Kabaddi originated in ancient times in India and the modern game developed in the 1930s. The first codified rules were established in 1921. Kabaddi became organized at the national level in India in the 1950s with the All India Kabaddi Federation. It has since grown tremendously in popularity and become an international sport with the formation of the International Kabaddi Federation in 2004. India has dominated internationally by winning gold medals at every Asian Games since 1990 and the first World Cup in 2004. The professional Pro Kabaddi League was established in 2014 in India, further popularizing the sport around the world.
