Henry Louis Gates, welcome back to FRESH AIR. Gates also hosts the PBS genealogical series "Finding Your Roots" and is a professor at Harvard, where he directs the Hutchins Center for African and African-American Research. The book is his companion to the new two-part PBS series he hosts, "Reconstruction: America After The Civil War," which airs April 9 and 16. Included in the book is a series of visual essays containing racist images of those periods - from ads, flyers, posters, playing cards, songbooks and more.

He also writes about the cultural and artistic Black Renaissance of the early 20th century. His new book is titled "Stony The Road: Reconstruction, White Supremacy And The Rise Of Jim Crow." It covers the period after the Civil War, when new amendments to the Constitution enshrined rights for African-Americans, and it covers the period that followed, known as Redemption, when white Southerners found ways to roll back those rights. The white nationalist movement of today has my guest, historian Henry Louis Gates, looking to the past for the roots of white supremacy.
