Tennis originated from ancient ball games played in Egypt and spread to Europe in the 8th century through Moorish influence. Christian monks in Europe were the first to play an early form of tennis using their hands or sticks to hit a ball off walls. The game evolved over time to include wooden rackets and was popularized among French royals. Real tennis developed indoors in France and differed from the modern game by being played off walls and into court areas. Lawn tennis emerged in the 19th century as the game transitioned outside using vulcanized rubber balls on grass courts, aided by new tennis clubs and tournaments like the Wimbledon Championship. Today tennis is a global competitive sport enjoyed by millions worldwide.
