The European Rugby Champions Cup is a major European rugby competition involving the leading clubs from England, Scotland, Ireland, Wales, France and Italy. It began in the 1995–96 season as the Heineken Cup, with sponsorship from major brewery Heineken, and kept that name through the 2013–14 season. Disagreements between the leagues that sent teams to the competition led to the end of the Heineken Cup, with the Champions Cup taking its place starting in 2014–15.
