The Lega Italiana Calcio Professionistico, commonly known as Lega Pro (Pro League), is the governing body that runs the eponymous third highest football division in Italy.
In the last edition (2013–14), Prima Divisione consisted of two groups: Girone A and Girone B, respectively of 17 and 16 teams. At the end of the season, four teams (two from each group) go up to Serie B and six teams (three from each group) go down to Lega Pro Seconda Divisione.
Also Seconda Divisione consisted of two groups: Girone A and Girone B, but both of 18 teams. At the end of the season, six teams (three from each group) go up to Lega Pro Prima Divisione and nine teams (four from each group plus the loser play-out from each division) go down to Serie D. In both the Seconda Divisione, teams are split by geographical criteria, with the exception of the Sicilian team Milazzo that plays in group A.
The Seconda Divisione, until the summer 2010 consisted of 54 teams, but in the season 2010–11 the teams were only 49 divided geographically into three divisions of 17, 16 and 16 teams each. At the end of the season, six teams (two from each group) went up to the Prima Divisione and four: two for the group A and one for each of the other two groups, went down to Serie D.
On 21 November 2012, it was announced that the two levels would be merged into a unique league composed by three groups of 20 teams each starting from the 2014–15 season. The merge became effective with the 2014–15 Lega Pro season.
The 2014–15 Lega Pro Divisione Unica is the first season of the unified Lega Pro division in place of the old Prima Divisione and Seconda Divisione. The league is composed of 60 teams divided into three different groups of 20 each
