This heirloom grain, together with the skilled knowledge and forced labor of West Africans and their descendants, made South Carolina very, very rich. From 1720 to the outbreak of the Civil War, rice was the most economically valuable crop for this state. White landowners, who thought rice would do well in the low country, themselves lacked practical knowledge of rice cultivation. Instead, they paid a premium to slave traders to capture and transport laborers from the well-established rice region of West Africa to Carolina. During the 18th century, many enslaved people brought into Charleston came from this rice-growing area. These people and their descendants created the Gullah-Geechee culture in the low country.
