In August 1920, Foot Ball Club Empoli and the football section Unione Sportiva Empoli were born. After the participation of a tournament in San Miniato, the two merged into a single local football club. The next season, the new club, after having obtained in September affiliation in the Italian Football Federation (FIGC) ratified by the Tuscan Regional Committee, was included in Group A of the Tuscan Promozione 1921–22, but did take part due to economic problems, choosing instead to join the league of Terza Categoria, where the team achieved second place in the group A.

In the 1922–23 season, Empoli finished in second place in Group A of the Terza Categoria, gaining admission to the final round after winning the play-off in Florence, held on 15 April 1923 against Pontedera, 1–0. The season concluded with a third place in the group final.
