Thaddeus Stevens (April 4, 1792 – August 11, 1868), of Pennsylvania, is a Republican leader and one of the most powerful members of the United States House of Representatives.
As chairman of the powerful House Ways and Means Committee, Stevens, a witty, sarcastic speaker and flamboyant party leader, dominates the House from 1861 until his death.
He writs much of the financial legislation that pays for the American Civil War.
Stevens and Senator Charles Sumner are the prime leaders of the Radical Republicans during the war and Reconstruction era.
Historians' views of Stevens have swung sharply since his death as interpretations of Reconstruction have changed.
The Dunning School (1890s-1940s) held Stevens responsible for demanding harsh treatment of the white South and violating American traditions of republicanism, depicting Stevens as a villain for his advocacy of harsh measures in the South.
This highly negative characterization held sway into the 1950s.
The rise of the neo-abolitionist school in the 1950s led to a greater appreciation of Stevens' work on civil rights for Freedmen.
A recent biographer characterizes him as, "The Great Commoner, savior of free public education in Pennsylvania, national Republican leader in the struggles against slavery in the United States and intrepid mainstay of the attempt to secure racial justice for the Freedmen during Reconstruction, the only member of the House of Representatives ever to have been known as the 'dictator' of Congress."
