A King, a Cold Drink, and the First Named Player
Historians place the game's origin in 12th-century northern France, where a ball was struck with the palm of the hand. The game was *jeu de paume*, literally "game of the palm", and it evolved into what is now called real tennis.
Louis X of France was a keen player and disliked playing outdoors, so around the end of the 13th century he had enclosed indoor courts built in Paris. The design spread to royal palaces across Europe.
His enthusiasm is also why we know his name in this context at all. In June 1316 at Vincennes, after a particularly exhausting game, Louis drank a large quantity of cooled wine and subsequently died of either pneumonia or pleurisy, though poisoning was also suspected. Because contemporary accounts recorded the circumstances, Louis X is history's first tennis player known by name. Charles V of France later had a court set up at the Louvre Palace, and Henry VIII of England was a serious fan.
The Name Is a Shout
The word tennis probably comes from the French *tenez*, an interjection meaning roughly "hold!", "receive!" or "take!". It was what the server called out to the opponent before putting the ball in play.
That detail says something about how different the early game was. It was played indoors, where the ball could be hit off the wall, making it closer to squash than to anything on a lawn. This indoor ancestor is what is now distinguished as real tennis, and it was popular in both England and France.
The surviving vocabulary is full of these fossils. "Deuce" and "love" both entered the game long before anyone thought of playing it on grass, and the calls persisted through a complete change of surface, equipment and social class. The sport that spread worldwide in the 19th century inherited the language of a medieval indoor court game played by kings.
The Sport That Came in a Box
Modern tennis has a surprisingly commercial origin. Between 1859 and 1865, solicitor Harry Gem and his friend Augurio Perera developed a game combining racquets and the Basque ball game pelota, playing it on Perera's croquet lawn in Birmingham. In 1872 they founded the world's first tennis club at Leamington Spa, the first time "lawn tennis" was used as a club activity name.
Then came the marketing. In December 1873, British army officer Walter Clopton Wingfield designed and patented a game he called *sphairistikè*, Greek for "ball-playing", soon shortened by players to "sticky". Crucially he sold it as a boxed set containing a net, poles, rackets, balls and, most importantly, his rules.
Wimbledon's museum curator credits him plainly: he was terrific at marketing, had good connections with the clergy, the legal profession and the aristocracy, and sent thousands of sets around the world within the first year or so. The oldest annual tournament ran at Leamington in 1874, three years before the All England Club held its first championships at Wimbledon in 1877.
Scoring Nobody Else Uses
Tennis keeps score in a manner the sport's own literature describes as peculiar to it. Points from zero to three are called "love", "15", "30" and "40". At three points each the score is not called 40 all but deuce, and a one-point lead after that is called advantage rather than a number.
The structure above that is equally particular. A game needs at least four points and a two-point margin. A set needs at least six games and a two-game margin, with a tiebreak at six games all producing a 7-6 set. Without a tiebreak, an advantage set simply continues without limit until someone leads by two.
What is remarkable is how little of this has moved. The rules of modern tennis have changed little since the 1890s, with only two real exceptions: until 1961 the server had to keep one foot on the ground at all times, and the tiebreak was adopted in the 1970s. Electronic review with a point challenge system arrived in 2006 and is increasingly giving way to fully automated line calling.
