The United Rugby Championship (URC) is an annual rugby union competition involving professional teams from Ireland, Italy, Scotland, South Africa, and Wales. The current name was adopted in 2021 when the league expanded to include four South African teams previously from the SANZAR Super Rugby competition. The league is one of the three major professional leagues in Europe (along with the English Premiership and the French Top 14), the most successful teams from which go forward to compete in the European Rugby Champions Cup. Since 2022–23, despite the name, South African teams have been eligible to qualify for European competition, and one South African place is guaranteed. Beginning with the creation of the Welsh–Scottish League in 1999, the league became known as the Celtic League when it grew to include teams from Ireland, Scotland and Wales. The league was sponsored by Irish cider makers Magners from the 2006–07 season until 2010–11. At the start of the 2010–11 season, the league expanded from 10 to 12 teams, adding two Italian teams. Following the end of Magners' sponsorship, the league was sponsored by RaboDirect from 2011–12 through to 2013–14. The Pro12 name was adopted in 2011 to reflect that the league now included teams from outside the Celtic nations. A further expansion to 14 teams (and the subsequent renaming to Pro14) took place from the 2017–18 season, with two South African teams joining the Championship until the 2019–20 season. The recent sponsorship deal with Guinness began at the beginning of the 2014–15 season, and concluded after the Pro14 Rainbow Cup in July 2021. Following the rebranding to the United Rugby Championship or the URC for short, the league formed a new partnership with Roc Nation. Tournament format Current format The championship season as of 2021–22 takes place between September and May, with teams split into four regional pools: The Irish Shield pool, the Welsh Shield pool, the South African Shield pool and the Scottish and Italian Shield pool. Teams will also be sorted into a single league table. Teams will play each of the other teams in their pool twice (home and away) and each team from the other pools once (either home or away). This ensures that Irish, South African and Welsh teams each play six derby matches. For Italy and Scotland, their respective clubs will play their own nations' sides only twice. This creates an 18-match regular season before the
