It is believed Black Tea first emerged in the 1700s, in China´s Wuyi Mountains in the northern Fujian province. By the 1830s, the British were importing large quantities of Tea from China, causing them cash shortages. In order to reduce the costs, the British attempted to start their own plantations in their colonies. By the 1850s, the British had succeeded and plantations in the Darjeeling region and Assam province in India were flourishing.
Later, in the 1870s, Tea was taken to Sri Lanka, previously known as Ceylon, and a new Tea was also created.
