[N]either the Civil War nor Reconstruction fit neatly into traditional Marxist frameworks. Both the Civil War and Reconstruction belong to a chapter … - Allen C. Guelzo

[W]hat Reconstruction succeeded in doing: it helped us avoid a renewed outbreak of civil war (which, considering the history of civil conflicts, is no small achievement); it laid the legal and constitutional foundations for a more egalitarian America, foundations that it took only sixty-five years to revitalize into the Civil Rights Movement; it restored the original balance of constitutional federalism, putting aside the states’ rights absolutism of the pre-war Southern aristocracy. But I do not say this to encourage any historical Pollyannaism about Reconstruction. That restored federal balance permitted the emergence of the first women’s voting rights legislation, the curtailing of municipal corruption, and the introduction of widespread public schooling; it also permitted the emergence of Jim Crow. But as Lincoln said, “this is a world of compensation.” The historical good and the evil, even in Reconstruction, do not come unmixed.

[A]bsent Lincoln's proclamation, not a single fugitive slave would ever be other than a fugitive, rather than a legally free man.

Reconstruction was overthrown, not that it ground to an exhausted halt. Indifference and inattention helped to divert resources from Reconstruction, but the real dagger was planted in Reconstruction’s back by political insurgency.
