In the years following the Civil War known as Reconstruction, newly-freed African American men could finally vote, and would be elected to represent Southerners in Congress.

Yet, Reconstruction is now being given its due in school curriculums, and in a new PBS documentary by Harvard professor Henry Louis Gates. Mo Rocca talks with Gates, as well as with historian Eric Foner and author Lawrence Otis Graham, about some of the most noted African American figures in the post-Civil War era.
