Prior to the Seven Years' War (1756–63), the economy of Saint-Domingue gradually expanded, with sugar and, later, coffee becoming important export crops. After the war, which disrupted maritime commerce, the colony underwent rapid expansion. In 1767, it exported 72 million pounds of raw sugar and 51 million pounds of refined sugar, one million pounds of indigo, and two million pounds of cotton. Saint-Domingue became known as the "Pearl of the Antilles" – the richest colony in the 18th century French empire. By the 1780s, Saint-Domingue produced about 40 percent of all the sugar and 60 percent of all the coffee consumed in Europe. This single colony, roughly the size of Hawaii or Belgium, produced more sugar and coffee than all of Britain's West Indian colonies combined.
