Real tennis – one of several games sometimes called "the sport of kings" – is the original racquet sport from which the modern game of lawn tennis (usually simply called tennis) is derived. It is also known as court tennis in the United States, formerly royal tennis in England and Australia,and courte-paume in France (a reference to the older, racquetless game of jeu de paume, the ancestor of modern handball and racquet games; many French real tennis courts are at jeu de paume clubs).
The term real was first used by journalists in the early 20th century as a retronym to distinguish the ancient game from modern lawn tennis (even though the latter sport is seldom contested on lawns these days outside the few social-club-managed estates such as Wimbledon).
Real tennis is still played on about 43 surviving courts in the United Kingdom, Australia, the United States and France. Despite a documented history of courts existing in the German states from the 17th century, the sport evidently died out there during or after the World War II reconstruction. The sport is supported and governed by various organizations around the world.
