Both Lincoln and Johnson had foreseen that the Congress would have the right to deny Southern legislators seats in the U.S. Senate or House of Representatives, under the Constitution. This came to pass when, under the leadership of Thaddeus Stevens, those congressmen, also known as radical republicans, who sought to punish the South refused to seat its elected senators and representatives.

It was named after Columbia University professor William Dunning, whose seminar trained many of the leading historians. In a series of state-by-state monographs, as well as large-scale histories, Dunning School historians argued that Reconstruction was badly handled after the Radical Republicans won the 1866 elections. They generally agreed with the policies of Abraham Lincoln and especially Andrew Johnson, and sharply condemned Ulysses Grant as corrupt.
