Now...granted I dont have copies of slave holder journals but that sure does seem to indicate he wasnt the first to be owned by a black man (read that a few times for effect...slaves...owned by black men. Right here in America), but the first person declared to be a slave for life. Not an indentured servant...a slave for life. And his massa...well...now he was a black man wasnt he.
So we can play this all night or we can accept that blacks owned slaves throughout time. Whites owned slaves. America in its infancy had the benefit of learning from the growth achieved by other countries. Where slavery was enacted for 700 years in England, the importation of slaves was banned in America in 1808, a scant 20 years after the formation as a country. States had banned the practice before we became a country...yes...actions made by our 'founding fathers.' Its a shame that the lessons of humanity learned by most of the world by the 1800's still hasnt been learned where slavery is still practiced today. Old habits die hard, dont they.
