This book focuses on the post-Civil War treason prosecution of Confederate President Jefferson Davis, which was seen as a test case on the major question that animated the Civil War: the constitutionality of secession. The case never went to trial because it threatened to undercut the meaning and significance of Union victory. Cynthia Nicoletti describes the interactions of the lawyers who worked on both sides of the Davis case - who saw its potential to disrupt the verdict of the battlefield against secession. In the aftermath of the Civil War, Americans engaged in a wide-ranging debate over the legitimacy and effectiveness of war as a method of legal adjudication. Instead of risking the 'wrong' outcome in the highly volatile Davis case, the Supreme Court took the opportunity to pronounce secession unconstitutional in Texas v. White (1869).

'The genius of Nicoletti’s work is that the Davis case provides a window into the persistent belief in American minds (even in the North) that secession was possible. That belief made the trial and execution of Davis that much more problematic than scholars have seen. Nicoletti backs up these claims with unsurpassed knowledge of legal proceedings and impressive research.'

'Cynthia Nicoletti tackles a hugely important topic: the post-Civil War resolution of the legal status of the Confederacy. The prosecution of Jefferson Davis squarely posed the question whether the Confederacy had become a separate country by seceding. If it had, southerners insisted there could be no treason. If it had not, many of the war powers asserted by the North would be called into question. Nicoletti brilliantly tracks the efforts of jurists and politicians to work through momentous questions about the American constitutional order.'

'Nicoletti’s beautifully written book studies a crucially important trial that never happened. She situates Davis’s treason case in the wider context of public discussions about how to treat officials of the former Confederacy and what to do about secession. Law, as Nicoletti argues, was not separate from other aspects of life in this period; it was deeply implicated within them and, thus, inseparable from them.'

'Using the proposed but abandoned trial of Confederate President Jefferson Davis after the Civil War as backdrop, this book explores the historical and legal complexities of that conflict, specifically asking whether the Confederate states actually left the US. … An outstanding book for collections on American history, the Civil War, and constitutional law. Highly Recommended.'

‘Secession on Trial stands as a deeply informative, thoroughly researched, and groundbreaking work about the ideological and factual context of the Davis trial. Nicoletti set herself a very difficult project and succeeds in creating a narrative told through a range of voices that questions what has become the Davis trial’s standard narrative of Radical Republican consensus. Readers with an interest in legal history, debates about the nature of treason, and memorialization of the US Civil War will greatly appreciate her efforts.’
