Eric Foner quotes
Arthur Schlesinger, Jr. challenged the underlying premise of prevailing Civil War scholarship. The South, he pointed out, had shown no evidence of a willingness to end slavery; indeed, over time it had become ever more hysterical in its defense. With one eye firmly on the recent past, Schlesinger insisted that a society closed in support of evil could not be appeased, and if it was worth a war to destroy Nazism, surely it was worth one to eradicate slavery. But not until the 1960s, under the impact of the civil rights revolution, did historians en masse repudiate a half-century of Civil War scholarship, concluding that the war resulted from an irreconcilable conflict between two fundamentally different societies, one resting on slavery, the other on free labor. Historians pushed Emancipation to the center of their account of the Civil War, and it has remained there ever since.

Andrew Johnson lacked Lincoln's qualities of greatness. While Lincoln had been open-minded, willing to listen to criticism, attuned to the currents of northern public opinion, and able to get along with all elements of his party, Johnson was stubborn, deeply racist, and insensitive to the opinions of others. If anyone was responsible for the wreck of his presidency, it was Johnson himself, first by establishing new governments in the South in which blacks had no voice whatsoever, and then refusing, when these governments sought to reduce freedpeople to a situation akin to slavery through the Black Codes, to heed the rising tide of northern concern. As congressional opposition mounted, Johnson refused to budge.
