Maryland was once a center of the slave trade: Maryland was one of the thirteen colonies that allowed slavery, and by the mid-18th century, it had become a major center of the domestic slave trade. Maryland slave traders sold enslaved people to plantation owners in other southern colonies and to the Caribbean.
