For most of its long history, tea was an almost exclusively Asian drink. According to Chinese tradition, the habit of brewing tea leaves dates back more than four thousand years, and for many centuries the plant grew only in China and a few neighbouring regions. Tea reached Europe in significant quantities only in the 1600s, when Dutch ships began carrying small chests of it alongside silks and spices.
In Britain the new drink spread with remarkable speed. By the middle of the eighteenth century, tea had moved from an expensive novelty in aristocratic drawing rooms to a daily habit in ordinary households. The government, eager to protect the profits of the East India Company, imposed heavy taxes on imported tea. These taxes contributed directly to one of the most famous protests in history: the Boston Tea Party of 1773, in which American colonists threw crates of tea into the harbour rather than pay the duty.
Growing demand in Europe soon outstripped supply from China. The British responded by smuggling tea plants and experienced workers out of China and establishing plantations in India, particularly in Assam and Darjeeling. These plantations changed the landscape and society of whole regions and tied vast areas of the colonial economy to a single crop.
Today tea is the most widely consumed drink in the world after plain water, and its cultivation supports millions of workers. Yet its history remains mixed. The same plant that gave rise to the polite ritual of afternoon tea also helped to spark revolutions, fund empires and remake distant lands - a reminder that even the simplest habits can carry unexpected weight.
