Rugby is a type of football developed at Rugby School in Rugby, Warwickshire, one of many versions of football played at English public schools in the 19th century. The two main types of rugby are rugby league and rugby union. Although rugby league initially used rugby union rules, they are now wholly separate sports.
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 harpastum 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 follis.Episkyros is recognised as an early form of football by FIFA.
In 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".
