AS Roma was founded in the spring of 1927 when Italo Foschi initiated the merger of three older Italian Football Championship clubs from the city of Rome: Roman FC, SS Alba-Audace and Fortitudo-Pro Roma SGS
Their first honour outside of Italy was recorded in 1960-61 when Roma won the Inter-Cities Fairs Cup by defeating Birmingham City 4-2 in the finals. A few years later, Roma won their first Coppa Italia trophy in 1963-64, after defeating Torino 1-0.
The dawning of a newly successful era in Roma's footballing history was brought in with another Coppa Italia victory; they defeated Torino on penalties to win the 1979-80 edition. Roma would reach heights in the league which they had not touched since the 1940s by narrowly and controversially finishing as runners-up to Juventus in 1980-81. Former Milan player Nils Liedholm was the manager at the time, with players such as Bruno Conti, Agostino Di Bartolomei, Roberto Pruzzo and Falcao.
Roma won their third Serie A title in 2000-01. The Scudetto was won on the last day of the season after defeating Parma 3-1, edging Juventus by two points. The club's captain, Francesco Totti, was a large reason for the title victory and he would become one of the main heroes in the club's history, going on to break several club records. Other important players during this period included: Aldair, Cafu, Gabriel Batistuta and Vincenzo Montella.
In December 2019, AS Roma SPV LLC was in final negotiations to sell the team for $872 million, to American businessman Dan Friedkin, however negotiations stalled during the COVID-19 pandemic. On 6 August 2020, Friedkin signed the preliminary contract to agree to pay $591 million to Pallotta, the main shareholder of Roma. Paulo Fonseca, who was hired as manager in 2019, left two years later and was replaced by fellow Portuguese Jose Mourinho. On 25 May 2022, he led Roma to win the inaugural edition of UEFA Europa Conference League, defeating Feyenoord in the final.
