The Rugby Championship is an annual international rugby union competition featuring four teams: New Zealand, Australia, South Africa, and Argentina. It was established in 2012, replacing the Tri Nations tournament, and is held in the Southern Hemisphere. Each team plays the others twice, once at home and once away, accumulating points to determine the champion. The tournament typically takes place from August to October, with matches played in various stadiums across the participating countries. The team with the most points at the end of the competition is crowned the champion, while individual matches contribute to the overall standings and rivalries among the teams.
