This book investigates the historical and legal foundations of systemic racism in the United States, questioning how judicial decisions and legislative actions institutionalized white supremacy. Peter Irons, a legal scholar and historian, utilizes a vast array of primary source documents, court records, and personal testimonies to trace the evolution of racial inequality. The work argues that the American legal system has historically functioned as a mechanism to enforce racial hierarchies rather than as a neutral arbiter of justice.

Legal scholars and historians frequently cite this work for its meticulous use of primary source evidence to expose the racial biases embedded in the American judiciary. Readers often note the academic density of the prose, which demands a high level of engagement with the historical legal record.
