The restriction to amateurs in club and tournament operations, which had come under increasing criticism in the decades after the Second World War, was largely abolished in 1968. In 1923 the International Tennis Association, founded ten years earlier, agreed on the four most important Grand Slam tournaments to date. In 1900, the Davis Cup, the first international tennis competition, took place.

Tennis tournaments with international participation were already being held in Europe at the turn of the century. In the 1870s, modern lawn tennis was invented in Great Britain, which first spread to Europe, the USA and the colonies of the British Empire. It was played outdoors by the common people, from which other games such as pelota have emerged over time. Jeu de Paume developed from an early setback game that was widespread among monks and flourished in the ballrooms of the 16th and 17th centuries, especially in France and England, and was popular with the nobility and bourgeoisie. The forerunner of tennis in France was first reported in 1325. It can be traced back to French monasteries in the Middle Ages. The history of tennis includes the development of the sport of tennis from the High Middle Ages to the present day.
