William Archibald Dunning: William Archibald Dunning (12 May 1857–25 August 1922) was an American historian and political scientist at Columbia University noted for his work on the Reconstruction era of the United States.  He founded the informal Dunning School of interpreting the Reconstruction era through his own writings and the Ph.D. dissertations of his numerous students.  Historian Howard K. Beale was a leader of the "revisionist" school of the 1930s that broke with the Dunning interpretation.  Beale says the Dunning School broke new ground by escaping the political polemics of the day and used "meticulous and thorough research [...] in an effort to determine the truth rather than prove a thesis."  Beale states that, "The emphasis of the Dunning school was upon the harm done to the South by Radical Reconstruction and on the sordid political and economic motives behind Radicalism."  However, Dunning has also been criticized for his "blatant use of the discipline of history for reactionary ends" and for offering "scholarly legitimacy to the disenfranchisement of southern blacks and to the Jim Crow system."

Redeemers: In United States history, the Redeemers were a political coalition in the Southern United States during the Reconstruction Era that followed the Civil War.

They generally were led by the rich landowners, businessmen and professionals, and dominated Southern politics in most areas from the 1870s to 1910.

Johnny Lee (actor): John Dotson "Johnny" Lee, Jr. (July 4, 1898 – December 12, 1965) was an American singer, dancer and actor known for voicing the role of Br'er Rabbit in Disney's "Song of the South".

Reconstruction Era: The term Reconstruction Era, in the context of the history of the United States, has two senses: the first covers the complete history of the entire country from 1865 to 1877 following the American Civil War (1861 to 1865); the second sense focuses on the attempted transformation of the Southern United States from 1863 to 1877, as directed by Congress, with the reconstruction of state and society.  With the three Reconstruction Amendments, the era saw the first amendments to the U.S. Constitution in decades.
