Badminton originated in ancient Greece and Egypt as a children's game called battledore and shuttlecock. It developed into its modern form in India in the 18th century under the name "Poona" and was introduced to England by British army officers. The game was formalized at the estate of the Duke of Beaufort in 1873 and took the name "Badminton" from his estate. Standardized rules were established in 1887 and an official governing body, the Badminton Association, was formed in 1895 to oversee the sport worldwide.
