When her father, George Lucas, was called to military duty in Antigua in the West Indies in 1739, Eliza Lucas remained to manage his three plantations in South Carolina. After three years of experimentation with ginger, cotton, indigo, and alfalfa, she succeeded in marketing the first crop of indigo. Parliament then subsidized the plant, and by 1754 South Carolina was exporting more than 1,000,000 pounds (454,000 kg) of the crop annually. In 1744 she married Charles Pinckney, Carolina's first native lawyer, and on his Charleston plantation she revived the cultivation of silkworms and manufacture of silk. When her husband died in 1758, Eliza again became a plantation manager, guiding her family's extensive landholdings. Her sons Charles Cotesworth and Thomas became diplomats.
