The history of rugby union follows from various football games long before the 19th century, but it was not until the middle of that century that the rules were formulated and codified. The code of football later known as rugby union can be traced to three events: the first set of written rules in 1845, the Blackheath Club's decision to leave the Football Association in 1863 and the formation of the Rugby Football Union in 1871. The code was originally known simply as "rugby football". It was not until a schism in 1895, over the payment of players, which resulted in the formation of the separate code of rugby league, that the name "rugby union" was used to differentiate the original rugby code. For most of its history, rugby was a strictly amateur football code, and the sport's administrators frequently imposed bans and restrictions on players who they viewed as professional. It was not until 1995 that rugby union was declared an "open" game, and thus professionalism was sanctioned by the code's governing body, World Rugby—then known as the International Rugby Football Board (IRFB).

Antecedents of rugby union

Primitive forms of football included harpastum, played by the Roman where two opposing teams competed to throw a large ball into an opposition net, fighting for possession of the ball. Medieval Irishmen played caid, carrying an inflated bladder and using arched trees as goals. The Welsh played an inter-parish game using a wooden ball called cnapan. Frenchmen played soule and Georgians played lelo burti.

Other forms of traditional football similar to rugby have been played throughout Europe and beyond. Many of these involved handling of the ball, and scrummaging formations. For example, New Zealand had Ki-o-rahi, Australia marn grook, Japan kemari, the Scottish Borders Jeddart Ba' and Cornwall Cornish hurling, Central Italy Calcio Fiorentino, East Anglia Campball.

The first detailed description of what was almost certainly football in England was given by William FitzStephen in about 1174–1183. He described the activities of London youths during the annual festival of Shrove Tuesday:

Numerous attempts were made to ban football games, particularly the most rowdy and disruptive forms. This was especially the case in England, and in other parts of Europe, during the Middle Ages and early modern period. Between 1324 and 1667, in England alone, football was banned by more than 30 royal and local laws. The need to repeatedly proclaim such laws demonstrated the difficulty in enforcing bans on popular games. King Edward II was so troubled by the unruliness of football in London that, on 13 April 1314, he issued a proclamation banning it:

In 1531, Sir Thomas Elyot wrote that English "Foote balle is nothinge but beastlie furie and extreme violence".

While many of these statutes were in practice obsolete by the 1700s, they remained technically enforceable in law, until all doubts were removed by the Gaming Act 1845.

Football games that included ball carrying continued to be played over the century, right up to the time of William Webb Ellis's alleged invention. One form, recorded as early as 1440The first ever English-Latin dictionary, Promptorium parvulorum (ca. 1440), offers the following definition of camp-ball: "Campan, or playar at foott balle, pediluson; campyon, or champion" and which persisted until the 19th century, was an East Anglian game called variously Camping, Campan, Camp-ball and Campyon which was explicitly based on carrying the ball and tossing it from player to player in order to continue the advance. According to an observer writing in 1823 (coincidentally the year of rugby's "invention"),

19th century Early history

"Football" as a game was well established by 1803 at Rugby school and by the 1830s, "running in" with the ball in hand was allowed but subject to hacking and "collaring".

Playing football has been a long tradition in England and versions of football had probably been played at Rugby School for 200 years before three boys published the first set of written rules in 1845. The rules had always been determined by the pupils instead of the masters and they were frequently modified with each new intake. Rule changes, such as the legality of carrying or running with the ball, were often agreed shortly before the commencement of a game. There were thus no formal rules for football during the time that William Webb Ellis was at the school (1816–25) and the story of the boy "who with a fine disregard for the rules of football as played in his time, first took the ball in his arms and ran with it" in 1823 is apocryphal. The story first appeared in 1876, some four years after the death of Webb Ellis, and is attributed to a local antiquarian and former Rugbeian Matthew Bloxam. Bloxam was not a contemporary of Webb Ellis and vaguely quoted an unnamed person as informing him of the incident that had supposedly happened 53 years earlier. The story has been dismissed as unlikely since an official investigation by the Old Rugbeian Society in 1895. However, the cup for the Rugby World Cup is named the Webb Ellis trophy in his honour, and a plaque at the school commemorates the "achievement".

Rugby football has strong claims to the world's first and oldest "football club": the Guy's Hospital Football Club, formed in London in 1843, by old boys from Rugby School. Around the English-speaking world, a number of other clubs formed to play games based on the Rugby School rules. One of these, Dublin University Football Club, founded in 1854, has arguably become the world's oldest surviving football club in any code. The Blackheath Football Club, in London, founded in 1858 is the oldest surviving non-university/school rugby club. Cheltenham College 1844, Sherborne School 1846 and Durham School 1850 are the oldest documented school's clubs. Francis Crombie and Alexander Crombie introduced rugby into Scotland via Durham School in 1854.. The first rugby club in Wales was at St David's College, Lampeter, founded in around 1850 by Rowland Williams.

Ball Until the late 1860s, rugby was played with a leather ball with an inner-bladder made of a pig's bladder. The shape of the bladder imparted a vaguely oval shape to the ball, but they were far more spherical in shape than they are today. A quote from Tom Brown's Schooldays, written by Thomas Hughes (who attended Rugby School from 1834 to 1842), shows that the ball was not a complete sphere:

In 1851, a football of the kind used at Rugby School was exhibited at the first World's Fair, the Great Exhibition in London. This ball can still be seen at the Webb Ellis Rugby Football Museum and it has a definite ovoid shape. In 1862, Richard Lindon introduced rubber bladders and, because of the pliability of the rubber, balls could be manufactured with a more pronounced shape. As an oval ball was easier to handle, a gradual flattening of the ball continued over the years as the emphasis of the game moved towards handling and away from dribbling. In 1892, the RFU included compulsory dimensions for the ball for the first time in the Laws of the Game. In the 1980s, leather-encased balls, which were prone to water-logging, were replaced with balls encased in synthetic waterproof materials.

Schism between the Football Association and rugby football The Football Association (FA) was formed at the Freemason's Tavern, Great Queen Street, on Lincoln Inn Fields, London, on 26 October 1863, with the intention of framing a code of laws that would embrace the best and most acceptable points of all the various methods of play under the one heading of football. At the beginning of the fourth meeting, attention was drawn to the fact that a number of newspapers had recently published a new version of the Cambridge rules. The Cambridge rules differed from the draft FA rules in two significant areas, namely "running with the ball" and "hacking" (kicking an opponent in the shins). The two contentious draft rules were as follows:

At the fifth meeting, a motion was proposed that these two rules be expunged from the FA rules. Francis Maule Campbell, a member of the Blackheath Club, argued that hacking is an essential element of "football" and that to eliminate hacking would "do away with all the courage and pluck from the game, and I will be bound over to bring over a lot of Frenchmen who would beat you with a week's practice".Staff.World Rugby Chronology ,World Rugby Museum . Retrieved 2008-11-10. See 1 December 1863 – 5th FA meeting. At the sixth meeting, on 8 December, Campbell withdrew the Blackheath Club, explaining that the rules that the FA intended to adopt would destroy the game and all interest in it. Other rugby clubs followed this lead and did not join the Football Association.

Formation of the first rugby union

On 4 December 1870, Edwin Ash of Richmond and Benjamin Burns of Blackheath published a letter in The Times suggesting that "those who play the rugby-type game should meet to form a code of practice as various clubs play to rules which differ from others, which makes the game difficult to play." On 26 January 1871, a meeting attended by representatives from 21 clubs was held in London at the Pall Mall restaurant.

The 21 clubs and schools (all from London or the Home Counties) attended the meeting: Addison, Belsize Park, Blackheath (represented by Burns and Frederick Stokes the latter becoming the first captain of England), Civil Service, Clapham Rovers, Flamingoes, Gipsies, Guy's Hospital, Harlequins, King's College, Lausanne, The Law Club, Marlborough Nomads, Mohicans, Queen's House, Ravenscourt Park, Richmond, St Paul's, Wellington College, West Kent, and Wimbledon Hornets. The one notable omission was the Wasps who "In true rugby fashion … turned up at the wrong pub, on the wrong day, at the wrong time and so forfeited their right to be called Founder Members".

As a result of this meeting, the Rugby Football Union (RFU) was founded. Algernon Rutter was elected as the first president of the RFU and Edwin Ash was elected as treasurer. Three lawyers, who were Rugby School alumni (Rutter, Holmes and L.J. Maton), drew up the first laws of the game; these were approved in June 1871.

These laws were then taken up as the founding or very early rules of the Scottish FU (1873), Southern RFU (1874) in Australia, the Intercollegiate FA (1876) in America, the Welsh FU (1881), the original Canadian RFU (1882) and the first of the various provincial bodies in New Zealand (including Canterbury RFU) and what became South Africa (Western Province RFU).

First international game

The first international football game resulted from a challenge issued in the sporting weekly Bell's Weekly on 8 December 1870 and signed by the captains of five Scottish clubs, inviting any team "selected from the whole of England" to a 20-a-side game to be played under the Rugby rules. The game was played at Raeburn Place, Edinburgh, the home ground of Edinburgh Academical, on 27 March 1871.

This is not only the first international rugby match, but the first genuine international of any form of football because, despite the fact that three England v Scotland fixtures had already been played according to association football rules at The Oval, London, in 1870 and 1871, these are not considered full internationals by FIFA, as all but one of the players competing in the Scotland team were London-based footballers who claimed a Scottish family connection rather than being truly Scottish.

The English team wore all-white with a red rose on their shirts and the Scots wore brown shirts with a thistle and white cricket flannels. The England team was captained by Frederick Stokes of Blackheath, that representing Scotland was led by Francis Moncrieff; the umpire was Hely Hutchinson Almond, headmaster of Loretto School.
