The Origins of the Polo Sport
Mounted nomads in Central Asia played a version of polo that was part sport and part training for war, with as many as 100 men on a side. The game followed the nomads’ migration to Persia (modern Iran) some time between 600 B.C. and 100 A.D.
In Persia, polo became a national sport, played by the nobility and military men. The game was formalized and spread west to Constantinople, east to Tibet, China and Japan, and south to India.
