How did slavery get started?
Slavery began in the stone age. Sometimes tribes would raid each
other and take captives. As long as there has been recorded
history, there have been records of groups of people defeating
other groups at war and then taking the defeated people as slaves.
This went on in Africa, Australia, Asia, China, South America and
what we called the civilized world . . . Europe, from where it
moved to the "New World".
