Slavery itself was not an institution that developed alone. It was an institution developed by humans, justified in moral issues and biblical beliefs that were enhanced by economic incentives. Slavery has been in existence for many centuries. The Romans used slaves to build their empires. Feudal lords used serfs to do their work.
