Slovenian First League in 1997, when it also took the name of its sponsor,
Krka. A fourth-place finish in the national league allowed the club to qualify for the
Korać Cup for the 1998–99 season. The big breakthrough came a year later, however, as Krka defeated historical rival
Olimpija in the Slovenian championship finals to win the national title. That year, the team also played in the
