Final answer:
British planters from Barbados were among the original settlers of South Carolina, establishing Charleston in 1670 and bringing the plantation system and slavery with them.
Step-by-step explanation:
A large number of South Carolina's original settlers were British planters from Barbados. In the late 17th century, opportunities for land acquisition in Barbados were dwindling, leading these planters to relocate to the new Carolina colony. They established Charles Town, known today as Charleston, in 1670, bringing with them extensive experience in colony building and an established system of plantation slavery that had thrived in Barbados.
