San Domingo supplies half of the world's coffee, but imports decline after a slave revolt

French colonists started growing coffee in Haiti in the 18th century. At the time, sugarcane was harvested by slaves in the Caribbean, and when French colonists first grew coffee in San Domingo in the beginning of the 18th century, they required more African slaves to work on the plantations. By the last quarter of the 18th century, San Domingo was supplying half of the world's coffee. However, slaves who worked on the plantations lived in appalling conditions and were treated badly by their French masters. After a slave revolt in 1791 (which was successful), most plantations were burned, and despite later efforts to resuscitate coffee exports, Haiti never regained its dominance in the international trade market.
