In 1994-95 and 1995-96, the Alpenliga was part of a larger competition called the Six Nations Tournament (sometimes called Europäischer Ligacup or Coupe des Ligues Européennes), which pitted its top teams against members of the Atlantic League, another crossborder loop composed of French, Dutch and Danish clubs.
After 1999, the Alpenliga was replaced with the International Ice Hockey League (often shortened to Interliga), first contested 1999-2000. Eight clubs from Austria, Hungary and Slovenia including, HC Alba Volan, HK Acroni Jesenice, Dunaferr SE, Erste VEU Feldkirch, EC Klagenfurter, HK Olimpija, VSV Villach and WEV Wiener played the first season. The league winners were Villacher SV, and playoff champions were Klagenfurter EC.
After just one season, Austrian teams quit the International Ice Hockey League, and were replaced with Croatian clubs. Yugoslavian, Slovak and Polish organizations also made appearances over the years. The Interliga ceased operations following the 2006-07 season.

|1991-92 HC Devils Milano|
