Answer: E - The Radical Republicans did not support the Black Codes, which were a form of institutionalized racial prejudice. The Black Codes were passed in Southern states in response to the abolition of slavery and the Confederacy's defeat in the Civil War. They sought to relegate freedmen to social and legal statuses less than that of white citizens, effectively maintaining the same socio-cultural distinctions that were in place when slavery was still legal. The Black Codes were similar to (but not the same as) the Jim Crow laws, which were not enacted until the end of the 19th century.
