Unione Sportiva Livorno 1915 (formerly A.S. Livorno Calcio, commonly known as Livorno), is a semi-professional Italian football club based in Livorno, Tuscany. They compete in Serie D, the top tier of semi-professional Italian football after their promotion from the regional Eccellenza Tuscany league. The team's colours are dark red ( in Italian, from which the team nickname derives). Livorno were one of the original sides of Serie A, but since the 1950s have been mostly outside of the top flight due to two club refoundings in 1991 and 2021, which necessitated a start from the Eccellenza. Their best placement in Italian Serie A was second place in 1942–43 season, during which the gave life to a head-to-head competition with Torino. US Livorno play their home matches at the Stadio Armando Picchi. History Founded 15 February 1915 as A.S. Livorno Calcio, 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. Livorno were promoted to Serie A after finishing third in the Serie B 2003–04, one of six clubs to be promoted that season. It had been 55 years since Livorno's last season in the top flight, and as a result of this, most were predicting an instant return to Serie B for the club. The first match in the major league was attended by Italian President Carlo Azeglio Ciampi, a Livorno's citizen
