Polo is a game in which players on horseback use long mallets to hit rolling balls. Polo is basically field hockey with horses.
Modern polo was developed by British military officers in colonial India during the 19th century, inspired by an ancient South Asian sport. Its nickname, "the sport of kings," reflects polo's reputation as a pastime for the wealthy. To play polo, you need a horse — also known as a polo pony — and to belong to a club where the game can be practiced and played competitively. The name polo comes from the Tibetan pulu, "ball."
