In 1935, W. E. B. DuBois attacked the premises of the Dunning School in "Black Reconstruction", setting forth ideas such as the active agency of blacks in the era, that the struggle over control of black labor was central to the politics of the era, and that Reconstruction was a time of great promise and many accomplishments, the overthrow of which was a tragic defeat for democracy. While the work was largely ignored by historians at the time, later revisionist scholars lauded DuBois's analysis.
