James M. McPherson, George Henry Davis 1886 Professor of American History, Emeritus, Princeton University, author of Tried by War: Abraham Lincoln as Commander in Chief:
The Civil War ushered in the first constitutional definition of U.S. citizenship. In a thorough and systematic study of this development, Christian G. Samito shows how African American and Irish American soldiers helped earn equal citizenship for their people by fighting for the Union. Becoming American under Fire is essential reading for an understanding of this important transformation in the American polity.
Heather Cox Richardson, University of Massachusetts Amherst, author of West from Appomattox: Soldiers, Slavery, and the Civil War:
In this important book, Christian G. Samito explains how ex-slaves and Irish immigrants helped to create a new definition of American citizenship. Their experiences in military service, determination to vote, and fervent loyalty to the federal government changed Americans' hazy antebellum concept of citizenship as loyalty to a state into a clear set of rights and duties in a newly powerful nation. This dramatic change defined America in the late nineteenth century, and its repercussions echo today.
Christopher Waldrep, Jamie and Phyllis Pasker Professor of History, San Francisco State University, author of Roots of Disorder and The Many Faces of Judge Lynch:
Historians are increasingly recognizing the importance of citizenship as a concept, and Christian G. Samito wisely takes a bottom-up approach, recognizing the agency of those displaced groups agitating for inclusion. Becoming American under Fire is a very good book on an important and timely topic.
Christian Samito's Becoming American Under Fire is a superb study of the expansion of citizenship during the Civil War era. He proves that through active defense of the Union, the Irish and African Americans in the North gained the skills and confidence to demand their place in the American social and political arenas. While the expansion of citizenship affected all Americans, few groups made such a dramatic transition from antebellum nativism and slavery to the legal changes that followed the war as did Irish Catholics and blacks. Because of this, they serve as an excellent lens through which to study this process.
Chandra Manning, Georgetown University, author of What This Cruel War Was Over: Soldiers, Slavery, and the Civil War:
Christian G. Samito's thoughtful examination reveals how African Americans' and Irish Americans' ideas and actions in wartime contributed to a notion of citizenship grounded in loyalty and consent, not race or place of birth. We have long known that the Civil War 'nationalized' American citizenship. Thanks to Samito, we now know much more about precisely how that happened and what it meant.
Kerby A. Miller, Curators Professor of History, University of Missouri, author of Emigrants and Exiles: Ireland and the Irish Exodus to North America:
Christian G. Samito's Becoming American under Fire is an important book that clarifies the debt that all Americans today owe to the ex-slaves and Irish immigrants who lived in the United States after the Civil War. Although at the time African Americans were unable to achieve real equality, and also Irish Americans were unsuccessful in liberating Ireland from British rule, in the process of struggling to achieve their goals both groups played major roles—sometimes even in cooperation with each other—in expanding the meanings and protections of citizenship for all Americans.
Lawrence F. Kohl, University of Alabama, author of The Politics of Individualism:
Becoming American under Fire makes an important contribution to the history of American citizenship. Christian G. Samito demonstrates that the Civil War military service of Irish and African Americans led them to make demands for full inclusion and it created a moral indebtedness on the part of the native-born white population that made opposing those demands difficult. No other book illuminates this subject as well as this one does. No one else has related the progress of this development so well to the experience of the Civil War.
Samito argues that the United States underwent a 'crisis of citizenship' in the 1850s as local allegiances combined with rigid racism to produce a mélange of conflicting definitions of who was and was not an 'American.'... Thoroughly researched and elegantly written, this important work will be profitably read by students of nationalism and the Civil War era. Highly recommended.
Wolfgang Hochbruck:
One of the main positive and original assets of Samito's intelligently written and highly readable book is the fact that he combines the role and situation of Africamericans and Irish in relation to their being and becoming 'American’.... Samito’s book adds significantly to our understanding of the Irish as well as the Africamerican experience of the Civil War, and should be on the required reading list whenever the issue of ethnicity is raised in connection with the Union side in the Civil War.
In this well-crafted, thoughtfully prepared book, Samito does a nice job of blending the Civil War experiences of African Americans and Irish Americans to draw his conclusions and to explore what it means to be an American, not only in the nineteenth century but in the twenty-first century as well. Anyone interested in Civil War history, American political history, or the American experience in general would do well to take a look at this work.
By focusing on the importance of citizenship, Samito offers an important addition to scholarship on the Civil War era.... This is an outstanding book. It offers a terrific bottom-up approach to citizenship debates in the Civil War era and demonstrates the powerful role played by Irish American and African American men in creating new forms of American citizenship and nationalism in the mid-nineteenth century. It would be extremely useful in any course on the Civil War.
