Hockey is a family of sports that involves maneuvering a ball or puck into the opponent's goal using a stick. Games involving curved sticks and projectiles date back 4000 years in Egypt, 1272 BC in Ireland, and 600 BC in Greece. In the Middle Ages, legislation was passed banning certain ball games like hockey. By the 19th century, various forms of historic games differentiated into the individual sports defined today like field hockey and ice hockey, with organizations forming to set rules and regulations and manage competition both domestically and internationally. There are several main types of hockey played today including field, ice, roller, sledge, and street hockey.
