Hockey is a term used to denote a family of various types of both summer and winter team sports which originated on either an outdoor field, sheet of ice, or dry floor such as in a gymnasium. While these sports vary in specific rules, numbers of players, apparel, and playing surface, they share broad characteristics of two opposing teams using a stick to propel a ball or disk into a goal.
There are many types of hockey. Some games make the use of skates, either wheeled or bladed, while others do not. In order to help make the distinction between these various games, the word hockey is often preceded by another word i.e. field hockey, ice hockey, roller hockey, rink hockey, or floor hockey.
In each of these sports, two teams play against each other by trying to manoeuvre the object of play, either a type of ball or a disk (such as a puck), into the opponent's goal using a hockey stick. Two notable exceptions use a straight stick and an open disk (still referred to as a puck) with a hole in the center instead. The first case is a style of floor hockey whose rules were codified in 1936 during the Great Depression by Canada's Sam Jacks. The second case involves a variant which was later modified in roughly the 1970s to make a related game that would be considered suitable for inclusion as a team sport in the newly emerging Special Olympics. The floor game of gym ringette, though related to floor hockey, is not a true variant due to the fact that it was designed in the 1990s and modelled off of the Canadian ice skating team sport of ringette, which was invented in Canada in 1963. Ringette was also invented by Sam Jacks, the same Canadian who codified the rules for the open disk style of floor hockey 1936.
Certain sports which share general characteristics with the forms of hockey, but are not generally referred to as hockey include lacrosse, hurling, camogie, and shinty.
The first recorded use of the word hockey is in the 1773 book Juvenile Sports and Pastimes, to Which Are Prefixed, Memoirs of the Author: Including a New Mode of Infant Education by Richard Johnson (Pseud. Master Michel Angelo), whose chapter XI was titled "New Improvements on the Game of Hockey". The belief that hockey was mentioned in a 1363 proclamation by King Edward III of England is based on modern translations of the proclamation, which was originally in Latin and explicitly forbade the games "Pilam Manualem, Pedivam, & Bacularem: & ad Canibucam & Gallorum Pugnam". The English historian and biographer John Strype did not use the word "hockey" when he translated the proclamation in 1720, instead translating "Canibucam" as "Cambuck"; this may have referred to either an early form of hockey or a game more similar to golf or croquet.
The word hockey itself is of unknown origin. One supposition is that it is a derivative of hoquet, a Middle French word for a shepherd's stave. The curved, or "hooked" ends of the sticks used for hockey would indeed have resembled these staves, and similar folk etymologies exist for the bat-and-ball sports of Croquet and Cricket. Another supposition derives from the known use of cork bungs (stoppers), in place of wooden balls to play the game. The stoppers came from barrels containing "hock" ale, also called "hocky".
In most of the world, the term hockey when used without clarification refers to field hockey, while in Canada, the United States, Russia and most of Eastern and Northern Europe, the term usually refers to ice hockey.
In more recent history, the word "hockey" is used in reference to either the summer Olympic sport of field hockey, which is a stick and ball game, and the winter ice team skating sports of bandy and ice hockey. This is due to the fact that field hockey and other stick and ball sports and their related variants preceded games which would eventually be played on ice with ice skates, namely bandy and ice hockey, as well as sports involving dry floors such as roller hockey and floor hockey. However, the "hockey" referred to in common parlance often depends on locale, geography, and the size and popularity of the sport involved. For example, in Europe, "hockey" more typically refers to field hockey, whereas in Canada, it typically refers to ice hockey. In the case of bandy, the game was initially called "hockey on the ice" and preceded the organization and development of ice hockey, but was officially changed to "bandy" in the early 20th century in order to avoid confusion with ice hockey, a separate sport. Bandy, while related to other hockey games, derives some of its inspiration from Association football.
Sledge hockey, a variant of ice hockey designed for players with physical disabilities, was created in the 1960s and has since been renamed, "Para-ice hockey".
Games played with curved sticks and a ball can be found in the histories of many cultures. In Egypt, 4000-year-old carvings feature teams with sticks and a projectile, hurling dates to before 1272 BC in Ireland, and there is a depiction from approximately 600 BC in Ancient Greece, where the game may have been called kerētízein (κερητίζειν) because it was played with a horn or horn-like stick (kéras, κέρας). In Inner Mongolia, the Daur people have been playing beikou, a game similar to modern field hockey, for about 1,000 years.
Most evidence of hockey-like games during the Middle Ages is found in legislation concerning sports and games. The Galway Statute enacted in Ireland in 1527 banned certain types of ball games, including games using "hooked" (written "hockie", similar to "hooky") sticks.
...at no tyme to use ne occupye the horlinge of the litill balle with hockie stickes or staves, nor use no hande ball to play withoute walles, but only greate foote balle
Bandy, ». a game, like that of Golf, in which the ad- verse parties endeavour to beat a ball (generally a knob or gnarl from the trunk of a tree,) opposite ways...the stick with which the game is played is crook'd at the end;. 
By the 19th century, the various forms and divisions of historic games began to differentiate and coalesce into the individual sports defined today. Organizations dedicated to the codification of rules and regulations began to form, and national and international bodies sprang up to manage domestic and international competition.
Main article: Bandy
Bandy is played with a ball on a football pitch-sized ice arena (bandy rink), typically outdoors, and with many rules similar to association football. It is played professionally in Russia and Sweden. The sport is recognized by the IOC; its international governing body is the Federation of International Bandy.
Bandy has its roots in England in the 19th century, was originally called "hockey on the ice", and spread from England to other European countries around 1900; a similar Russian sport can also be seen as a predecessor and in Russia, bandy is sometimes called "Russian hockey". Bandy World Championships have been played since 1957 and Women's Bandy World Championships since 2004. There are national club championships in many countries and the top clubs in the world play in the Bandy World Cup every year.
Main article: Field hockey
Field hockey is played on gravel, natural grass, or sand-based or water-based artificial turf, with a small, hard ball approximately 73 mm (2.9 in) in diameter. The game is popular among both men and women in many parts of the world, particularly in Europe, Asia, Australia, New Zealand, South Africa, and Argentina. In most countries, the game is played between single-sex sides, although they can be mixed-sex.
The governing body is the 126-member International Hockey Federation (FIH). Men's field hockey has been played at each Summer Olympic Games since 1908 except for 1912 and 1924, while women's field hockey has been played at the Summer Olympic Games since 1980.
Modern field hockey sticks are constructed of a composite of wood, glass fibre or carbon fibre (sometimes both) and are J-shaped, with a curved hook at the playing end, a flat surface on the playing side and a curved surface on the rear side. All sticks are right-handed – left-handed sticks are not permitted.
While field hockey in its current form appeared in mid-18th century England, primarily in schools, it was not until the first half of the 19th century that it became firmly established. The first club was created in 1849 at Blackheath in south-east London. Field hockey is the national sport of Pakistan. It was the national sport of India until the Ministry of Youth Affairs and Sports declared in August 2012 that India has no national sport.
Main article: Ice hockey
Ice hockey is played between two teams of skaters on a large flat area of ice, using a three-inch-diameter (76.2 mm) vulcanized rubber disc called a puck. This puck is often frozen before high-level games to decrease the amount of bouncing and friction on the ice. The game is played all over North America, Europe and to varying extents in many other countries around the world. It is the most popular sport in Canada, Finland, Latvia, the Czech Republic, and Slovakia. Ice hockey is the national sport of Latvia and the national winter sport of Canada. Ice hockey is played at a number of levels, by all ages.
The governing body of international play is the 77-member International Ice Hockey Federation (IIHF). Men's ice hockey has been played at the Winter Olympics since 1924, and was in the 1920 Summer Olympics. Women's ice hockey was added to the Winter Olympics in 1998. North America's National Hockey League (NHL) is the strongest professional ice hockey league, drawing top ice hockey players from around the globe. The NHL rules are slightly different from those used in Olympic ice hockey over many categories. International ice hockey rules were adopted from Canadian rules in the early 1900s.
The contemporary sport developed in Canada from European and native influences. These included various stick and ball games similar to field hockey, bandy and other games where two teams push a ball or object back and forth with sticks. These were played outdoors on ice under the name "hockey" in England throughout the 19th century, and even earlier under various other names. In Canada, there are 24 reports of hockey-like games in the 19th century before 1875 (five of them using the name "hockey"). The first organized and recorded game of ice hockey was played indoors in Montreal, Quebec, Canada, on March 3, 1875, and featured several McGill University students.
Ice hockey sticks are long L-shaped sticks made of wood, graphite, or composites with a blade at the bottom that can lie flat on the playing surface when the stick is held upright and can legally curve either way, for left- or right-handed players.
Main article: Sledge hockey
Ice sledge hockey, or "para ice hockey", is a form of ice hockey designed for players with physical disabilities affecting their lower bodies. Players sit on double-bladed sledges and use two sticks; each stick has a blade at one end and small picks at the other. Players use the sticks to pass, stickhandle and shoot the puck, and to propel their sledges. The rules are very similar to IIHF ice hockey rules.
Canada is a recognized international leader in the development of sledge hockey, and much of the equipment for the sport was first developed there, such as sledge hockey sticks laminated with fiberglass, as well as aluminum shafts with hand-carved insert blades and special aluminum sledges with regulation skate blades.
Based on ice sledge hockey, inline sledge hockey is played to the same rules as inline puck hockey (essentially ice hockey played off-ice using inline skates). There is no classification point system dictating who can play inline sledge hockey, unlike the situation with other team sports such as wheelchair basketball and wheelchair rugby. Inline sledge hockey is being developed to allow everyone, regardless of whether they have a disability or not, to complete up to world championship level based solely on talent and ability.
The first game of organized inline sledge hockey was played at Bisley, Surrey, England, on December 19, 2009, between the Hull Stingrays and the Grimsby Redwings. Matt Lloyd is credited with inventing inline sledge hockey, and Great Britain is seen as the international leader in the game's development.
Main article: Roller in-line hockey
Though inline hockey is considered a variant of roller hockey a.k.a. "rink hockey", it was derived from ice hockey instead and uses a type of hockey puck or a ball. Both roller games use a type of wheeled skate but inline hockey uses inline skates rather than roller skates or "quads".
The puck-based inline variant is more commonly played in North America than Europe while the ball-based variant is more popular in Europe.
Inline hockey puck variant is played by two teams, consisting of four skaters and one goalie, on a dry rink divided into two halves by a center line, with one net at each end of the rink. The game is played in three 15-minute periods with a variation of the ice hockey off-side rule. Icings are also called, but are usually referred to as illegal clearing. The governing body is the International Ice Hockey Federation (IIHF), just as it is for ice hockey, but some leagues and competitions do not follow the IIHF regulations, in particular USA Inline and Canada Inline.
Main article: Roller hockey (quad)
Roller hockey, also known as "quad hockey", "international-style ball hockey", "rink hockey" and "Hoquei em Patins", is an overarching name for a roller sport that uses quad skates. It has existed long before the invention of inline skates. The sport is played in over sixty countries and has a worldwide following. Roller hockey was a demonstration sport at the 1992 Barcelona Summer Olympics.
Main article: Street hockey
Also known as road hockey, this is a dry-land variant of ice and roller hockey played year-round on a hard surface (usually asphalt). A ball is usually used instead of a puck, and protective equipment is not usually worn.
Other games derived from hockey or its predecessors include the following:
