“Negro rule under unscrupulous adventurers had been finally put an end to in the South, and the natural, inevitable ascendancy of the whites, the responsible class, established.”

1960s, How Long, Not Long (1965)
Context: If it may be said of the slavery era that the white man took the world and gave the Negro Jesus, then it may be said of the Reconstruction era that the southern aristocracy took the world and gave the poor white man Jim Crow. He gave him Jim Crow. And when his wrinkled stomach cried out for the food that his empty pockets could not provide, he ate Jim Crow, a psychological bird that told him that no matter how bad off he was, at least he was a white man, better than the black man. And he ate Jim Crow. And when his undernourished children cried out for the necessities that his low wages could not provide, he showed them the Jim Crow signs on the buses and in the stores, on the streets and in the public buildings. And his children, too, learned to feed upon Jim Crow, their last outpost of psychological oblivion. Thus, the threat of the free exercise of the ballot by the Negro and the white masses alike resulted in the establishment of a segregated society. They segregated southern money from the poor whites; they segregated southern mores from the rich whites; they segregated southern churches from Christianity; they segregated southern minds from honest thinking; and they segregated the Negro from everything. That’s what happened when the Negro and white masses of the South threatened to unite and build a great society: a society of justice where none would pray upon the weakness of others; a society of plenty where greed and poverty would be done away; a society of brotherhood where every man would respect the dignity and worth of human personality.

1860s, The Constitution of the United States: Is It Pro-Slavery or Anti-Slavery? (1860)
Context: The Constitution itself. Its language is "we the people"; not we the white people. Not even we the citizens, not we the privileged class, not we the high, not we the low, but we the people. Not we the horses, sheep, and swine, and wheel-barrows, but we the people, we the human inhabitants. If Negroes are people, they are included in the benefits for which the Constitution of America was ordained and established. But how dare any man who pretends to be a friend to the Negro thus gratuitously concede away what the Negro has a right to claim under the Constitution? Why should such friends invent new arguments to increase the hopelessness of his bondage? This, I undertake to say, as the conclusion of the whole matter, that the constitutionality of slavery can be made out only by disregarding the plain and common-sense reading of the Constitution itself; by discrediting and casting away as worthless the most beneficent rules of legal interpretation; by ruling the Negro outside of these beneficent rules; by claiming that the Constitution does not mean what it says, and that it says what it does not mean; by disregarding the written Constitution, and interpreting it in the light of a secret understanding. It is in this mean, contemptible, and underhand method that the American Constitution is pressed into the service of slavery. They go everywhere else for proof that the Constitution declares that no person shall be deprived of life, liberty, or property without due process of law; it secures to every man the right of trial by jury, the privilege of the writ of habeas corpus — the great writ that put an end to slavery and slave-hunting in England — and it secures to every State a republican form of government. Anyone of these provisions in the hands of abolition statesmen, and backed up by a right moral sentiment, would put an end to slavery in America.
