Indigo Boom in South Carolina: Enslaved Expertise Drives Colonial Economy While Credit Goes to Planter Class

Beginning around 1740 and reaching full commercial force by 1745, indigo cultivation became South Carolina's second most valuable export after rice, producing roughly one-third of the colony's total export value before the Revolutionary War. The commercial success is conventionally attributed to Eliza Lucas (later Pinckney), who at age 18 began experimenting with Caribbean indigo strains on her family's Wappoo Plantation outside Charleston. But the actual cultivation, harvest, and processing knowledge was held by enslaved workers — many of them from regions of West Africa where indigo had long been cultivated and used as dye. Enslaved people performed every labor-intensive step: planting, weeding, harvesting, steeping the plants in fermentation vats, beating the liquid to oxidize it, drawing off the water, pressing and drying the blue dye cakes. The toxic fermentation process exposed enslaved workers to noxious fumes. The indigo boom accelerated slave imports into South Carolina through the 1740s and 1750s.
