Rugby Football

Rugby football generally refers to either rugby league or rugby union, they are both team sports, rugby union originating at Rugby School in Rugby, Warwickshire, and rugby league originating in Huddersfield, West Yorkshire after splitting and forming the Northern Union in 1895 (what is now known as rugby league). Rugby football (both league and union) is one of many versions of football played at English public schools in the 19th century. Although rugby league initially used rugby union rules, they are now wholly separate sports. In addition to the two existing codes, both codes of Gridiron football (American football and Canadian football) have evolved from rugby football, but themselves also completely different sports altogether. Following the 1895 split in rugby football, the two forms rugby league and rugby union differed in administration only. Soon the rules of rugby league were modified, resulting in two distinctly different forms of rugby. After 100 years, in 1995 rugby union joined rugby league and most other forms of football as an openly professional sport.

The Greeks and Romans are known to have played many ball games, some of which involved the use of the feet. The Roman game harpist is believed to have been adapted from a Greek team game known as "ἐπίσκυρος" (Episkyros) or "φαινίνδα" (phaininda), which is mentioned by a Greek playwright, Antiphanes (388–311 BC) and later referred to by the Christian theologian Clement of Alexandria (c.150-c.215 AD). These games appear to have resembled rugby football. The Roman politician Cicero (106–42 BC) describes the case of a man who was killed whilst having a shave when a ball was kicked into a barber's shop. Roman ball games already knew the air-filled ball, the follies. Episkyros is recognized as an early form of football by FIFA. n 1871, English clubs met to form the Rugby Football Union (RFU). In 1892, after charges of professionalism (compensation of team members) were made against some clubs for paying players for missing work, the Northern Rugby Football Union, usually called the Northern Union (NU), was formed. The existing rugby union authorities responded by issuing sanctions against the clubs, players, and officials involved in the new organization. After the schism, the separate clubs were named "rugby league" and "rugby union".

Rugby union is both a professional and amateur game, and is dominated by the first tier unions: Argentina, Australia, England, France, Ireland, Italy, New Zealand, Scotland, South Africa and Wales. Second and third tier unions include Belgium, Brazil, Canada, Chile, Fiji, Georgia, Germany, Hong Kong, Japan, Kenya, Namibia, the Netherlands, Portugal, Romania, Russia, Samoa, Spain, Tonga, the United States and Uruguay. Rugby Union is administered by World Rugby (WR), whose headquarters are located in Dublin, Ireland. It is the national sport in New Zealand, Wales, Fiji, Samoa, Tonga, Georgia and Madagascar, and is the most popular form of rugby globally. The Olympic Games have admitted the seven-a-side version of the game, known as Rugby sevens, into the programmer from Rio de Janeiro in 2016 inwards. There was a possibility sevens would be a demonstration sport at the 2012 London Olympics but many sports including sevens were dropped. In Canada and the United States, rugby union evolved into gridiron football. During the late 1800s (and even the early 1900s), the two forms of the game were very similar (to the point where the United States was able to win the gold medal for rugby union at the 1924 Summer Olympics), but numerous rule changes have differentiated the gridiron-based game from its rugby counterpart. Among unique features of the North American game are the separation of play into downs instead of releasing the ball immediately upon tackling, the requirement that the team with the ball set into a set formation for at least one second before resuming play after a tackle (and the allowance of up to 40 seconds to do so), the allowance for one forward pass from behind the site of the last tackle on each down, the evolution of hard plastic equipment (particularly the football helmet and shoulder pads), a smaller and pointier ball that is favorable to being passed but makes drop kicks impractical, a generally smaller and narrower field measured in customary units instead of metric (in some variants of the American game a field can be as short as 50 yards between end zones), and a distinctive field (shaped like a gridiron, from which the code's nickname is derived) with lines marked in five-yard intervals. Rugby league is also both a professional and amateur game, administered on a global level by the Rugby League International Federation. In addition to amateur and semi-professional competitions in the United States, Russia, Lebanon, Serbia, Europe and Australasia, there are two major professional competitions—the Australasian National Rugby League and the European Super League. International Rugby League is dominated by Australia, England and New Zealand. In Papua New Guinea it is the national sport. Other nations from the South Pacific and Europe also play in the Pacific Cup and European Cup respectively.

Distinctive features common to both rugby codes include the oval ball and throwing the ball forward is not allowed, so that players can gain ground only by running with the ball or by kicking it. As the sport of rugby league moved further away from its union counterpart, rule changes were implemented with the aim of making a faster-paced and more try-oriented game. The main differences between the two games, besides league having teams of 13 players and union of 15, involve the tackle and its aftermath:
Union players contest possession following the tackle: depending on the situation, either a ruck or a maul can occur. League players may not contest possession after making a tackle: play is continued with a play-the-ball.
In league, if the team in possession fails to score before a set of six tackles, it surrenders possession. Union has no six-tackle rule; a team can keep the ball for an unlimited number of tackles before scoring as long as it maintains possession and does not commit an offense.
Set pieces of the union code include the "scrum", in which packs of opposing players push against each other for possession, and the "line-out", in which parallel lines of players from each team, arranged perpendicular to the touch-line, attempt to catch the ball thrown from touch. A rule has been added to line-outs which allows the jumper to be pulled down once a player's feet are on the ground.

In England, rugby union is widely regarded as an "establishment" sport, played mostly by members of the upper and middle classes. For example, many pupils at public schools and grammar schools play rugby union, although the game (which had a long history of being played at state schools until the 1980s) is becoming increasingly popular in comprehensive schools. Despite this stereotype, the game, particularly in the West Country is popular among all classes. In contrast, rugby league has traditionally been seen as a working class pursuit. Another exception to rugby union's upper class stereotype is in Wales, where it has been traditionally associated with small village teams made up of coal miners and other industrial workers who played on their days off. In Ireland, both rugby union and rugby league are unifying forces across the national and sectarian divide, with the Ireland international teams representing both political entities. In Australia, support for both codes is concentrated in New South Wales, Queensland and the Australian Capital Territory. The same perceived class barrier as exists between the two games in England also occurs in these states, fostered by rugby union's prominence and support at private schools. In France, rugby is widely played and has a strong tradition in the Basque, Occidental and Catalan areas along the border regions between Spain and France. The game is very popular in South Africa, having been introduced by English-speaking settlers in the 19th century. British colonists also brought the game with them to Australia and New Zealand, where the game is widely played. It has spread thence to much of Polynesia, having particularly strong followings in Fiji, Samoa and Tonga. Rugby union continues to grow in the Americas and parts of Asia as well.

A rugby ball, originally called a quango, is a diamond shape ball used for easier passing. Richard Lindon and Bernardo Solano started making balls for Rugby school out of hand stitched, four-panel, leather casings and pigs’ bladders. The rugby ball's distinctive shape is supposedly due to the pig’s bladder, although early balls were more plumb-shape than oval. The balls varied in size in the beginning depending upon how large the pig’s bladder was. In rugby union, World Rugby regulates the size and shape of the ball under Law 2 (also known as Law E.R.B); an official rugby union ball is oval and made of four panels, has a length in-line of 280–300 millimeters, a circumference (end to end) of 740–770 millimeters, and a circumference (in width) of 580–620 millimeters. It is made of leather or suitable synthetic material, and may be treated to make it water resistant and easier to grip. The rugby ball may not weigh more than 460 grams or less than 410 and has an air pressure of 65.71–68.75 kilo pascals, or 0.67–0.70 kilograms per square centimeter, or 9.5–10.0 lbs per square inch. Spare balls are allowed under the condition that players or teams do not seek an advantage by changing the ball. Smaller sized balls may also be used in games between younger players. Much larger versions of traditional balls are also available for purchase, but these are mainly for their novelty attraction. The Rugby World Cup, which was first held in New Zealand and Australia in 1987, occurs every four years. It is an international tournament organized by World Rugby. The event is played in the union format and features the top 20 teams from around the world. The current world champions are New Zealand, who won the 2015 Rugby World Cup, which was played in England.
