This book investigates the historical fracture between the woman suffrage and black suffrage movements during the Reconstruction era in the United States. Faye E. Dudden, a historian specializing in 19th-century American social and political movements, utilizes primary source documents and legislative records to analyze the strategic and ideological shift that occurred during the debate over the 15th Amendment. She argues that the alliance between these two causes collapsed due to political maneuvering and the emergence of exclusionary rhetoric, ultimately leading to a period of profound betrayal and political failure.

Historians and scholars of American political history frequently cite this work as a vital examination of the complexities and moral compromises inherent in the suffrage movement. Readers often note the academic rigor and the sobering nature of the narrative, which challenges simplified accounts of 19th-century reform efforts.
