The game that most people call tennis is the direct descendant of what is now known as real tennis or royal tennis (which continues to be played today as a separate sport with more complex rules). Most of the rules of the game commonly known as tennis derive from real or royal tennis. 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 ("game of the palm").[1] It was not until the 16th century that rackets came into use, and the game began to be called "tennis." It was popular in England and France and Henry VIII of England was a big fan of the game, now referred to as real tennis.[2]
