Despite being considered one of the oldest team sports in the world, the origins of polo have been widely debated, with the earliest aspects of the game dating back thousands of years. While polo’s exact roots are unknown, it is interesting to observe how various cultures developed horseback ball games throughout history, which later evolved into the modern version of polo we know today.
In a fascinating article by Casper W. Whitney, published as a supplement to Harper's Weekly in 1891, he explores the development of polo in America, touching upon its rich history before the game arrived in the USA via England. Notably, he mentions a horseback ball game played by some Native American tribes during the 1700s and 1800s. He describes the game as "like shinny on horseback" (an informal type of hockey played on ice), with the Native players expertly using a short stick and riding with "a recklessness born of a set purpose to get possession of the ball, no matter what happens."
From Whitney's account, the Native American riders displayed remarkable horsemanship and combat skills, doing whatever it took to gain possession of the ball, including pulling one another from their horses. Whitney suggested that their form of "riding off" would be more appropriately called "riding down," as players often ended up on the ground and would sometimes be "badly damaged," but happy nonetheless. A sketch of Native players, drawn by Frederic Remington based on Whitney’s description of the game, provides insight into the speed, skill, power, brutality, and aggression of their version of the game. Notably, the riders used minimal tack, and no protective gear was required.
The game did not have a fixed number of players—sometimes there were four, sometimes eight—and it appeared to lack formal rules, as Whitney observed that "everything seemed permissible." He recorded these games being played in Dakota, Montana, and Wyoming in the late 1800s, but he did not witness them in the southern territories. However, he did observe ball games on horseback played by the Apache in Arizona.
