Giving voice to the voiceless, the Chicago Defender condemned Jim Crow, catalyzed the Great Migration, and focused the electoral power of black America. Robert S. Abbott founded the Defender in 1905, smuggled hundreds of thousands of copies into the most isolated communities in the segregated South, and was dubbed a "Modern Moses", becoming one of the first black millionaires in the process. His successor wielded the newspaper's clout to elect mayors and presidents, including Harry S. Truman and John F. Kennedy, who would have lost in 1960 if not for the Defender's support. Along the way, its pages were filled with columns by legends like Ida B. Wells, Langston Hughes, and Martin Luther King Jr.

Drawing on dozens of interviews and extensive archival research, Ethan Michaeli constructs a revelatory narrative of race in America from the age of Teddy Roosevelt to the age of Barack Obama, and brings to life the reporters who braved lynch mobs and policemen's clubs to do their jobs.
