Google defines the term ‘Hockey’ to be “a team game played between two teams of eleven players each, using hooked sticks with which the players try to drive a small hard ball towards goals at opposite ends of a field. In North America, it is called field hockey to distinguish it from ice hockey.”
Hockey originated in England in the mid-18th century. This is primarily attributed to the growth of public schools, such as Eton. In 1876, the first Hockey Association was formed in the UK and laid down the first formal set of rules.
Incidentally, hockey is the national sport of India. Currently, the world’s best team of field hockey is Germany.
