Tea was first mentioned in English culture in 1597. In the 17th century, coffee houses in London began advertising tea as an amazing medicine. The 17th Duchess of Bedford popularized the tradition of afternoon tea among the upper classes in the 19th century. How tea was served showed social status, with "low tea" for royalty and "high tea" originally for workers. Tea gardens and tea houses grew in popularity in the 18th century as social spaces for drinking tea and entertainment. Afternoon tea is now becoming popular again in cities with varied tea menus.
