The sugar was then shipped back to Europe. For the slave laborer, the routine started all over again. With the 19th-century abolition of slavery, plantations continued to grow sugar cane, but sugar beets, which can be grown in temperate climates, increased their share of the sugar market. Indigofera was a major crop cultivated during the 18th century, in Venezuela, Guatemala—and Haiti until the slave rebellion against France that left them embargoed by Europe and India in the 19th and 20th centuries.

Mahatma Gandhi's investigation of indigo workers' claims of exploitation led to the passage of the Champaran Agrarian Bill in 1917 by the British colonial government. The currency for the Georgia colony was the Pound sterling, a gold coin or very light green bill with the national pound symbol. The currency is worth about one and one half U.S. dollar.
