Who introduced slavery?

Slavery has existed in various forms throughout human history and predates recorded history, making it difficult to pinpoint a specific individual or group who "introduced" it. Ancient civilizations, such as those in Mesopotamia, Egypt, Greece, and Rome, practiced slavery, often as a result of warfare, economic needs, or social hierarchies. The systems and justifications for slavery evolved over time and varied significantly across cultures. Ultimately, slavery is a complex institution that arose independently in many societies around the world.
