India is considered the cradle of modern polo. Babar, the founder of the Mughal dynasty in the 15th century, firmly established its popularity. The period between the decline of the Mughal dynasty and the upsurgence of the British Imperial rule, polo almost vanished from the mainland India.
Now coming to the question, i.e. State of Manipur is the birth place of modern Polo game. It is also home to the oldest active polo ground, Mapal Kangjeibung. Before British influence, sagol kangjei, as polo was originally called here, was played with seven players per team. The mallets were made of cane, and the ball was made from bamboo root. The name polo came later: The Tibetan word for bamboo root is “pulu.” Today, Manipur follows International Polo Association rules, and teams consist of four players. Sagol kangjei is played only as an exhibition sport at tournaments and festivals.
