92. THE HISTORY OF SUGAR 
Historically, sugarcane was not very important. It was simply a plant which people chewed to enjoy its 
sweetnesss. It was simply a plant which people chewed to enjoy its sweetness. That changed, however, when 
a method was developed in India for turning sugarcane juice into sugar crystals. In this form, sugar could be 
stored, carried, and sold around the world. In the 11th century, sugar was introduced to Western Europe by 
Crusaders who encountered it in Asia. The center of sugarcane production later moved from Asia to the 
Americas, following the arrival of European colonists. Sugarcane grew very well in the hot, humid 
environment of the Caribbean islands. Plants started to be cultivated on large sugarcane plantations there. Yet, 
before the 18th century, sugar was too expensive for most people to buy. In fact, it was sometimes called 
“white gold.” Around this time, however, it became possible to mass-produce sugar. As a result, the price 
dropped. In the 19th century, people started to think of sugar as a necessity. As more and more people 
developed a taste for sugar, demand for the product greatly increased. The sugar economy boomed, starting a 
period of major social change. Running a sugarcane plantation required a lot of workers. Plantation owners 
wanted the cheapest possible source of labor. Sadly, the slave trade grew bigger throughout the 16th, 17th, 
and 18th centuries as sugar became more popular. During the 18th century, almost a million people were 
taken from Africa to work on sugarcane plantations. People from East India and other parts of Asia were also 
brought to the Americas to work on the plantations. Global consumption of sugar continues to increase today. 
The sugar industry no longer uses slave labor, but many workers receive very little pay and live in poverty. 
For something so sweet, sugar has a bitter history.
