The history of tea spreads across multiple cultures over the span of thousands of years. Tea originated in southwest China, likely the Yunnan region during the Shang dynasty as a medicinal drink. An early credible record of tea drinking dates to the 3rd century AD, in a medical text written by Hua Tuo. It first became known to western civilization through Portuguese priests and merchants in China during the early 16th century. Drinking tea became popular in Britain during the 17th century. The British introduced tea production, as well as tea consumption, to India, in order to compete with the Chinese monopoly on tea.

The Boston Tea Party was an American political and mercantile protest by the Sons of Liberty in Boston, Massachusetts, on December 16, 1773. The target was the Tea Act of May 10, 1773, which allowed the British East India Company to sell tea from China in American colonies without paying taxes apart from those imposed by the Townshend Acts. American Patriots strongly opposed the taxes in the Townshend Act as a violation of their rights. Protesters, some disguised as American Indians, destroyed an entire shipment of tea sent by the East India Company.

Gustav III of Sweden's coffee experiment was a twin study ordered by the king to study the health effects of coffee.

India is one of the largest tea producers in the world, although over 70 percent of its tea is consumed within India itself. A number of renowned teas, such as Assam and Darjeeling, also grow exclusively in India. The Indian tea industry has grown to own many global tea brands and has evolved into one of the most technologically equipped tea industries in the world. Tea production, certification, exportation, and all other facets of the tea trade in India are controlled by the Tea Board of India.
