Italie - Série A2

The league was created in May 1974, by the Lega Basket, the organisation in charge of running the LBA (to this day), that decided to create a new second division with 10 clubs. The two that were relegated during that season, and 8 from the now-former second tier Serie B, chosen with an on and off the court criteria.

The 1975–76 season saw 12 clubs take part, after a complicated system had seen a transfer of clubs from the Serie A1 to the A2.

In June 2001, the LegaDue was created to replace the Serie A2. Lega Basket now took part in running the league, though a system of promotion and relegation between the leagues remained.

During the 2013 summer, another revamp was decided. The LegaDue was amalgamated with the third division DNA, to form a two-tiered league, the DNA (Divisione Nazionale A) Gold and DNA Silver. The two DNA's had separate season's, but the first ranked team in DNA Silver joined the seven best Gold teams to compete for the single promotion spot in the Serie A. The next best eight Silver squads fought for one spot in the next Gold season, whilst the three worst teams were relegated.

The next season saw the league retake its Serie A2 moniker, keeping a similar but tweaked hybrid model, with the eight best Gold and the four best Silver teams taking part in the promotion playoffs (still for the one spot), whilst the last two Gold and the penultimate and ante-penultimate Silver squads play a relegation play out (the last ranked Silver team was relegated outright).
