form a more perfect Union, one that rested on the natural rights principles of the Declaration of Independence and thus necessitated emancipation. Howard Jones is University Research Professor in the Department of History at the University of Alabama. He is the author of numerous books, including Mutiny on the Amistad: The Saga of a Slave Revolt and Its Impact on American Abolition, Law, and Diplomacy which provided the historical basis for the movie Amistad.
