Slavery started in the colonies due to the high labor demands. Specifically in the South, they grew tobacco, cotton, and rice, which all require hard outdoor labor. The Europeans didn’t want to do all the labor, which led to them acquiring slaves. Slavery was viewed as beneficial to them since the slaves weren’t working for money and some slave owners believed that the slaves lived a much better life in America than they would be living if they had stayed in Africa.
