Medveščak Zagreb II played in the 2003–04 Panonian League. At the end of the regular season they finished sixth out six teams and they failed to qualify for the play-offs. They made their debut in the Croatian Ice Hockey League in 2004–05, helping to make up the numbers in a depleted four team league. During the 2009-10 season they played in both the Slohokej Liga and the CIHL, winning the latter title. When the senior Medveščak team left the Croatian Ice Hockey League permanently to play initially in the Austrian Hockey League and later the KHL, their place in the CIHL was effectively filled by Medveščak II. The farm team has since won a further two national league titles. They won the 2013–14 title with the help of reinforcements from their senior team after they had been eliminated earl
