Rugby union and apartheid had a complex relationship. From 1948 to 1994, international rugby relations with the country, and also the non-integrated nature of rugby within South Africa drew frequent controversy. South Africa remained a member of the International Rugby Board (IRB) throughout the apartheid era.
Halt All Racist Tours was established in New Zealand in 1969 to oppose continued tours to and from South Africa. Though contacts were restricted after the Gleneagles Agreement in 1977, there were controversial tours in 1980 by the British Lions and by France, in 1981 by Ireland, and in 1984 by England. South Africa toured New Zealand in 1981. South Africa were excluded from the first two Rugby World Cups, in 1987 and 1991. Racially selected New Zealand sports teams toured South Africa until the 1970 All Blacks rugby tour allowed Māori to go under the status of 'honorary whites'.
No other issue, political or otherwise has divided the rugby community so much, at least not since the great schism with rugby league over professionalism. While many rugby fans and commentators would try and body swerve politics, at least politics of a certain kind, the apartheid issue brought it right into the heart of the game, in a very direct, and often physical way. The issue particularly came to the fore in the seventies and eighties. Unlike the split in the rugby world though, the apartheid issue attracted considerable interest from outside the sporting world.
