Rugby union [SEP] Introduction
World Rugby, previously called the International Rugby Football Board (IRFB) and the International Rugby Board (IRB), has been the governing body for rugby union since 1886, and currently has 101 countries as full members and 18 associate members. In 1845, the first football laws were written by pupils at Rugby School, In Rugby; other significant events in the early development of rugby include the decision by Blackheath F.C. to leave the Football Association in 1863 and, in 1895, the acrimonious split between the then amateur rugby union and the professional rugby league. Historically rugby union was an amateur sport, but in 1995 formal restrictions on payments to players were removed, making the game openly professional at the highest level for the first time.
