The club was founded as FC Varaždin Football School (Croatian: NK Varaždin Škola nogometa, Varaždin ŠN) as a phoenix club of NK Varaždin (1931–2015) in 2012 after the latter's suspension;[1] the club was dissolved during the second part of the 2011–12 season due to high financial debt. Legally, the two clubs' track records and honours are kept separate by the Croatian Football Federation, but the 2012 club is a continuation of the older club, which did return to competition in 2013, overlapping with the life of Varaždin ŠN. However, the older club finally declared bankruptcy and dissolved in 2015, leaving the name NK Varaždin available once again.[2]
