The league was founded in 2008, taking over previous league's significance (National Football League Italy). The league was born as a result of the escape of several of the best clubs of the old championship organized by the Italian federation, such as Milano Rhinos, Parma Panthers, Bologna Doves and Bolzano Giants. However some of the historic Italian clubs have not joined the new league and continue to participate in different tournaments organized by other federations. This is the case of Legnano Frogs, Torino Giaguari, etc. In the following years a lot of teams moved to the FIDAF (the federation where the IFL belongs to) and most of the biggest teams are now part of the IFL that is the First Division or in the other 2 divisions.
♦ due to league expansion the Napoli team can play the 2015 IFL season and is not relegated to the second division
‡ Roma Grizzlies won the second division championship and earned the right to play the 2015 IFL season
