Serie A, as it is structured today, began in 1929. From 1898 to 1922 the competition was organised into regional groups. Because of ever growing teams attending regional championships, FIGC split the CCI (Italian Football Confederation) in 1921. When CCI teams rejoined the FIGC created two interregional divisions renaming Categories into Divisions and splitting FIGC sections into two North-South leagues. In 1926 due to internal crises FIGC changed internal settings adding southern teams to the national divisions which lead to 1929-30 final settlement. No title was awarded in 1927 after Torino were stripped of the championship by the Italian Football Federation (FIGC). Torino were declared champions in the 1948-49 season following a plane crash near the end of the season in which the entire team was killed.

The Serie A Championship title is often referred to as the scudetto (small shield) because since the 1924-25 season the winning team will bear a small coat of arms with the Italian tricolour on their strip in the following season. The most successful club is Juventus F.C. with 27 championships, followed by A.C. Milan (17), Internazionale Milano (16) and Genoa C&FC (9). From 2004-05 onwards an actual trophy was awarded to club on the field after the last turn of the championship. The trophy, called Coppa Campioni d’Italia, is official since the 1960-61 season, but between 1961 and 2004 it was consigned to the winning clubs at the offices of Lega calcio in Milan.
