What are the motifs in The Strange Career of Jim Crow by C. Vann Woodward?

Black status is a recurring idea. Slavery was only one means by which the white man defined the position of blacks in his society. From the first contact between the races, as Africa was explored and conquered by Europeans, the assumption of Anglo-Saxon superiority was clear and fully promulgated. Even outside the realm of slavery, the Negro was to be used, abused, and exploited, permitting injustices and brutality, and relegating blacks to a clearly subordinate position. For these reasons, Apartheid was established in South Africa, and slavery became an appropriate economic solution for white planters in the West Indies and Southern colonies.
