Founded 15 February 1915 as US Livorno, the club ended the Italian Football Championship 1919–20 in second place, losing the final to Internazionale. One year later, they were defeated in the semi-final by arch-rivals Pisa. In 1933, the club moved to the current stadium, originally named after Edda Ciano Mussolini, daughter of fascist dictator Benito Mussolini. Livorno was one of the original Serie A teams. They played in top level during periods of 1929–31, 1933–35 and 1937–39. Successively, Livorno ended as Serie A runners-up in the 1942–43 season. Livorno left Serie A in 1949 after seven consecutive seasons. They were relegated to Serie C soon after (1951–52 season), making a return to Serie B in 1955 for a single season and again from 1964 to 1972. They relegated to Serie C2 in 1982–83 and played again in third level between 1984 and 1989. The club was then cancelled in 1991, being forced to start from Eccellenza; two consecutive promotions led the team back to Serie C2. The club was promoted to Serie C1 in 1997 and was acquired by Aldo Spinelli two years later. Under the new property, Livorno returned to Serie B in 2001.
