The racket sport traditionally named lawn tennis, invented in Edgbaston, Warwickshire, England, now commonly known simply as tennis, is the direct descendant of what is now denoted real tennis or royal tennis, which continues to be played today as a separate sport with more complex rules. Most rules of (lawn) tennis derive from this precursor and it is reasonable to see both sports as variations of the same game. Most historians believe that tennis originated in the monastic cloisters in northern France in the 12th century, but the ball was then struck with the palm of the hand, hence the name jeu de paume. It was not until the 16th century that rackets came into use and the game began to be called 'tennis'. It was popular in the Kingdom of France as well as in England, where Henry VIII of England was a notable enthusiast of the game, which is now referred to as 'real tennis'. Many original tennis courts remain, including courts at Oxford, Cambridge, Falkland Palace in Fife where Mary Queen of Scots regularly played, and Hampton Court Palace. Many of the French courts were decommissioned with the terror that accompanied the French Revolution. The Tennis Court Oath was a pivotal event during the first days of the French Revolution; it was a pledge signed by 576 of the 577 members from the Third Estate who were locked out of a meeting of the Estates-General on 20 June 1789. Marylebone Cricket Club's Rules of Lawn Tennis have been official, with periodic slight modifications, ever since 1875. Those rules were adopted by the All England Lawn Tennis and Croquet Club for the first lawn tennis championship, The Championships, Wimbledon in 1877. The Davis Cup, an annual competition between men's national teams, dates to 1900. The analogous competition for women's national teams, the Fed Cup, was founded as the Federation Cup in 1963 to celebrate the 50th anniversary of the founding of the International Tennis Federation, also known as the ITF. Promoter C. C. Pyle created the first professional tennis tour in 1926, with a group of American and French tennis players playing exhibition matches to paying audiences. The most notable of these early professionals were the American Vinnie Richards and the Frenchwoman Suzanne Lenglen. Players turning pro could not compete in the major (amateur) tournaments. In 1968 commercial pressures and rumours of some amateurs taking money under the table led to the abandonment of this distinction, inaugurating the Open Era, in which all players could compete in all tournaments and top players were able to make their living from tennis. With the beginning of the Open Era, the establishment of an international professional tennis circuit, and revenues from the sale of television rights, tennis's popularity has spread worldwide, and the sport has shed its upper/middle-class English-speaking image.
