Born to former enslaved people in Alabama in 1883, Mitchell studied with Booker T. Washington at Tuskegee Institute and later moved to Washington DC and became a lawyer. He continued his career in Chicago, where the Great Migration had helped transform the city's South Side into a vibrant, multiracial enclave.
As a congressman, Mitchell helped to create an enduring alliance between Black Americans and the Democratic party. Seeing his primary role as representing the South's disempowered Black population, his belief that solutions to the region's racial problems should arise from a new cadre of locally trained leaders brought him into frequent, vituperative conflict with the NAACP, the Republican Party, and the Black press. The first Black lawyer to argue successfully before the Supreme Court, his unanimous victory in Mitchell v. United States would have long-term consequences for the Civil Rights Movement.
A Carpetbagger in Reverse is the first publication significantly based on Mitchell's papers, an essential and often overlooked source of insights about the development of Black political and culture life in the 1930s and 1940s.
