Why did the southern planters turn to African slaves as a labor source?

Southern planters turned to African slaves as a labor source because they needed a large and cheap workforce to work in the labor-intensive agricultural industry, particularly in tobacco, rice, and indigo cultivation. Slavery provided an efficient and profitable solution to their labor needs, as they could exploit enslaved laborers to increase their productivity and profits. Additionally, racial prejudices and the belief in the superiority of white people contributed to the acceptance of African slavery as a socially acceptable practice in the Antebellum South.
