Alexander H. Stephens said this quote

Many governments have been founded upon the principle of the subordination and serfdom of certain classes of the same race; such were and are in violation of the laws of nature. Our system commits no such violation of nature’s laws. With us, all of the white race, however high or low, rich or poor, are equal in the eye of the law. Not so with the negro. Subordination is his place. He, by nature, or by the curse against Canaan, is fitted for that condition which he occupies in our system. The architect, in the construction of buildings, lays the foundation with the proper material-the granite; then comes the brick or the marble. The substratum of our society is made of the material fitted by nature for it, and by experience we know that it is best, not only for the superior, but for the inferior race, that it should be so. It is, indeed, in conformity with the ordinance of the Creator. It is not for us to inquire into the wisdom of His ordinances, or to question them.
