English and Dutch settlers brought tea to the New World, where it was to play an important role in the history of the United States. The commodity was subject to a very high duty and, in 1773, the inhabitants of Boston decided to boycott its import. On the 16th December they threw the cargo of a vessel anchored in the harbour into the sea: it was this "Boston tea party" that provoked reprisals by the British authorities against the inhabitants of Massachusetts which, in turn, paved the way for the events that led to the War of Independence.

Tea was also the cause of more peaceful confrontations: like those of the " tea clippers ", light sailing ships used to transport tea. In the 19th century the huge demand intensified rivalry between ship-owners: great races took place along the main maritime routes of the East.

The Chinese were the sole producers at the time and imposed their rules: prohibitive prices, limited access to the port of Canton and a refusal to exchange tea for English textiles. To counter this commercial pressure the English decided to illegally introduce opium into China to create dependence - and therefore give them some bargaining power - on the part of their business partner. This was the start of the Opium Wars that would end with Britain annexing Hong Kong in 1842.

By the 19th century China could no longer cope with the ever-increasing western demand and in 1830 the English started to develop tea cultivation in other countries. Tea plantations were started in India in 1834 and in Ceylon in 1857. The Ceylonese plantations at first were purely experimental but, in 1869, after the total destruction of coffee plantations by a parasite, tea became the island's main source of income.

Tea was also planted in other Asian countries that have become important producers; also in ex-British colonies in Africa and, more recently, in Reunion Island and in Argentina.

Today, tea is the most drunk beverage in the world after water, we drink about 15,000 cups every second.
