was the formation of the Ivy League Rugby Conference in 2010. Following the organization of the Ivy League schools, the members of the Atlantic Coast Conference and the Southeastern Conference followed suit in 2010. Ivy Rugby Conference The Ivy Rugby Conference was formed and had its first full season in 2009. The IRC was formed to foster better competition among rugby teams from the Ivy League schools and to raise the quality of play. The IRC has had consistent success in attracting commercial interests. The IRC formed committees to manage the league, independently of the LAUs and TUs. Prior to formation of the IRC, clubs from the eight Ivy League schools had competed in the Ivy Rugby Championship Tournament since 1969. Southeastern Collegiate Rugby Conference In December 2010, a core group of founding schools formed the Southeastern Collegiate Rugby Conference (SCRC). By April 2010, the SCRC had expanded to 11 schools, comprising the entire membership of the NCAA's Southeastern Conference (SEC) at that time except for Arkansas. Tennessee won the 2010 Southeastern Collegiate Rugby Sevens Championship beating LSU 19–17, and repeated in the 2011 SCRC Olympic Sevens Championship, beating Florida 26–14 in the final. Similar to other conferences, the SCRC has also enjoyed commercial success, announcing in fall 2010 that the SCRC had formed commercial partnership agreements with Adidas and the World Rugby Shop. The Southeastern Collegiate Rugby Conference, formed by the aforementioned 11 SEC schools, was created in late 2010 and began play in the 2011–12 season. Florida won the conference title in the inaugural season, defeating Tennessee in the championship match. Although the SEC has since expanded to 14 schools, the SCRC membership remains at 11. Pacific Athletic Conference Several members of the Pac-12 conference agreed in spring 2012 to form a conference beginning play in the 2012–13 season. Other conferences Nine D1A rugby programs currently compete in the Big Ten Universities conference, which was founded in 2012. The Red River Conference, which replaced the Allied Rugby Conference in 2014–15, is composed mostly of teams from what had been the Big 12 South from 1996 to 2011. The Southwest Conference (SWC) was created in 2011 with charter members from seven Texas schools. University of Texas was immediately added, and Texas won the conference in the inaugural 2011–12 season. Other competitions College rugby includes rivalry trophies such as the World Cup between the University of California, Berkeley and the
