Widely considered the first history of US Constitutionalism that places African Americans at the center, Promises to Keep is a compelling overview of how conflict over African Americans' place in American society has shaped the Constitution, law, and our understanding of citizenship and rights. Both authoritative and accessible, this revised and expanded second edition incorporates key insights from the last three decades of scholarship and makes sense of recent developments in civil rights, from the War on Drugs to the rise of Black Lives Matter. Promises to Keep shows how African Americans have played a critical role in transforming the Constitution from a bulwark of slavery to a document that is truer to the nation's promise of equality. The book begins by examining debates about race from the Revolutionary Era at the Constitutional Convention and covers the establishment of civil rights protections during Reconstruction, the Jim Crow backlash, and the evolution of the civilrights movement, from the formation of the National Association for the Advancement for Colored People to legal victories and massive organized protests. Comprehensive in scope, this book moves from debates over slavery at the nation's founding to contemporary discussions of affirmative action, voting rights, mass incarceration, and police brutality. In the process, it provides readers with a historical perspective critical to understanding some of today's most important social and political issues.
