The Province of Carolina was the first attempted English settlement south of Virginia. It was a private venture, financed by a group of English Lords Proprietors who obtained a Royal Charter to the Carolinas in 1663, hoping that a new colony in the south would become profitable like Jamestown. Carolina was not settled until 1670, and even then the first attempt failed because there was no incentive for emigration to that area. Eventually, however, the Lords combined their remaining capital and financed a settlement mission to the area led by Sir John Colleton. The expedition located fertile and defensible ground at what became Charleston, originally Charles Town for Charles II of England. The original settlers in South Carolina established a lucrative trade in food for the slave plantations in the Caribbean. The settlers came mainly from the English colony of Barbados and brought African slaves with them. Barbados was a wealthy sugarcane plantation island, one of the early English colonies to use large numbers of Africans in plantation-style agriculture. The cultivation of rice was introduced during the 1690s and became an important export crop.
