Which rugby union tournament was first called the Heineken Cup?

The tournament first called the Heineken Cup is now the European Rugby Champions Cup.

The competition began in 1995–96 as the Heineken Cup, bringing leading professional clubs from Europe’s domestic leagues into a cross-border championship. Sponsorship and organisational changes later affected its name and structure.

From the 2014–15 season, the principal tournament became the European Rugby Champions Cup, while the second-tier competition became the European Rugby Challenge Cup. The Champions Cup is organised by European Professional Club Rugby, commonly abbreviated EPCR.

The competition is distinct from the Rugby World Cup, which is contested by national teams. It is also separate from domestic league championships, although qualification for the Champions Cup is generally linked to performance in those leagues.
