The Rugby Championship (until 2011: The Tri Nations) is an international rugby union competition contested annually by Australia, New Zealand, South Africa and from 2012, Argentina. The competition is organized by SANZAR, a consortium formed by the governing bodies of the Australian Rugby Union, the New Zealand Rugby Union and the South African Rugby Union.
The former three teams compose the sport's elite, and between them have won six out of the seven Rugby World Cups, in addition to maintaining positive win records against all competitors of the Six Nations Championship. The high degree of competitive success and dominance in the rankings of these participating countries leads many to consider the Rugby Championship the toughest annual rugby union competition in the world.
While historically weaker, Argentina's level of play has equaled the stronger half of the Six Nations since the 2000s, and proved their worth in the Rugby Championship with a 16-16 draw to the Springboks in only their second test.
