 The longest run of Old Firm wins is 11 between 1971 and 1981, while the longest run of other winners since Celtic's formation is 5 between 1955 and 1959.Rangers' sudden if temporary removal from the upper echelons of the Scottish game in 2012 led to a more diverse list of finalists in both cups; the expected Celtic monopoly of all competitions did not occur in the knockout formats and there were several maiden trophy wins for clubs such as St Johnstone, Inverness CT and Ross County.On six occasions (Hibernian in 1901–02, St Mirren in 1925–26, Kilmarnock in 1928–29, Hearts in 1955–56, Aberdeen in 1982–83 and again in 1983–84) the winners of the Scottish Cup defeated both Rangers and Celtic en route to lifting the trophy.
