Badminton originated in the mid-18th century in British India where British officers added a net to the game of battledore and shuttlecock. It developed further after being brought back to England where formal rules were established. Badminton is played by two or four players on a marked court with a net, using lightweight rackets to hit a cork shuttlecock back and forth. Key shots in badminton include serves, clears, drops shots, drives, smashes, and net shots which are used to outmaneuver opponents around the court.
