Explain why the study of slavery is important ?

This is a question that deserves more space than we have here. Still, I'll try to articulate something. Slavery was and is one of the more shameful acts of humanity. The subjugation and torture of another human being, slavery, has been a blight on humanity for most of human existence. Studying it is important to enlighten people. Education can enlighten and change humanity. Make no mistake, slavery exists in some form all around the world today. Understanding its (slavery) history and psychology can change this insidious practice.
