In one form or another slavery has been reported from the very earliest historical records and there is substantial evidence of its existence among preliterate peoples too. There is a book with the approximate title THE WOMB OF IRON AND GOLD that recounts how extensively it developed in Africa prior to and independent of the Euro-American exploitation of African slaves.
