'''Harpastum Rugbeiense''' ([[Anglice]] ''Rugby football'') est uterque ex duobus ludis similaribus, in quibus duo manipuli pilam ovalem portant, inter se iaciunt, ac calce petunt. Primus ludus, [[Harpastum XV|harpastum Rugbeiensis unionis]] (quindecim lusoribus), in [[schola Rugbeiensis|schola Rugbeiensi]] [[Rugbeia]]e in Anglia ortus est. Ex quo post conscissionem anni [[1895]] factus est secundus ludus, [[harpastum Rugbeiensis ligae]], tredecim lusoribus lusum. Harpastum Rugbeiense aliquantum similis est [[harpastum Americanum|harpasto Americano]] et [[harpastum Canadensis|harpastum Canadensi]].
'''Rugby football''' refers to the team sports rugby league and [[Harpastum XV|rugby union]]. Rugby union originated at Rugby School in Rugby, Warwickshire and rugby league originated in Huddersfield, [[Isuria Occidentalis|West Yorkshire]] after splitting to form the Northern Rugby Football Union in 1895, today called the Rugby Football League. Rugby football (both league and union) is one of many versions of football played at English public schools in the 19th century.<ref>[http://www.rugbyfootballhistory.com/originsofrugby.htm Rugby Football History]</ref> 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 each has key differences.

Following the 1895 split in rugby football, the two forms rugby league and [[Harpastum XV|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.<ref>{{cite news|last=Gilbert|first=Ian|title=The bluffer's guide|url=http://w[[The Age]]|date=10 October 2003|deadurl=yes|archiveurl=https://web.archive.org/web/20130715160210/http://w/|archivedate=15 July 2013|df=dmy-all}}</ref>
