Don’t forget, slavery of black people in the new World satrted with a black man suing in court to enslave another black man. Slavery started in North America with blacks enslaving blacks, not whites enslaving blacks.
More exactly, the slavery of black people in the British North American mainland colonies started with a black man suing in court to keep another black man in slavery. The Spanish had held Africans in slavery in the New World for more than 100 years before Jamestown was founded. And Indians had practiced slavery for who knows how long (Cabeza de Vaca and his companions were slaves of a Texas Indian tribe for several years in the 1500s until they managed to escape).
