The Nations Championship is the new biennial international rugby tournament created by Six Nations Rugby and SANZAAR and featuring all 10 of the associated unions and federations, plus two invitational teams. The tournament will take place every two years, outside of Rugby World Cup and British & Irish Lions Tour year's, enhancing the existing July and November international windows within the rugby calendar.
By enhancing these windows, Six Nations Rugby and SANZAAR are creating a tournament format that carries competitive jeopardy, with points, rankings and silverware on offer. The tournament signals the first time in the sport's history that the biggest nations in rugby have come together to create a cohesive and competitive tournament format and will stand as the biggest evolution in the game, since it turned professional in 1995.
