I've been sleuthing around the net to find some of the earlier posts that I have seen here on FR.
IIRC the early black slave holders were from Africa. Not sure about the later ones.
Is much known about the black slave owners? Surely folks here on FR would know.
The first true slave owner in America was black. His name was Anthony Johnson, (1654), who was granted 250 acres in Northampton County; he convinced the court in Northampton that he was entitled to the lifetime services of John Casor, an indentured negro. This was the very first judicial approval of life servitude, ie slavery, except as punishment for a crime. Anthony Johnson was among one of the first groups of Africans brought to America.

Well,of course Africa had a long tradition of slavery but it was based on tribal conquest,not on the concept of one race being genetically inferior to the other.
I know that in Louisiana,there was a large mulatto class who often became slaveholders themselves.These mulatoes had pretty negative views of "pure"blacks.I lived in New Orleans in the Seventies and that attitude was very much alive even then.
