Charles Sumner is mainly known as the abolitionist statesman who suffered a brutal caning on the Senate floor by the proslavery congressman Preston Brooks in 1856. This violent episode has obscured Sumner’s status as the most passionate champion of equal rights and multiracial democracy of his time. A friend of Alexis de Tocqueville, an ally of Frederick Douglass, and an adviser to Abraham Lincoln, Sumner helped the Union win the Civil War and pass into law the Emancipation Proclamation, the Thirteenth Amendment, the Freedmen’s Bureau, and the Civil Rights Act of 1875.

In his new book Charles Sumner: Conscience of a Nation, Zaakir Tameez presents Sumner as one of America’s forgotten founding fathers, a constitutional visionary who helped to rewrite the post–Civil War Constitution and give birth to modern civil rights law. He also argues that Sumner was a gay man who battled with love and heartbreak at a time when homosexuality wasn’t accepted. And he explores Sumner’s critical partnerships with the nation’s first generation of Black lawyers and civil rights leaders, whose legal contributions to Reconstruction have been overlooked for far too long.

Charles Sumner brings back to life one of America’s most inspiring statesmen, whose formidable ideas remain relevant to a nation still divided over questions of race, democracy, and constitutional law.
