 Although the rivalry between Serbian and Croatian clubs was kept, and will be particularly intense during the last years before the break-up of the country when the ethnic tensions were high, the number of championships won by Belgrade clubs was much higher and proportionally increased in comparison with the pre-1945 period when the relation was balanced.In total, in this period, Red Star won most of the championships, 19, with Partizan being in second place with 11, Hajduk Split won 7 and Dinamo Zagreb, the successor of pre-1945 Građanski, 4.Another Serbian club, FK Vojvodina won 2 titles, and this period was also characterised by the appearance of clubs from Bosnia and Herzegovina as championship winning teams, with FK Sarajevo winning 2, and FK Željezničar, also from Sarajevo, winning one.
