Reconstruction remains the most misunderstood period in American history, and Eric Foner's magisterial study transformed how scholars understand the twelve years following the Civil War. Where previous generations of historians portrayed Reconstruction as a tragic era of corruption and Black incapacity, Foner reveals it as a revolutionary experiment in interracial democracy that was violently overthrown. Drawing on unprecedented research in primary sources, he traces how four million newly freed people struggled to define their freedom while former Confederates worked to restore white supremacy through law and terror. Foner, a professor at Columbia University, examines the political transformations at federal, state, and local levels. The Fourteenth and Fifteenth Amendments established birthright citizenship and voting rights. Black men held office for the first time, from local constables to United States senators. Freedpeople built schools, churches, and families, refusing to work under conditions that resembled slavery. White Southerners responded with the Ku Klux Klan and similar organizations, murdering Republican leaders and intimidating Black voters until Northern will collapsed. The book explains why Reconstruction failed: a combination of white supremacist violence, Northern exhaustion, economic depression, and the triumph of a laissez-faire ideology hostile to federal intervention. The settlement of 1877 abandoned African Americans to a century of Jim Crow. Readers seeking to understand how promises of equality were betrayed, and why that betrayal still shapes American life, will find Foner's work indispensable.
