In the 1950s, historians began to focus on the African-American experience as central to Reconstruction. They rejected completely any claim of black inferiority, which had marked many earlier historical works, and saw the developing civil rights movement as a second Reconstruction; some neoabolitionist writers stated they hoped their work on the postbellum era would advance the cause of civil rights. These authors sympathized with the Radical Republicans for their desire to help the African American, and saw Johnson as callous towards the freedman. In a number of works from 1956 onwards by such historians as Fawn Brodie, the former president was depicted as a successful saboteur of efforts to better the freedman's lot. These volumes included major biographies of Stevens and Stanton.[216] Reconstruction was increasingly seen as a noble effort to integrate the freed slaves into society.[210][215]
In the early 21st century, Johnson is among those commonly mentioned as the worst presidents in U.S. history.
