    In the late 18th century, the English East India Company was buying tea and silk
    from China for sale in England. Tea became a popular drink and by 1830, 30 million pounds tea was being imported into England. The tea could be bought only by paying in silver coins or bullion because the Manchus rulers of China were unwilling to allow the entry of foreign goods. Merchants, therefore, looked for ways to stop the loss of silver. They searched for a commodity they could sell in China, something they could persuade the Chinese to buy. And that commodity was opium which was introduced by the Portuguese into China. While the English cultivated a
